Hello asterisk-users,
I'm currently investigating a problem related to the Transfer app and
DTMF tones via SipInfo.
My setup depends on:
Asterisk 1.2.10
Zaptel 1.2.8
libpri 1.2.3
Elmeg IP 290 (snom190)
Wildcard TE400 (E1)
The following dialplan is given:
exten => 555, 1, Transfer(554);
exten => 554, 1,Dial (SIP/tel3, 10, tT);
exten => 554, 2,Dial (Zap/g1/017123123123, 10, tT);
exten => 554, 3,Hangup();
If I dial 555 on my SIP phone it transfers to 554 and connecting me to
that zap channel.
Arriving there I'm not able to type ANY DTMF tones.
If the Transfer is skipped the DTMF tones are available. I've included
the SIP debugs to help you track the problem.
Greetings and many thanks in advance,
Michael Konietzny
