[asterisk-bugs] [JIRA] (ASTERISK-20975) DTMF issue with SIP trunk

[Michael L. Young (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=202138#comment-202138 ] 

Michael L. Young commented on ASTERISK-20975:
---------------------------------------------

Asterisk 1.8.8 is over a year old.  There have been quite a few fixes put in since then for DTMF.  Are you able to reproduce this on a newer version of Asterisk?

If you do produce this on a newer version of Asterisk, can you provide what number is being dialed so we know what digits are being missed.  Also, a full debug log would be helpful, https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information.

Thanks

> DTMF seems not work reliably for incoming calls through Skype Connect trunk.
> The system is installed from FreePBX distro. Asterisk version is 1.8.8.0
> There is a Skype connect trunk configured for LD calls. The problem is when users call a Skype number that leads to IVR, and try to reach any extension, Asterisk ignores DTMF tones.
> relaxdtmf=yes  
> DTMF mode is RFC2833 (as Skype recommends)
> jitterbuffer is set to yes
> and that's what I see in logs.
