Extension CID instead of trunk/route CID on the called party

[Robert17]

Hello,

since ages I’ve renewed (complete new installation) my quite old freepbx system to Freepbx 17.
Since the source system was quite old (ver. 13.something) I didn’t transfer any settings and started from the scratch.
I also changed the trunk from chan_sip to chan_pjsip.
So far, so good.

The only issue I have is, that the extension CID doesn’t get transfered to the called phone. It is always the trunk numer displaed, even I haven’t it configured either at the trunk, nor at the oubound route.- the setting seems to come fromthe sipgate.de provider configuration.

I can see at the logs:

[2025-08-12 09:19:00] VERBOSE[341482][C-0000002a] pbx.c: Executing [s@macro-dialout-trunk:33] ExecIf("PJSIP/203-0000014e", "1?Set(CONNECTEDLINE(name,i)=CID:4922123456789)") in new stack
[2025-08-12 09:19:00] VERBOSE[341482][C-0000002a] pbx.c: Executing [s@macro-dialout-trunk:34] ExecIf("PJSIP/203-0000014e", "0?Set(CONNECTEDLINE(name,i)=CID:(Hidden)4922123456789)") in new stack

But I’ve absolute no glue from where the 2nd line comes.
Any idea..?

figured out my own solution - tested with a German (sipgate.de) trunk.

Edit extensions_custom.conf and add:

[macro-dialout-trunk-predial-hook]
exten => s,1,Noop(Entering user defined context macro-dialout-trunk-predial-hook in extensions_custom.conf)
exten => s,n,GoSub(func-set-sipheader,s,1(P-Preferred-Identity,sip:${CALLERID(number)}@sipconnect.sipgate.de))
exten => s,n,return()
