I tried to setup a PSTN Trunk for a SwyxConnect 1722 (which is identical to Lancom 1722). Although i tried several settings, i was not able to register the Trunk. I checked with the embedded Trace functionality of the SwyxConnect the SIP packets and noticed that Pbxnsip returned 404 not found.

 

Following you find configuration information and the trace - any idea what is wrong?

 

Pbxsnip does have the ip address 15.137.40.40 and the SwyxConnect 1722 15.137.40.2.

 

The trunk settings in pbxnsip are:

Type : SIP Gateway

Direction : Inbound and Outbound

Account : pbxnsip

Domain: 15.137.40.40

Username: pbxnsip

Password : test

Outbound Proxy : 15.137.40.2

 

The trunk settings in swyxconnect are:

Mode : Gateway

Provider Name : PBXNSIP

SIP domain/realm : 15.137.40.40

Registrar : 15.137.40.40

Outbound Proxy : 15.137.40.40

Port : 5060

SIP-ID/user : pbxnsip

Password : test

 

Here you see a part of the trace file:

Couple of things -

1. You do not need to register a "SIP Gateway trunk". Only "SIP Registration" trunks need to be registered. If you want the trunk to be registered, change the trunk type to be "SIP Registration".

2. For the trunk settings on the PBX, the "domain" and the "outbound proxy" have to be same (unless the SwyxConnect server instructs you otherwise)

 

Most of the information about the trunks is in http://kiwi.pbxnsip.com/index.php/Trunk_Settings (I could not find the pbxnsipsupport site page for this B) )

You cannot register a trunk to the PBX (you can register a trunk from the PBX to an external registrar). You can register only a extension. Now sure if that makes sense here; but this is worth a try. Otherwise, I would just use the gateway mode of the trunk and use the outbound proxy on the gateway.
