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 


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 ?
