Feedback: 3CX do not update public IP in SIP VIA Header automatically

[Boran Danismanlik]

Helle there,

Since we are running various hotlines in our operation, alternate internet connection is a must in case of a disconnectivity in the main connection. Rare, but it happens. Therefore we are using a firewall with active gateway routing to sense and switch to the alternate connection in case of a trouble. When the firewall swtiches to the alternate connection, we are able to accept inbound calls without any problem. But the outbound calls rejected by SIP provider with the following error in 3CX:

• Call or Registration to 0xx0605xxx7@(Ln.10006@0xx6526xxx0) has failed. 217.xxx.xxx.25 replied: 403 Forbidden-Source Endpoint Lookup Failed; from IP:217.xxx.xxx.25:5060

The SIP provider tracked this error on their side, then they mentioned that the IP in the VIA Header is not updated, still appears as the IP of the offline connection.


Then we have checked on our side and we realised out that the IP in the 3CX/SIP Trunk/Options/Put Public IP in SIP VIA Header still shows the offline IP eventhough the Public IP updated in the Dashboard. So we need to update manually the IP in the Options menu for every single SIP trunk. Because of that, the firewall's automatic routing does not make sense.

Please consider this issue as a feedback and please update this issue in the next release.

This option is a manual configuration and it will not auto-update of the ip is changed.

Thank you for the quick reply.
Isn't it possible to switch it automatically? Isn't there a plan for it? It should not be a big issue for the development team.

This is regarding a generic provider which is not supported. At the moment i don;t think this will change.

In that case, my suggestion would be to push the Turkish distributor of 3CX to cooperate with local SIP suppliers more proactively. There are only 2 approved service suppliers in 3CX SIP trunk list eventhough there are many active suppliers.
