Hello all,
We ran into some issues. The P’Asserted Identity that we are sending from our PBX to our carriers is not reaching the end destination. What could be the possible reason for it?
We had set everything right as it should be in the PBX dial plan and extensions. Please advise.
Thanks
If you’re actually sending it (you haven’t shown a log), then your carriers.
Talk to your carrier. In most cases carriers accept any callerID from other carriers, not from endusers. From endusers you normally only accept the customers own numbers.
I would suggest you check with your carrier, that you are actually allowed to send the CID you’re trying to send, and if so, what format they expect. Some carriers require numbers with country code, some requires a + before the contry code, some does not. If I’m not mistaken E.164 does not specify the requirement for a prefix, and is a common format used all around the world.

Well, take this with care: in France since 6 weeks is Stir shaken implemented and it already give case where operator is sending prefix+E164 which seems allowed in rules.
In Denmark, that’s not yet the case, and our interface agreement with upstream carriers, specifies the format to send. Can’t be changed without changing the agreement. 
But point was, you need to make sure you know what format your carrier uses and expects you to use.
