No DTMF received from PSTN when using bind_meta_app during bridge between softphone ext 1000 and PSTN.
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! -MC
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 Peter Shahal Hazan schrieb:
