SIP Over TCP
To guarantee state-oriented communications, Linksys voice devices introduce the option of choosing
TCP as the transport protocol for SIP with Release 5. This protocol is “guaranteed delivery”, which
assures that lost packets are retransmitted. TCP also guarantees that the SIP packages are received in the
same order that they were sent. As a result, TCP overcomes the main disadvantages of UDP. In addition,
for security reasons, most corporate firewalls block UDP ports. With TCP, new ports do not need to be
opened or packets dropped, because TCP is already in use for basic activities such as Internet browsing
or e-commerce.
Because these advantages may require more processing power, SIP over TCP has been developed in the
most robust Linksys platforms.
SIP Over TLS
SIP Over TLS eliminates the possibility of malicious activity by encrypting the SIP messages by the SIP
proxy of the service provider and the end user. SIP Over TLS relies on the widely-deployed and
standardized Transport Layer Security (TLS) protocol. Note that SIP Over TLS encrypts only the
signaling messages and not the media. A separate secure protocol such as Secure Real-Time Transport
Protocol (SRTP) can be used to encrypt voice packets.
Media Loopback
Service providers can use media loopback to quantitatively and qualitatively measure the voice quality
experienced by the end user. One device acts as the audio transmitter and receiver while the other device
acts as the audio mirror. The audio mirror transmits the audio packets that it receives back to the
transmitter/receiver instead of transmitting the data sampled on its local microphone (IP phone) or
attached analog telephone (ATA-type device).
Release Notes for Linksys SPA Firmware Release 5.x

Document Version 3.1
New Features in Firmware Version 5.x
Register Retry Enhancements
The Register Retry Enhancements feature adds additional flexibility to the delay timers that are activated
when the SIP REGISTER of a device fails. The timers are selected based on the failure response code
sent by the SIP proxy. Depending on the type of registration failure, either a short timer or a long timer
is activated. The new available parameters are as follows:
•
Reg_Retry_RSC—List of response codes to use the short timer
•
Reg_Retry_Random_Delay—Minimum and maximum random delay to be added to the short timer
•
Reg_Retry_Long_Random_Delay—Minimum and maximum random delay to be added to the long
timer
•
Reg_Retry_Intvl_Cap—Maximum value of the exponential delay
DHCP Renewal on Timeout
Linksys voice devices typically operate in a network where a DHCP server assigns the device its IP
address. Because IP addresses are a limited resource, the DHCP server periodically renews the device
lease on the IP address. Therefore, if a device loses its IP address for any reason, or if some other device
on the network is assigned its IP address, the communication between the SIP proxy and the device is
either severed or degraded.
Whenever an expected SIP response is not received within a programmable amount of time after the
corresponding SIP command is sent, the DHCP Timeout on Renewal feature causes the device to request
a renewal of its IP address. If the DHCP server returns the IP address that it originally assigned to the
device, the DHCP assignment is presumed to be operating correctly. Otherwise, the device resets to try
to fix the issue.
GUI Localization
The GUI Localization feature for the SPA900 series telephones enables the Linksys IP phone menu to
be displayed in languages other than English. This feature applies to all the SPA900 Series phones that
have a display.
Downloadable Auto-Attendant Prompts
In Release 5, an option is added to download a pre-recorded sound clip into any of the ten auto-attendant
messages through the SPA9000 Ethernet network interface.
API for Computer-Telephony Interface
The Computer-Telephony Interface (CTI) API for the SPA9000 was designed and implemented to
enable adjunct applications and services to have configurable control over SPA9000 endpoints as well
as to provide the potential for tight integration with third-party applications residing on the PC of the
SPA900 Series IP phone user.

New Features in Firmware Version 5.x
Initial INVITE and MWI Challenge
Starting with Release 5, the SIP INVITE (initial) and MWI message in a session can be challenged by
the endpoint. The purpose of this challenge is to restrict the SIP servers that are permitted to interact
with the devices on the service provider network, which significantly increases the security of the VoIP
network by preventing malicious attacks against the device.

Firmware Version 5.1.8
•
When swapping calls in a call-waiting or similar situation, the SPA will order the operations to make
sure that call hold is invoked before call resume.
•
Use the value from the Retry-After header in a 5xx response to Register request to schedule the next
Register retry, if the header is present. If this Retry-After is present, all the statically configured
retry timer values are ignored.
•
Do not accept Media Loop Back calls (reply Busy) if the phone is already off-hook. If the user takes
the phone off-hook while a media loopback call is in session, the unit will end the media loopback
call immediately.
Resolved Caveats (SPA9000)
Fixed this problem: Shared line fails to work as expected on some phones after a while.
Removed Yahoo! from Info web page
Fixed this problem: When ITSP reply 100 to outbound INVITE with a TO-Tag, followed by a 407 to
challenge the INVITE, the 9000 will terminate the call as if the call has failed.
Fixed this problem: Unit stops playing incoming RTP audio once it receives a 180/183 w/o SDP;
regardless setting of <Sticky 183> parameter
9000 might reboot randomly when STUN is enabled.
In the error case when the external ITSP fails to send an ACK to the 9000 after it sends 200 to the
INVITE, the 9000 might reboot if the call was answered by the AA and transferred to a hunt group
9000 should not include the additional margin in the expires parameter of the Contact header in response
to station REGISTER requests

