    Call Block

      Is there a way to block numbers in the Total Access 908?

          Yes,

           

          Here is an example:

           

          voice grouped-trunk VOIP

            trunk T01

            accept $ cost 0

            reject 12125551212

           

           

          This trunk will accept all calls except 12125551212.

            Kurttsc,

             

            Thanks for posting!  The Total Access 900 series does not support blocking calls from a SIP trunk to an voice user (FXS port).  If the inbound call reaches the internal switchboard with destination that matches a voice user number, identity, or alias, the unit will ring the associated port.  However, you may be able to block this call in the network or on the customer PBX.

             

            Thanks!

                David,

                   Would it be possible to use an HMR Ruleset that matches on the from header and then rewrites to the to header to an invalid number and set up the policy to run the rule on calls coming in on the sip trunk?  Just a thought.

                    John,

                     

                    Yes, that could work.  However, I would typically recommend that this type of feature be handled on the SIP server, SBC, or customer PBX.  If we use HMR to essentially "break" the valid call, it could have unexpected consequences on the network side.  I would be concerned about call loops or failover initiation on the network side if we were to respond with something like a 404 Not Found to a valid call. 

                     

                    Thanks!
