Hi I have problem with make call from office communicator to pstn. call is office communicator->ocs -> mediation server ->Brekeke PBX -> FXO gateway ->PSTN. by my setting, i am using two stage dialing: so i need to dial to PSTN first, after i hear the dial tone from PSTN I need to dial PSTN number which i want to reach, but office cmmunicator cannot dial twice at one call. Is there any way I could dial the number when OC is connected to PSTN?
