Call from one site to another site thru inta-company trunk and then call forward


(Rdkerns) #1

So here’s my issue. I have two PBX’s SITE A and SITE B.

When one employee in SITE A Calls another Employee in Site B it works fine. But when Employee in Site B has their find me follow me turned on the call to the Find Me/Follow Me destination fails. In this case the destination is a cellphone. If an employee in site b calls the same employee in site B the find me follow me works fine.

Site to site PJSIP trunks do not send a valid caller ID out when a call forwards.

Even if you have the force route CID checked. I complained about this a few weeks ago or so.

I haven’t had the free time to debug the call flow.

There’s a technique in this post that addresses this use case: What is the best way to connect multiple FreePBX together?

The idea is to encode the external CallerID of the dialing extension in a custom header, and then extract it again on the pstn leg of the call. The linked post uses IAX, but the same could be done with SIP as well.

My orginal test case of this was using IAX with the same results.

And the custom context using the predial hook?


(Rdkerns) #6

I have not tried that yet. Am not quite sure how to add that,


(Itzik) #7

You need to add it in extensions_custom.conf

Well, How about that. Added that code to the extensions.conf on both sides. Placed the test call and I saw it route thru and go out the outbound trunk to the cellphone.

Thank you so much.
