I am needing to be able to disable call diversion or redirection Q.931 messages on outgoing ISDN NI2 calls from the TA. We are running into issues when a SIP call contains a diversion header, it passes that information onto the PBX and we get a reject message from the PBX unable to decipher the redirect info. Is there a way to disable call redirection messagines out from the TA? I am unable to control the SIP side from generating the diversion messages into the TA. The line in red is what we want to disable, it contains the SIP diversion information.
Below is debug from the TA:
