i have a Setup on a Raspberry Pi 2 with Asterisk 11.21.0 and FreePBX 13.0.79 from www.raspberry-asterisk.org. I’m using the Conference System and it is doing very well. My problem is the use of DTMF for the Conference Pin.
Mostly it is working without a problem, but in some cases, Asterisk doesn’t recognize that I am entering an pin at all. Ist always the same phone, where I tried it.
I tried to use inbound, rfc2833 and auto, but it’s always the same. If it worked correctly, the log says:
[2016-03-14 13:23:48] VERBOSE[C-0000000d] app_read.c: – User entered ‘1234’
[2016-03-14 13:24:14] VERBOSE[C-0000000e] app_read.c: – User entered nothing.
The rest of the log seems to be identically.
In all cases, when Asterisk doesn’t recognize the PIN, it asks several times to enter the conference pin, but it never recognizes any number until i hang up and dial again.
Any idea, what can be done? Upgrading to Asterisk 13?
Thank you in advance!
