DTMF problem

[K.]

Hello !

I have the problem with the DTMF tone. When I make a call between 2 cell phones, I press the number in one phone, but the other phone cannot hear any dtmf tone at all. But from the log file I have attached here, it seem like the base station can detect the dtmf tone. Any way to fix this problem?

Thank you

DTMF forward to MS is not implemented.

Hello marian,

Thank you for your answer. I still don't know how to get this work. I have tried to configure the regexroute.conf : .*tonedetect_out=yes, but still cannot get the dtmf work.
Can you guide me a bit?

You may try to generate inband dtmf:
Catch chan.dtmf message, and attach a tonegen source to indicated peerid.
See:
http://docs.yate.ro/wiki/Chan.masquerade
http://docs.yate.ro/wiki/Tonegen#Override_data_source (override=tone/dtmf/handled_digit_in_chan_dtmf)
http://docs.yate.ro/wiki/Chan.attach

Bottom line
Send a chan.masquerade with message 'chan.attach' to peerid taken from handled chan.dtmf to attach a tone generator for received DTMF.

Hi marian,

Sorry for my ignorance, but I don't know how to generate the dtmf tone using Tonegen module. From reading the yate documents, do I need to use regex to generate the tone, or I need to do the configuration in tonegen.conf? Can you give me some example? I don't quit understand that.

You may try to following (not tested):

regexroute.conf:

[extra]
chan.dtmf=

[chan.dtmf]
${peerid}^ybts/=enqueue chan.masquerade;id=${peerid};message=chan.attach;override=tone/dtmfstr/${text}

Hello marian !

Thank you for your responding. Your code is working like magic!! I've been trying so hard to figure this out.
I will keep working on my yatebts. And will get back here soon if I have any question.

Cheers !
