SIP Trunk to Teliax: chan_sip works, PJSIP outbound fails

So, I am setting up a new server, and connecting it to Teliax. I figured that I would use PJSIP for all extensions and trunks on this machine, as that’s the way of the future, but I am running in to an issue with making a SIP trunk work. Incoming calls work fine, but outbound calls are rejected with a “403 Forbidden” message. If I disable the PJSIP trunk and add a chan_sip trunk, everything works just fine.

Working chan_sip trunk:

Peer Details:
username=myuser
type=friend
secret=supersecretpw
qualify=yes
insecure=invite
host=hostname.domain.dom
fromdomain=hostname.domain.dom
dtmfmode=rfc2833
disallow=all
context=from-trunk
allow=ulaw

Register String: myuser:supersecretpw@hostname.domain.dom

As for the PJSIP trunk, I have set up the trunk name to be the same as the username (I think this could be avoided if I manually configured the AOR setting?). I also configured the settings in the UI:

General Tab:
Username: myuser
Secret:••••••••••••••••••••
Authentication: Outbound
Registration: Send
SIP Server: hostname.domain.dom
SIP Server Port:5060
Context: from-pstn
Transport: 0.0.0.0-udp

Advanced Tab:
From Domain: [My IP Address]

I have tried various combinations of different options in the advanced tab, such as Client URI, From User, etc, but I’m just throwing stuff at the wall and hoping something will stick. This is a (badly) obfuscated version of what I got from pjsip set logger on:

XXX.XXX.XXX.XXX is Teliax’s IP
YYY.YYY.YYY.YYY is my IP
2125551212 is the dialed number
6175551212 is my callerID

I could just fall back on the working chan_sip configuration, but that’ll eventually need to go away, so I really don’t want to do that, especially because this is a new install. I’m sure that there is some simple thing that I am missing, but I don’t know what it is. Any insight that someone might be able to provide would be much appreciated.

If you are using this as the From Domain in Chan_SIP why are you using this in PJSIP?

It’s the same setting for both of them. You need to have the proper From Domain in your PJSIP trunk not just your IP.


(Tom Rymes) #3

@BlazeStudios: Thank you! It’s super obvious, and I know that I tried it that way before, because I compared all of the settings side by side, and I swear that it didn’t work. Of course, now that I have embarrased myself by posting this thread, the PBX gods have made it work.

Once again, thank you!

It was just Schrodinger’s Route.
