Hi All, I have a client using an asterisk server for them to use my sip proxy, what I did was add a trunk on their asteriks with a local extension from my SER sip proxy. Can I also just do a prefix ID for them instead of trunk? Meaning when they send me a call they should prefix it with e.g 1234# so I will identify that it came from that client, and how can I account that? TIA Regards Nhadie ________________________________________________ Message sent using UebiMiau 2.7
