Get DID from the to string

1

Hello,
I receive DIDs in the following form:
INVITE sip:XXXXXXXXXXX;tgrp=14;[email protected]:5060;user=phone SIP/2.0.
My freePBX cannot extract DID from this string. Is there any setting I can modify to work it correctly or I must write my own context to process the To strings?

The DID is read on the call event logging page as XXXXXXXXXX;tgrp=14;trunk-context=172.16.255.17

Try setting the context for your trunk to
from-pstn-toheader

Set a default Inbound Route and see what appears for the DID.

If it’s not usable, post a sample of the To: header on an incoming INVITE.

I set my context, the incoming calls are received OK, but now the problem is with outgoing calls (dial application). Should and can I modify the to headers, so I can include, for example, the tgrp and trunk-context switches?

You cannot modify From/To headers in such a manner. What format are they expecting for calls?

5

They have not told me the format yet. I tried to set the from field in the trunk settings with the trunk-context and tgrp switches, but that is not enough.

6

Your provider hasn’t told you the format of DIDs or any other specific settings like from user/domain or preferred CallerID method?

Then how can you even test outbound calls?

7

Everything used to work except redirecting with foreign caller ids. To fix this they decided to use trunk groups, and outbound calls now do not work. I think either they have not finished configuration settings or I need on my side to make modifications. So, I expect, tomorrow there will be further information.

So then there’s nothing that can be done until then. Got it.
