Change SIP Gateway port

[albert-g]

I have two sip-trunks from one provider, on my PBX, and there is some issues with simultaneous work, and my SIP provider advises to set different ports on every sip-trunk, but I cant find such setting on gateway. Can someone point how should change this port?

The SIP port used by your gateway is the port specified in the external SIP profile. The only way you could have different ports per gateway (without introducing a proxy like OpenSIPs etc.) would be to set up multiple external SIP profiles.

Thanks Adrian,
I suspected the same. But, by looking for good practice, is it ok to have "ext. sip profile" per gateway?

I would argue that it is not good practice. I guess it would be fine and not too difficult to manage if you only had a very small number of gateways.

I would ask why the SIP provider needs to see different ports, there really should be no need. If your gateways connect by registration, the SIP provider should be able to differentiate between your gateways by their contact record:

sip:gw+b396770d-c35e-4870-b993-f4fc0bb2a7db@xxx.yyy.xyz.zzz:5080
sip:gw+7be7a198-7a28-4e5f-8318-0a77be0eccbb@xxx.yyy.xyz.zzz:5080
