If the caller hangs up the call, the call is ended on the caller side but the call stays up on the PABX side. After running a trace, I can see that there is no BYE message.
I cannot find any option in the SBC that could be blocking the BYE message.
I know it is not a carrier issue as it worked fine when the SIP trunk was connected directly to the PABX
If the PABX handset hangs up the call, then both legs hangup just fine.
