    Adtran 924e PRI to SIP

    answerphone New Member

      Greetings,

       

      I know it is possible to use this device as a gateway from SIP to PRI, but what about the reverse?  We have legacy PRI's in the building and our new phone switch can only take SIP trunks (asterisk bases).  I saw a post about a sample configuration for this but was unsure if this would work with this model 924e.

       

      Is there a configuration that could work with this?  Our phone carrier is actually using 2 PRI's, so the config would need to reflect that.  I am having high hopes that this is possible.

       

      Thank you,

      Edward

            Add to Unified's configuration to prevent random ticking sounds and slanted faxes:
