History of Solved CTS Cases
The following list refers to open cases in the Change Tracking System 'CTS'.
This Build Series 2015-07-09
12454 Commands on EFM interface did not provide any help text
Two commands specific to the EFM interface in the mode “port dsl” did not provide help for its
parameters. These were the commands “service-mode” and “tcpam”, which require specific
values to be entered. But on pressing „TAB‟ or „?‟ no valuable help for these values was
provided. This is fixed now and the values for help are provided again.
12462 Fixed back-to-back codec negotiation when codec preference order was altered by peer
If a SmartNode was routing calls between two SIP capable devices, it tried to adapt the codec
preference order to each side, which could lead to incompatibility if the orders were different the
two peers.
Now the SmartNode respects the codec preference order of the peer side (the one sending the
200 OK with the supported codecs by both sides) and forwards it to the caller.
12463 Loosing memory when using PRACK with SIP
PRACK as a feature is used to set up reliable early media streams by using PRACK requests to
acknowledge the reception of provisional responses. In SIP call flows where the SmartNode
was the originator of the call and sending PRACK requests in reply to provisional responses it
did not release all the memory used for that call. This lead to crashes over time because
memory was running out, depending on the frequency of the calls using PRACK. This is fixed
now and calls involving PRACK do release all of the used memory from those calls.
12469 SIP stack upgrade to V4.2.14
SmartWare‟s SIP stack has been upgraded to V4.2.14.
Build Series 2015-05-11
12425 Fax detection during non-transcoded SIP-to-SIP calls
In some cases, it may be desired to detect fax or modem calls on the Smartnode. However, for
SIP to SIP scenarios, this was not possible when the Smartnode was not actively transcoding. If
both call-ends used the same codec, the Smartnode would release the DSP resources to
optimize performance but disabling the possibility to detect fax or modem (media) during the
call. A new command has been added to make this performance optimization configurable, so
that fax and modem can be detected even when not transcoding. See details in the New
configuration commands section.
12426 Better handling of failing EFM daughterboard upgrade
In case of a failing upgrade on an EFM daughterboard not enough information was displayed.
From now on, there will be more details available to identify the cause of a failed upgrade.
Rev. 1.00
12444 Control SDP announcement in provisional responses
A new command no early-media emit has been introduced which prevents sending of any SDP
announcement in provisional responses. The positive form with the auto option represents the
default behavior where provisional SDP announcement is done based on call properties. For
more details on the new command see the New configuration commands section Early Media.
12448 Digest Authorization scheme is now case-insensitive
There was an issue in the SIP registration process with authentication: the authorization header
was case-sensitive. If for instance the header was set to “DIGEST” (all caps), the Patton device
did not recognize the scheme and did not authorize the registration. This issue has been fixed.
Build Series 2015-03-17
12410 Add port option to spoofed commands in SIP gateway
It was possible to specify the global address to use in SIP requests with the spoofed NAT
address command. But this was lacking a way to specify the port to be used and therefore it
worked only for gateways using the default port. With adding the port option to the spoofed NAT
address command it is now working for gateways using a non-default port as well. See details
in the New configuration commands section.
12417 Send INVITEs to registrar
A new feature has been introduced which allows sending INVITE requests to the IP Address of
the registrar where a given identity is currently registered to. For this purpose the destination IP
address is forced to the detected registrar address independently of any URLs present in any
SIP header of the INVITE packet. For more details on the new command see the New
configuration commands section Force Destination.
12431 SNR and attenuation values for devices with ADSL interface
Now Signal-Noise Ratio, line attenuation and signal attenuation values can be read on Patton
devices with ADSL interface when executing the “show dsl all” command.
Build Series 2015-01-16
11932 Support for CAMA emergency E911 protocol
SmartWare can act as an E911 to SIP gateway. These means taking CAMA calls on FXS ports,
receiving and decoding the caller-ID and then forward it over SIP to the PSAP. SmartWare
currently supports two types of CAMA trunks, Tandem and Enhanced MF. The more traditional
Tandem trunks submit a 7/8 digits number whereas Enhanced MF trunks can submit 10/20
digits numbers to be able to cope with the new wireless phone technologies where emergency
calls are not coming from a fixed location.
The following CAMA trunk types are supported on the FXS ports:
Rev. 1.00
Tandem CAMA trunks (NENA-04-001), 7/8 digits
Enhanced MF trunks (NENA-03-002), 10/20 digits
For a detailed description please refer to the Software Configuration Guide for R6.7, available
12384 Tunneling of ISDN UUI1 information over SIP
SmartNodes have now the capability of translating User-to-User information from ISDN
networks to SIP and vice-versa. The used protocol on the SIP side is according to “draft-ietfcuss-sip-uui-isdn-11 - Interworking ISDN Call Control User Information with SIP”. Please refer
to the New configuration commands section for more details.
12411 Support for R2 to R2 call scenario
In case of a R2 to R2 call, the call terminations were connected too early and the backward
tones of the outbound call were heard on the inbound side. This is now fixed.
12414 Addition of MWI capability on FXS with battery-reversal
Analog phones connected to FXS ports can now be used to display Message-WaitingInformation based on the polarity of the provided battery voltage. The polarity is normal when
no messages are waiting. When messages are waiting the polarity is reversed back and forth
with an interval of 500ms. This feature was tested with a corded analog Cetis E100 Telephone.
Please refer to the New configuration commands section for more details.
Build Series 2014-11-17
12110 ISDN calls are now visible through SNMP
The number of connected, ongoing, and accumulated ISDN calls is now visible through SNMP,
listed per ISDN port. The new defined OIDs are:
Connected:<port number>
Ongoing:<port number>
Accumulated:<port number>
12403 Configuration of G.SHDSL card is correctly applied during first boot
When a SmartNode with a G.SHDSL daughter card was booting for the first time, the
configuration was not correctly applied. As the device has a mechanism to try to apply the
configuration shortly after a failure, the card was correctly configured during the second retry.
This resulted in an error message in the boot log. The configuration is now correctly applied to
the card during boot without any error message.
12405 Firmware upgrade through HTTP fixed
There was a problem when the HTTP client tried to parse the HTML webserver files. The parser
treated the HTML files as plain text, which caused the problem as the files are binary
compressed. This issue has been fixed.
Build Series 2014-09-15
12366 Extended REFER timer for call-diversion
Rev. 1.00
When making a call-diversion using SIP REFER mechanism, there was a timeout of 60s for the
call to be answered. The call transfer was being disconnected by the Patton Device if the actual
destination was not picking up within a minute. This timeout is now configurable.
12390 Accept 406 status code as fax failover trigger
SIP response code 406 is now accepted as trigger for Fax failover. If a RE-INVITE for T.38 is
sent to a remote gateway which is not T.38 capable that gateway can now respond with either
415, 488, 606 or 406 to force a failover to Fax Bypass transmission.
12398 PPPoE and VLAN configuration fixed for EFM SmartNodes
There was an issue when configuring a PPPoE session on the DSL port of EFM SmartNodes
(/2G or /4G models). The configuration was not applied to the “dsl 0 0” port but on the ”Ethernet
0 0” port. This is now fixed and the configuration is correctly applied to the DSL port.
12401 Early-media fix
In SIP to SIP calls scenarios the early-media was sometimes missing before the call was
connected. This is now fixed.
12402 SIP endpoints leak
When sending a SIP BYE or a CANCEL message and the peer did not follow the normal SIP
flow, it could have result to a memory leak. Now in case of abnormal SIP flow after a BYE or
CANCEL, then the call is correctly terminated to avoid any SIP endpoint leak.

TFTP may not work with certain TFTP servers, namely the ones that change the port number in the reply.
When using the SolarWinds TFTP server on the CD-ROM this problem will not occur.
With 10bT Ethernet ports, only the half duplex mode works. (With 10/100bT Ethernet ports, all
combinations work.)
The SolarWinds TFTP server version 2.2.0 (1999) does not correctly handle file sizes of n * 512 Bytes.
Use version 3.0.9 (2000) or higher.
The SIP penalty-box feature does not work with TCP. When the penalty box feature is enabled, the TCP
transport protocol must be disabled using the „no transport tcp‟ command in the SIP gateway
configuration mode.
Changing a call-progress tone has no effect. Adding a new call-progress tone and using it from the tone
set profile works however.
The Caller-ID message length on FXS hardware with Chip Revision numbers below V1.5 is restricted to
32 bytes. If the message is longer the message will be truncated. The FXS Chip Revision can be
displayed using the „show port fxs detail 5‟ CLI command.
When doing 'shutdown' and then 'no shutdown' on an ethernet port that is bound to an IP interface that
receives its IP address over DHCP, the IP interface does not renew the lease.
Using the command „terminal monitor-filter‟ with regular expressions on systems under heavy load can
cause a reboot.
The duration of an on-hook pulse declared as flash-hook has been raised from 20ms to 1000ms, to
cover the most country specific flash hook durations. Existing installations should not be affected, as all
on-hook pulses lower than 1000ms are declared as flash-hook, including the previous default of 20ms.
However, care should be taken in analog line extension applications, to make sure that the flash-hook
Rev. 1.00
event is allowed to be relayed over SIP or H.323. This can be achieved by disabling all local call
features in the fxs interface on context cs: no call-waiting, no additional-call-offering, no call-hold.
