Hello All, I have never setup SIP trunking before so I have a question. I have CS1000M with SIP trunking to 1000B's already setup. We are trying to setup a DEMO for a Cisco Call Mangr. We want to test SIP trunking through the 1000M to make OB calls. Can I use the existing SIP trunk and if so what informtion do I have to give my Cisco guy so he can properly setup his end?
