Remote Aastra 6731i won't stay registered


(Mvogel4949) #1

I don’t do a lot of work with Aastra phones but I’ve got a remote 6731i phone that will register for a minute or two and then drop off. There are Grandstream and Yealink phones behind the firewall with no problems. The phone can call out but soon can’t receive calls. Am I missing some NAT setting within the phone? Any Aastra help would be greatly appreciated. I’m running FreePBX14 and asterisk 13 if that matters.

what channel driver is it using and is it using the latest firmware ?

two things ive done in the past that have helped:

  1. try changing the local sip port for the phone … something like 5062
    or
  2. try changing the transport to TCP

ps - are you configuring by hand or with EPM ?

In addition to Chris’ suggestions, you may want to check the value for SIP registration expiration/period. You may want to try a setting of 2 minutes if it’s something higher. Or, compare it to what you have set on the phones that don’t have the issue. It’s possible that the nat tunnel closes, and re-registration is not happening often enough.
