The ITSP requires that we send ${itsp-registration-...@${itsp-domain} .
I have attached the firewall pcap. If you look at frame 8 of this pcap,
you will see that the from header contains exactly that. However, what
is interesting...is that the PAI header contains my personalized
callerid information in the format ${user's-caller-...@${your-sip-domain} .So...as far as I can tell, when the call rings through, the ITSP reads the 'From' header and passes that along as the caller ID information, because, from what I understand about SIP/SDP protocols the PAI is *not* passed for caller id, it is for informational purposes only...right?? I could have this backwards...I am new to this whole SIP thing, so please correct me if I am wrong. ------------------------------------------------------------------------ Heather L.
