 |
|
Hi,
After I call the external number successfully, I’m able to receive DTMF from the softphone but the PSTN’s DTMF doesn’t work.
I am able to change the mute status during a conference from the same PSTN.
I had a look at: http://wiki.freeswitch.org/wiki/Dtmf_troubleshooting but it didn’t help.
I have:
<action application="bind_meta_app" data="3 ab s execute_extension::att_xfer XML features"/>
on the Local_Extension and on my SIP_PROVIDER extension, both at sofia/default
Any ideas?

We definitely don't want to assume anything, so I have to ask the
obvious questions:
who is the provider?
are the DTMFs in-band or RFC2833?
Any chance you can turn on full debugging and see if there are any clues?
Thanks!

My experience is, it can depend on the PSTN provider.
I had problems with Sonus systems (see your SIP Invite message), there
is a workaround in the wiki, but it didn't help in all my cases.
I also have tested the start_dtmf application for additonal dtmf inband
detection which helped in some cases.
I also tried <param name="pass-rfc2833" value="false"/> which didn't
help in my cases + blocks routing of DTMFs through freeswitch.
Best regards
