Yes, but doing so depends on the receiving device caring about your concept of carrier. There are several ways this is commonly done in the signaling; in the Acme Packet SBC, you'd use a sip-manipulation rule to modify the Request URI. So INVITE sip:12293160013 at 4.1.2.3;user=phone SIP/2.0 might need to become RFC4694... INVITE sip:12293160013;cic=0123 at 4.1.2.3;user=phone SIP/2.0 (Dialogic has a nice page about this: http://www.dialogic.com/webhelp/img1010/10.3.3er2/webhelp/Description/Interw...) or... INVITE sip:12293160013;cic=0123;csel=sub at 4.1.2.3;user=phone SIP/2.0 or, also not uncommon if the call is going into a US-based telephone switch configured for carrier-equal-access dialing: INVITE sip:101023412293160013 at 4.1.2.3;user=phone SIP/2.0 or, even, INVITE sip:12293160013 at 4.1.2.3;user=phone;dtg=0123 SIP/2.0 ...when the dtg URI parameter is mapped to a carrier. It really depends on what the receiving device can interpret. Mark R Lindsey, SMTS +1-229-316-0013 mark at ecg.co http://ecg.co/lindsey/

Is it possible to add a CIC code to an outgoing call on an Acme SBC?