is now configurable with SCA Barge In Enable parameter.
Resolved Caveats (SPA962)
The following issues, which were resolved in Firmware Version 5.1.7, apply to SPA962:
•
Phone does not play network ringback even if early media is negotiated to G711.
•
Phone does not use the same Authorization header fields in the ACK as in the corrsponding INVITE,
per RFC 3261.
•
Entering '#' terminates dialing.
•
Sending keep-alive message to $PROXY does not work when SIP transport is TCP/TLS
•
200 response to reINVITE does not contact transport parameter in the Contact header (which is
necessary when transport is TCP/TLS).
•
When using the dictionary, the web server enable option turns off by itself when any network
configuration is changed using GUI. This was caused by a comparision of "yes" to the translated
version of "yes".

Release Notes for Linksys SPA Firmware Release 5.x
Document Version 3.1

Firmware Version 5.1.7
"strict" dtmf tx mode works for AVT. Before it only works for SIP info.
Accept %xx escape syntax in <NAT Keep Alive Msg> paramter. For example %0d%0a will be
unescaped into \r\n (CRLF).
Added QoS policy feature to allow user to activate Qos only when phone is in use. New parameter "QoS
Policy" is added with two options: "Always On" and "On When Phone In Use."
If REGISTER results in a 301 response with a Contact header that has a maddr URI parameter, and if
the <Outbound Proxy> is an IP address, the SPA will change the outproxy proxy address to the value
of the maddr address. This value will remain valid until the next 301 response, if any, or will restore to
the originally configured value upon reboot.
Resolved Caveats (SPA9000)
•
Fixed this problem: Unit does not use the same Authorization header fields in the ACK as in the
corresponding INVITE, per RFC 3261.
•
Fixed this problem: If <SIP Transport> is set to TCP or TLS, unit might not send keep alive
messages properly when destination is $PROXY.
•
Fixed this problem: When <SIP Transport> is TCP/TLS, unit does not include transport=tcp or
transport=tls, respectively in the Contact header's URI in the 200 OK response to an re-INVITE
request.
•
Fixed this problem: Added the missing character u and l for IVR
•
SDP in INVITE response, includes annexb=yes/no if present in INVITE message.
•
Fixed this problem: 9000 includes extra CR/LF at the end of SDP.
•
Fixed this problem: A,B,C,D digits are dropped when dialing.
•
Fixed this problem: SPA9000 only sends $NOTIFY (SIP NOTIFY method) as NAT keep alive
messages for Line 1/2/3/4 regardless what is set in the <NAT Keep Alive Msg> parameter.

Firmware Version 5.1.6
Firmware Version 5.1.6
5.1.6 (SPA2102)
The caveats and features described in this section apply only to the SPA2102.
Resolved Caveats
The caveats resolved in this firmware release include the following:
•
When doing RTP packet loopback, the unit sends encapsulated RTP packets but also normal audio
packets with the same SSRC.
•
The unit does not use the same Authorization header fields in the ACK as in the corresponding
INVITE, per RFC 3261.
•
If <SIP Transport> is set to TCP or TLS, the unit might not send keepalive messages properly when
destination is $PROXY.
•
When <SIP Transport> is set to TCP or TLS, the unit does not include transport=tcp or transport=tls,
respectively in the Contact header URI in the 200 OK response to a REINVITE request.
New Features and Enhancements
New features and enhancements added in this firmware release include the following:
•
Removed Polarity Reversal from the “DTMF(Denmark)” caller-id method. Instead, a new
“DTMF(Denmark) With PR” caller-id method is added that behaves the same as the former
“DTMF(Denmark)” method.
•
The strict DTMF Tx mode works for AVT. Previously, it works only for SIP information. For the
SPA2100, the minimum duration for DTMF detection is as follows:
– Strict mode for AVT—70 ms
– Normal mode for AVT—40 ms
– Strict mode for SIP info—90 ms
– Normal mode for SIP info—50 ms
•
Added the IVR options 1910, 1920, 1911, and 1921 to check and set the SIP transport setting for
Line 1 and Line 2.
•
Accepts the %xx escape syntax in the <NAT Keep Alive Msg> parameter. For example, %0d%0a
is unescaped into \r\n (CRLF).
•
Allows each SIP message to be as large as 5119 bytes.
5.1.6a (PBX)
The caveats and features described in this section apply to the SPA9000/9000T.
Release Notes for Linksys SPA Firmware Release 5.x
Document Version 3.1
15
Firmware Version 5.1.6
Resolved Caveats
The caveats resolved in this firmware release include the following:
•
Should not detect off-hook during polarity reversal transients (during on-hook caller-id generation
for some regions); otherwise, the off-hook signal may be false because the loop current might flow
because of the transients.
•
SPA9000 does not pass 183 from an external ITSP to the calling PBX station.
New Features and Enhancements
New features and enhancements added in this firmware release include the following:
•
Added the <Phone DLG Refresh Intvl> parameter. If not zero, this parameter is the interval in
seconds at which the SPA9000 sends a SIP NOTIFY/ping event to each station that is currently
engaged in an external call. The default value is 0.
•
Removed Polarity Reversal from the “DTMF(Denmark)” caller-id method. Instead, a new
“DTMF(Denmark) With PR” caller-id method is added that behaves the same as the former
“DTMF(Denmark)” method.
Known Issues
The following is a known issue:
•
The inbound call does not hear a ringback when the call is transferred from AA to an internal
extension. To download workaround version 3.3.6, see the following URL:

