NetVanta 3430 phone registration issues

Jump to solution

Greetings everyone,

I have NetVanta 3430 router connected to T1 and few IP phones connecting to asterisk PBX in the cloud behind it.

I'm switching to new PBX and the issue I encountered is that with new PBX I can register one phone and it will work fine, but if I add second phone it registers and within few minutes becomes unreachable.

I ruled out issue with PBX by registering phones from different location.

Attached is config with some settings removed for security.

jayh, sorry for getting back so late.

The suggested settings did not work.

Phones register registers and within minute unregistered itself.
