I have been trying to configure the Mediatrix 3532DG to be able to accept SIP outbound PSTN call requests and inbound PSTN to SIP call requests. I have been successful in doing the SIP to PSTN routing with one exception. I am not getting disconnect supervision from the Siemens HiCom PBX toward the Mediatrix gateway when I disconnect a call at the Siemens HiCom end. The SIP phone remains in the call and will only drop it when I disconnect from the SIP phone. I am using NI2 profile on the PRI.
I have had absolutely no success getting a call from PSTN to a SIP phone. I have tried everythig I can think of to no avail.
Is there anyone out there who has figured this out? HELP!! (please)
