SIP Trunking Service Configuration Guide
Optimum Business
Issue 2.0
Port 5060 must be forwarded to the address entered in Program 10-12-09.
Port 5060 is not used for remote terminals - ports 5070 and 5080 are used
instead. Port 5060 is only used for trunking so there are no issues with the
possible fraudulent usage of unauthorized remote attempts to register remote
terminals.
The ports used in Programs 84-26-02 and 84-26-03 must be forwarded to the
IP address entered in Program 84-26-01.
The RTP/RTCP ports are forwarded to avoid possible one-way conversation
which might occur on inbound calls. When forwarding the ports, the range for
each gateway must be set. The number of gateways to forward will depend on the
size of the IPLA.

Gateway 1 will require ports 10020-10051 forwarded.

Gateway 2 will require ports 10052-10083 forwarded.

Gateway 3 will require ports 10084-10115 forwarded.

Gateway 4 will require ports 10116-10147 forwarded.

Gateway 5 will require ports 10148-10179 forwarded.

Gateway 6 will require ports 10180-10211 forwarded.

Calling Party Information (Trunk)
Caller ID - In the Invite message there are two fields that can have caller ID. One
field is the “SIP From Address” and the other field is “SIP Display Info”. If both of
these fields are left blank the call will not complete.
Below is an example of a SIP Invite Message with outbound CID.
From “2142622000”<sip:test@172.16.0.100>
14-12-01 : SIP Register ID Setup for IP Trunks
On a per trunk basis, you can choose a SIP register ID of 0~31. If the ID is left to
0, the “SIP from Address” would not be assigned on a per trunk basis. If set to
1~31, it then looks at command 10-36-02 to populate the “SIP from Address” field.
14-12-02 : SIP Register ID Setup for IP Trunks
This is for SIP trunks to the provider for inbound purposes. If 10-28-06 (Trunk port
Binding) is enabled, inbound calls map to the trunk. If you want to create a hunt
group when trunk port binding is enabled, set multiple trunks to the same pilot and
then define that number in 10-36.
10-36-02 : SIP Trunk Registration Information
Per registration ID 1~31 you can assign what will be populated in the “SIP from
Address” field.

15-16-01 : SIP Register ID Setup for Extensions
Per station you can choose a SIP register ID of 1~31. If left blank the “SIP from
Address” would not be assigned on a per station basis. If assigned, it will look at
Program 10-36-02 to populate the “SIP from Address” field. This takes priority
over command 14-12-01.
10-28-04 : SIP System Information Setup – User ID
This is the default “Display Info” and “From Address” if either of these fields is
blank what is assigned in this command will be inserted. This setting has the
lowest priority and if any of the next commands are set they will be sent out
instead of this command.

the highest priority.
This program is used to assign the Calling Party Number for each extension
(Entries: 1~0, *, #). The assigned number is sent to the SIP Trunking Service
Provider when the caller places an outgoing call. If the Calling Party Number is
assigned by both Program 21-17 and 21-18/21-19, then the system uses the data
in Program 21-18/21-19. Do not use Program 21-13 for SIP. This entry must be a
10-digit DID associated with the SIP Trunking Service Provider Account. DID
numbers are provided by your SIP Trunking Service Provider Coordinator.

Dynamic Mode all extensions' Calling Party Numbers must be set to the Pilot DID.

Outbound calls will not work for extensions where the calling party number does not match
the Pilot DID.

Enabling DIDs for Outbound Caller-ID Appearance
To enable the use of DIDs for outbound Caller-ID appearance you must perform
two steps:
1.

STEP 1 - change from “Carrier D” to “Carrier B”.

STEP 2 - change the “Codec Maximum Audio Frame Size” to 20ms.
Go to the “10-29:SIP Server Information Setup” screen.
a
Select “Carrier B” for the “14 - SIP Carrier Choice” field. Note that this will allow the
PBX to use the DIDs configured for each extension’s caller ID from 21-19. See
“21-19:IP Trunk (SIP) Calling Party Number Setup for extensions”.
b
Uncheck the “16 – Register Sub Mode” field. THIS MUST BE DONE EVERY TIME
YOU CHANGE THE SIP CARRIER CHOICE.
c
Hit the Apply icon.
