      SIP 183 not sent on receipt of ISDN Progress Message


      Description:

      When configured with a user role PRI, if the local exchange sent progress indicator #2 (PI2) to indicate the presence of inband audible ringback on a SIP to PRI call, a 183 Session Progress with SDP was not sent on the SIP call leg.

       

      Software Resolution: 

      An AOS R11.3.0 hotfix is being developed by ADTRAN.  Upon release of the hotfix, the firmware will be made available on ADTRAN’s website and a new software notification will be sent out.
