Hi, we have a problem, when we try to register a T21p with Asterisk PBX

We put

User
Password
SIP server
Port 5060
but the register faill

The Yealink, replace a Phone cisco

I need to put a diferent configuration in my pbx or in the Yealink?
In phone side, just make sure that every register information are correctly filled.

Can you capture a pcap trace when registering. From it we can check the failure reason.
