Title: 3300: Calling party number display for SIP trunk
Post by: handwritten on November 01, 2021, 08:43:25 AM

How can we display the calling party number for incoming calls on a SIP trunk? At the moment, the phone display shows the string in the Trunk Label form. We know that the calling party information is included in the P-asserted Identity header (and privacy:id has been removed). I've been digging through the Trunk Attributes, and the CoS settings, but nothing seems to work. Any advice would be greatly appreciated!

Try removing the trunk label. I have no idea why this would propagate to the endpoints by default, it's much more useful to admins as a documentation field.
Or maybe a COS option could achieve this.

I tried removing the label, but now the phone shows 'T1282 Calling'. This doesn't correspond to anything in the SIP header...

I suppose it's something related to your SIP Peer Profile.
Can you export your selected SIP Peer Profile and attach it here? I want to compare it with my own SIP Peer Profile.

Thanks imanm93 for offering to take a look. I have attached the SIP peer profile with a few redacted entries.

That CSV file has all our SIP peer profiles. The relevant one is 'SBC'.

I think it is COS related, check all COS values involved

Thanks for sharing.
Under Signaling and Header Manipulation change these parameters and do a test procedure:
Use Privacy: none > Set to NO
Use P-Asserted Identity Header > Set to No
Ignore Incoming Loose Routing Indication > Set to Yes

Thank you for the suggestions. However, no dice! In the absence of the privacy:none flag, the call shows up as 'PRIVATE CALLER' or something similar.

I suppose that's a good sign!
You can now check your CoS. Usually 'PRIVATE CALLER' refers to some configuration of CoS on your trunk service.
