I think your problem is probably with the codec. Asterisk made a change a few versions back on the allow command and removed the disallow command. ---

Actually it not just the codecs, I have done the registration. The trunk is registered but still getting the following error. ERROR[582228]: res\_pjsip\_outbound\_authenticator\_digest.c:450 digest\_create\_request\_with\_auth: Host: ‘SERVER IP HERE:5060’: There were no auth ids available. and when I try to make call between 2 softphones that are registered using the lines, the call gets disconnect exaclty after 32s. It would be of great help if anyone can share a screenshot of the lines and the trunk configrations and I can use it according to my use. ---

Hello, If your SIP trunk won’t REGISTER until you make an outbound call (INVITE,401,INVITE), consider using “line = yes” in your registration trunk tab. I saw this behavior starting 22.X version (don’t remember which one) ![WAZO LINE](https://global.discourse-cdn.com/free1/uploads/wazo_platform/original/1X/86ebe20f2a3fb5e6d3da52868320783d64ec4d0c.png) Wazo will send REGISTER packets with this option. Does it solve your issue ? ---

In your SDP, the IP address is private, so if your are natted you need to configure correctly the Nat. Please check out documentation for the Nat. ---

I don’t see any information for your outgoing call. Line = yes is actually for multi-tenant in general for wazo, it just permit to have a line id in the registration to permit to find the good information of the invite from your sip provider. It’s not always supported. Have you created the rules for an outgoing calls via your sip provider? ---

Finally got the issue sorted, both outbound and inbound is working fine. Thank you so much for the support.
