[Freeswitch-users] transcoding GSM with a high ptime

I need to do a bit more work on this before I have enough information to submit a Jira but just on the off-chance anyone else has had this issue: We have handsets using GSM with 120ms ptime but when this gets transcoded to something else (for example 20ms PCMU) the resulting audio is choppy as though there was a timing error. We only experience this with GSM, 120ms packets to 20ms transcoding between other formats is fine. Has anyone else experienced this? I've experienced it on git-e7acd4d (our production kit) and f3c33c7 (due to become our next production kit) I'll continue to test it before submitting a Jira but I wanted to know if it was just us experiencing this.
