NetVanta 3430 phone registration issues

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.

Re: NetVanta 3430 phone registration issues

jayh, sorry for getting back so late.

The suggested settings did not work.

Phones register registers and within minute unregistered itself.
