[Freeswitch-users] jitter buffer effecting input callback in lua

[Michael Jerris]

There is no reason I can think of that would cause this.  Have you  
tried different phones to eliminate if it is an issue just with one  
type of phone?  Please open a bug on jira.freeswitch.org with a  
minimal script example to reproduce and details of the devices it has  
been reproduced with.
