908e running A4-09-00-E sending registrations every 5 seconds

Jump to solution

We have a few 908s running A4-09-00-E that are sending registrations every 3-5 seconds. The messaging is below. The 908 requests an expiration of 3600 seconds and our SBC responds with 300 seconds. We have dozens of 908s deployed which respects the 300 second timer from our SBC. Is there a configuration element I'm missing that is required in A4-09?

gmccurdy,

Thanks for posting!  In current firmware, if the received expire time is equal to or less than our default registration threshold (300 seconds), the result is the 5 second registration renewal you observed on your unit.  You will need to modify the registration threshold to a number that is less that the expire time given from the registrar.  For example, I would add the following to your SIP trunk configuration.

voice trunk T01 type SIP  

  registrar threshold absolute 30

This command tells the unit to renew the registration 30 seconds prior to the expiration.  The result should be that your registrations will only happen every 270 seconds.

Thanks!

David
