What about having the capability to override the jitterbuffer settings 
from the dialplan?

At that point, you know both where you're coming from and will generally 
have a good idea of where you're about to go.

Something along the lines of: SetJitterBuffer(none|incoming|outgoing|both)

I can see this getting tricky in the case of transfers, but it might 
work well enough to solve things for most people, most of the time. If 
this function isn't used, the JB would use the default scheme dependant 
on channel jitter capabilities.

This would likely need the JB moved to ast_read() as KPF mentioned a 
couple of messages back before it would work.

Regards,
    Nic.
