I have a xcast sip trunk that the customer wants the originating caller when a call is twinned. I have gone thru the threads tried using the system send originating caller id and using all options on the SIP tab. I se the caller id coming in. How do i get it to show going out? The sip provider say I have reverse caller id enabled? Any Ideas. Thanks in advance!
 
I have dealt with this too and it can vary by provider. You see if they have any type of install guide. I played around with various providers, never had a lot of luck, both my AVAYA distributors really didn't have any solutions. There are a few config notes on the knowledgebase, but not for all providers. Some have passed AVAYA testing, others have not. I would try pulling any install aid you can and tweaking one item at a time.

I may revisit this over the next week or two. If I learn anything, I'll add it to this thread.

Good luck.
 
Check your invite out - see what number is in the FROM and the PAI and if you sent the originating number there. Ask the provider what they permit and if they're changing it in their PSTN by replacing numbers not on your trunk (like a cell) with your BTN or something.
 
Perhaps they also need the Diversion Header set. Or they want to have P Preferred Identity what is supported from R10.
 
As said it depends on the provider.
With our provider it is quite simple, in the SIP line URI we set all contact fields with a *.
Then in ARS I create a shortcode with the numeber of the twinned cell phone and the telefonnumber to send to the line it the cellphonenumber with SS added at the end.

Then the origintors CLI will be send to the cellphone.
If a internal user dials user or the cellphonenumber number then the internal users telephone number is send.
