Setting the duration seems to solve the problem for me.
<param name="default-dtmf-duration" value="800"/>

The rubix cube of rtp_bugs may help, I can almost bet IGNORE_DTMF_DURATION and GEN_ONE_GEN_ALL may be all you.

That is not a good thing. So, if we are using freeswitch and have intermittent audio issues with PSTN calls, I guess there is no real solution except to change the carrier ?

Some sonus settings are VERY specific to specific sonus firmware and will completely break talking to others.  In fact, for the same reasons, some versions of sonus firmware will break when talking to different versions of sonus firmware.

I am having similar issues with Sonus and occasional packet loss etc. I am using not the latest and greatest FS but was updated last Nov 2014.

 

The wiki states

“Note that the version of FreeSWITCH which has this patch auto-detects Sonus, so you don't need to configure anything”

 

Does it really apply *all* of the fixes for SONUS or only the DTMF fix.

 

I was considering using the below param tailored for Sonus bugs.Do these have any effect ? or are they deprecated ?

 

<param name="manual-rtp-bugs" value=" SONUS_SEND_INVALID_TIMESTAMP_2833

|SEND_LINEAR_TIMESTAMPS|START_SEQ_AT_ZERO|NEVER_SEND_MARKER|IGNORE_DTMF_DURATION| |GEN_ONE_GEN_ALL"/>

 

And clear the auto-detection param.

 

Thanks

Sharath

Aron its not that you're doing inband suppression, Sonus is buggy and if its in your media path it can cause lots of headaches.  Many carriers use Sonus, some as just SBC's and some that handle media.
