[SIPForum-discussion] Multiple DTMF events received for a single DTMF event

[Konstantin Bokarius]

Ashish - 

 

What do you mean by termination and what exactly was the resolution to your
problem?  Do you mean they matched the other SIP system's DTMF settings to
Asterisk?

Hi!!!,

I faced the same issue, when I was testing with one of my termination, at
that time, I was getting some weired dtmf before my actual DTMF string,
well, at that time when I called my termination they matched the DTMF used
(info, rfc2833 etc.) with my settings at asterisk and problem resolved. I am
not sure about this but this info may help you to steer your debugging in
right direction. 

Regards, 

Ashish

I have a call bridged through Asterisk to another SIP system.  Unless the
't' option in the Dial application is specified (this option is to allow the
called user to redirect the callee) each time a DTMF event is received by
Asterisk from the callee the called SIP system received 4-6 multiples of
that DTMF event.  So if the callee hit '16' on his keypad the receiving
system might receive '1111666666'.

 

When Asterisk dials another kind of SIP system I don't see this problem -
only when dialing a specific system (and that system's DTMF features cannot
be configured).

 

Has anyone experienced anything like this?
