Unique source port for outgoing sip trunk

[mbylica]

1. Brekeke Product Name and Version:
Brekeke SIP Server, Version 3.6.3.0 Standard

2. Java version:
1.7.0_101

3. OS type and the version:
Linux centos 6.9

4. UA (phone), gateway or other hardware/software involved:
doesn't matter

5. Your problem:
I am using BSS Standard as a kind of traffic concentrator.
There are several incoming sip trunks already configured as well as one outgoing.
I wonder if i could differentiate those incoming sip trunks by using unique source ports when sending packets out.
In other words:
- incoming sip trunk 1 -> outgoing sip trunk with BSS source port 6001
- incoming sip trunk 2 -> outgoing sip trunk with BSS source port 6002
- incoming sip trunk 3 -> outgoing sip trunk with BSS source port 6003
...
From header modification within Deployment Patterns is not enough.
SIP packet must be really sent from 600x BSS source port towards outgoing is trunk IP.

Do you have any idea of how to achieve my goal ?

Maciej.

There is no way to define SIP source port of BSS. It is always same as the listening port (5060 in the default).

We know there are such needs and it is in TODO.
