Hi! How would the TDM interworking work? Look at 'Figure 1: Overview of Operation' and assume this:
- Call SIP->PSTN The callee is in the PSTN/TDM world and proxy 2 acts as a gateway. In this case the callee would never send a SUBSCRIBE. If there is no authentication/authorization for the call the gateway may opt to subscribe to the user? - Call PSTN->SIP The caller is on the TDM side and proxy 1 acts as a PSTN to SIP gateway. The callee sends the SUBSCRIBE which ends up at the edge on proxy 1. What should the proxy do? a) Respond on behalf of the caller b) do not support the Dialog event package and respond with 489 to the SUBSCRIBE c) do some magic based on information conveyed on the TDM side?
