[Freeswitch-users] jitter buffer during bridge call

[Michael Jerris]

Without a debug log with sip trace, no… could be different ptimes on each leg?

For example I have some calls sent via two different gateways with almost same jitter and using route A I have breaks in voice using the second one it's fine. If I send via route A without jitter quality is clear. Once you put some jitter sucks. We started to have this problem once we upgraded from FS 1.2 to 1.6 and only noticed difference is this jitter.
