TA900 Registering every 5 seconds even though expiry timer/grant is 60 seconds

Jump to solution

We have noticed that many of our deployed TA900s are registering every 5 seconds even though the expiration timer/grant is 60 seconds. Any ideas what may be causing this behavior?

by default the registrar default value is 300 seconds which is more than your expire time of 60 seconds so the adtran sets it to 5 second, the minimum.  You will need to change the registrar threshold absolute command.

for example it you want it be every 45 seconds then chane it to "registrar threshold absolute 15" then the countdown starts at 45 seconds.  Let me know if you have questions.

Here is default settings on a sip trunk:

#sh run voice trunk verbose

voice trunk T01 type sip

  ...

  registrar threshold absolute 300

  registrar expire-time 3600

Is this an either/or with the register threshold percentage command?

correct, you can use either absolute or percentage. You just need to select which one based on your needs. Absolute is easy math! 😃  if you set to 15, then 60-15 is 45.  😃
