Hi Attila, your patch more one time work without problems thank you again. Regarding this email let me check other problem with you. I have a asterisk box between a TDM Switch and a Cisco Gateway, using SS7 to TDM and ISDN to CISCO TDM<----SS7--->ASTERISK<---ISDN---> CISCO The call come from SS7 side and asterisk forward this call to ISDN. The cisco gateway plays a message in PROCEEDING. This message ask the user to put some digits. The calling side listen the message but when he put the digits the ISDN side don't receive the DTMF. I make a dahdi_monitor in SS7 channel and in ISDN channel. In the SS7 I can listen the audio and the dtmf and in ISDN side I don't listen the DTMF only the audio I don't know why asterisk don't foward the audio received on SS7 side before the ANM during the early media. Do you know anything about this ?
