CME SIP Trunk with VoIP Provider

[Thang Le]

Hi all,

Would you please give me a help about configuring SIP Trunk with a VoIP Provider like Pennytel on Cisco CME 9? I've searched around but no luck, thanks very much!

Thang,

You will need to speak to Pennytel and find out from them what you need to configure. Do you need to authenticate to their registrar servers? What IP address should you send your signalling traffic to? What sip port do they use? DO they require any other specific configurations...

In a normal/simple scenario a simple dial-peer pointing to their proxy server will do..So you  need to get all the facts and we can hel with the config
