Adtran 908e responds with 501 method not Implemented

Hi All,

I am sending Register messages from our MiVoice Office 250 to one of our service provider through Adtran 908e. What I observed is MiVoice Office 250 is constructing Register messages as required by the service provider but Adtran is responding with 501 method not implemented.

Please find the below SIP messages. What could be the possible reason ?

Do you have sip transparent proxy enabled? A copy of the configuration with passwords and sensitive information redacted would be useful.

Re: Adtran 908e responds with 501 method not Implemented

These messages are standard responses when the ITSP is doing keep alives to keep the trunk active and check for availability of the Adtran.  If the trunk is up and working then these messages can be ignored.
