I ´ve 2 PRI E1 connected to asterisk with PSTN and a siemens PBX connected to each end.
When I call from siemens PBX through asterisk to the PSTN and got the call established I try to dial an extension.
Unfortunately I hear the DMTF tones duplicate and then my call is transferred to whatever extension but the one I dialed.
Any help would be appreciated!!
