Hi everyone, i have a dtmf issue in my CS1000. I am able to dial the DISA number from outside using an E1. But when i try to dial any local extension seems like the PBX i still hearing the tone... but when i dial the voicemail using the call pilot the dtmf is recognized, so...seems like the incoming dtfm using the E1 in the pbx is working.....any idea why DISA number doesn't hear the dtmf?. This is the DISA configuration
