[asterisk-r2] [INTERDIGIT TIMEOUT]

Thu Aug 25 12:31:43 CDT 2011

Thanks by your answer Moises.

I have 2 E1s connected to a Siemens EMS 601 and 2E1s connected to the telco.

When somebody was trying to dial a pstn number from the siemens side, he/she
had to dial quickly, otherwise the call is attempted with incomplete DNIS.

I set  *timers.mf_back_cycle=15000* and now I can wait 15 seconds between
each dialed digit.  So, problem solved.

Now I'm facing another one.

I can't call Siemens operators.  The Siemens technician says the PBX sends a
B11 when trying to call an operator and this generates an Invalid
MultiFrequency Tone Error on Asterisk CLI.
I got an Invalid MultiFrequency Tone Error also when I try to call to a busy
extension on the siemens side.

This is the log of a call to a Siemens operator extension.