The internal timer configuration command is only able to execute commands that produce an immediate
result. Some commands that execute asynchronously cannot be executed by the timer. The following
commands (among others) cannot be executed by the timer:
copy any kind of files from or to a TFTP server
reload without the forced option
The command “no debug all” does not fully disable the ISDN debug logs. As soon as any other ISDN
debug monitor is enabled, all the ISDN monitors that were disabled by “no debug all” are re-enabled.
The codecs G.723 and G.729 cannot be used at the same time on all platforms, except on the
SmartNode 4960.
SmartNode 4960 Gigabit Ethernet does not properly work with Dell 2708 Gigabit Ethernet Switch. A
work-around is to configure 100Mbit.
Due to memory limitations it is not possible to download a software image to the SN4552 when two SIP
gateways are active.
On SN46xx units it can happen that there are more open phone calls requiring a DSP channel than
DSP channels are available. This leads to the situation where a phone connected on a bri port rings and
has no voice after the user picks it up. To limit the number of calls using DSP channels it is suggested
to create a limiter service where each call from and to a bri port has to pass. When the total number of
calls on the bri ports is limited to the number of DSP channels each call is going to have audio on
picking up.
On older SmartNodes the two debug monitors debug media-gateway rtp and debug call-control print out
incorrect RTCP jitter values.
The command „call-control call drop <call>‟ is not behaving as expected. It drops all calls but does not
completely teardown all internal structures. Consequently the call numbers of the dropped call cannot
Rev. 1.00
be used anymore for further calls after executing this command. The same is true for the “Drop all”
button on the web interface on the “Active Calls” tab of the Call-Router section.
The following configuration may create duplicate packets: If one physical ethernet port is bound to two
IP interfaces with different IP addresses and on both IP interfaces a SIP gateway is bound and some
static routes are configured, then the SIP gateways may receive duplicate UDP packets.

General Notes
Factory Configuration and Default Startup Configuration
The SmartNodes as delivered from the factory contain both a factory configuration and a default
startup configuration. While the factory configuration contains only basic IP connectivity settings, the
default startup configuration includes settings for most SmartWare functions. Note that if you press and
hold the system button (Reset) for 5 seconds the factory configuration is copied onto the startup
configuration (overwrite). The default startup config is then lost.
IP Addresses in the Factory Configuration
The factory configuration contains the following IP interfaces and address configurations bound by the
Ethernet ports 0/0 and 0/1.
interface eth0
ipaddress dhcp
mtu 1500
interface eth1
mtu 1500

How to Upgrade
1. You have the choice to upgrade to R6.T with or without the GUI functionality.
To upgrade to R6.T without the GUI functionality, enter the following command (telnet, console):
copy tftp://<tftp_server_address>/<server path>/b flash:
To upgrade to R6.T with the GUI functionality, enter the following command (telnet, console):
copy tftp://<tftp_server_address>/<server path>/bw flash:
2. Load Patton-specific settings (preferences), if available:
Extract the files „b_Patton_prefs‟ and „Patton.prefs‟ into the same directory on the TFTP-server.
copy tftp://<tftp_server_address>/<server path>/ b_Patton_prefs flash:
3. Reboot the SmartNode afterwards:

How to submit Trouble Reports
Patton makes every effort to ensure that the products achieve a supreme level of quality. However due to
the wealth of functionality and complexity of the products there remains a certain number of problems,
either pertaining to the Patton product or the interoperability with other vendor's products. The following
set of guidelines will help us in pinpointing the problem and accordingly find a solution to cure it.
Problem Description:
Add a description of the problem. If possible and applicable, include a diagram of the network
setup (with Microsoft tools).
Product Description:
When reporting a problem, always submit the product name, release and build number.
Example: SmartNode 4960 V1 R6.T Build 2015-07-09
This will help us in identifying the correct software version.
In the unlikely case of a suspected hardware problem also submit the serial number of the
SmartNode (s) and/or interface cards.
Running Configuration:
With the Command Line Interface command 'show running-configuration' you can display the
currently active configuration of the system (in a telnet and/or console session). When added to
the submitted trouble report, this will help us analyze the configuration and preclude possible
configuration problems.
Logs and Protocol Monitors:
Protocol traces contain a wealth of additional information, which may be very helpful in finding or at
least pinpointing the problem. Various protocol monitors with different levels of detail are an
integral part of SmartWare and can be started (in a telnet and/or console session) individually
('debug' command).
N.B.: In order to correlate the protocol monitors at the different levels in SmartWare (e.g. ISDN
layer3 and Session-Router monitors) run the monitors concurrently.
Network Traffic Traces:
In certain cases it may be helpful to have a trace of the traffic on the IP network in order to
inspect packet contents. Please use one of the following tools (supporting trace file formats
which our tools can read):
Ethereal (freeware;
