I followed the FAQ on this site to get a SIP trunk connected between an IP 500 V2 and an Asterisk system. I was able to get the SIP trunk up and running and I was able to dial an extension on the Asterisk side. I was even able to transfer the call from the IPO to the Asterisk extension. The issue is when I do this the CallerID is not retained (it shows on the Asterisk side as blank). The customer is insisting that we get this fixed and the Asterisk side is insisting they have other IPO people doing the same thing and can send the correct CallerID. I asked if the Asterisk side could ask one customer how they got it to work but of course they refuse to do it.
IP 500 V2
9.1.9
SIP trunk license 5 channels
Only sending from IPO to Asterisk (never other way)
Shortcode 1000/dial 3k1/1000/17 to get across SIP to Asterisk works fine even for transfer
I can not seem to wrap my brain around how to maintain the CallerID in this situation. Any and all help would be greatly appreciated.
The truth is just an excuse for lack of imagination.