Firmware Version 5e 5.1.5
Firmware Version 5e 5.1.5
5.1.5 (SPA2102)
The caveats and features described in this section apply to the SPA2102.
Resolved Caveats
The caveats resolved in this firmware release include the following:
•
_SIPTCP_ only—After backoff when TCP connect is rejected by the server, the default server port
always becomes 0, so re-connect always fails without attempting the TCP connect messages.
New Features and Enhancements
New features and enhancements added in this firmware release include the following:
•
Added the “dtmf detection tx mode” parameter with normal and strict settings. The default setting
is strict mode, for which the following are true:
– A DTMF digit requires an extra hold time after detection.
– The DTMF level threshold is raised to -20 dBm.
– For the SPA2100, the minimum duration threshold is 60 ms for AVT and 100 ms for SIP-INFO.
– For the SPA2102, the minimum duration threshold is 60 ms for AVT and 90 ms for SIP-INFO.
5.1.5 (GW)
The caveats described in this section, which are resolved in this release, apply to the SPA3102.
Resolved Caveats
The caveats resolved in this firmware release include the following:
•
_SIPTCP_ only—After backoff when TCP connect is rejected by the server, the default server port
always becomes 0, so re-connect always fails without attempting the TCP connect messages.
•
Line 1 fallback PSTN and ring-through does not work if either Line 1 or the PSTN line is set to use
TCP or TLS as the SIP transport.
•
If the keepalive message is not a valid $SIP-METHOD macro, the keepalive destination is
$PROXY, and REGISTER is enabled, the keepalive message is not sent to the last Register
destination.

Firmware Version 5.1.1
Firmware Version 5.1.1
Resolved Caveats
The caveats resolved in this firmware release include the following:
•
The DTMF detection for the SPA2102, SPA3102, and SPA9000T during conversations is too long;
calibrated to 60 ms for AVT and 90 ms for SIP-INFO.
•
Includes “replaces” in the Supported header in outbound SIP messages and accepts “replaces” in the
Require header in inbound SIP messages.
•
The NOTIFY request for a refer event during call transfer does not include the subscription-state
header that is required per RFC 3265.
•
If <NAT Keep Alive Msg> is not $PING, $NOTIFY, or $REGISTER), and <NAT Keep Alive Dest>

New Features and Enhancements
New features and enhancements added in this firmware release include the following:
•
Added the <Auth INVITE> option for Lines 1/2 to enable the challenging of incoming initial
INVITE requests.
•
Three parameters are added:
– <Reg Retry Random Delay>—Random delay range (in seconds) to add to <Register Retry
Intvl> when retrying REGISTER after a failure. The default is 0, which disables this feature.
– <Reg Retry Long Random Delay>—Random delay range (in seconds) to add to <Register Retry
Long Intvl> when retrying REGISTER after a failure. The default is 0, which disables this
feature.
– <Reg Retry Intvl Cap>—The maximum value to cap the exponential backoff retry delay (which
starts at <Register Retry Intvl> and doubles every retry). The default value is 0, which disables
the exponential backoff feature (that is, the error retry interval is always at <Register Retry
Intvl>). If this feature is enabled, <Reg Retry Random Delay> is added on top of the exponential
backoff delay value.
•
A new feature is added to re-validate the DHCP-assigned IP address when the application fails to
communicate to the peer.

5.1.0 (PBX)
The caveats and new features described in this section apply to the SPA9000 and SPA9000T.
Resolved Caveats
The caveats resolved in this firmware release include the following:
•
Sending the network ringback tone to a caller using G729 while another call is already using G729
causes a reboot. This is fixed by not sending the network ringback tone (using the 180 instead of the
183 response) if the negotiated codec is a low bit-rate codec. The caller in this case hears silence
instead of the ringback tone when an external call is transferred by the auto-attendant (AA) or a
phone to another phone.
•
Includes “replaces” in the Supported header in outbound SIP messages and accepts “replaces” in the
Require header in inbound SIP messages.

Firmware Version 5.1.0
New Features and Enhancements
New features and enhancements added in this firmware release include the following:
•
Added the “All+Self” option in <VMSP Bridge> to let the SPA9000 bridge external calls to the
voicemail server even when both the Internet telephony service provider (ITSP) and the voicemail
service provider (VMSP) are on the same line interface. Note that using the All option causes the
SPA9000 to bridge only when the ITSP/VMSP are on different line interfaces.
•
Added the <Auth INVITE> option for Lines 1/2 to enable the challenging of incoming initial
INVITE requests.
•
Three parameters are added:
– <Reg Retry Random Delay>—Random delay range (in seconds) to add to <Register Retry
