what’s the pb ??

I don’t see and error, or even a warning message. There is no problem.

The only time you might have a problem with this message is if the console is being flooded with it.

incompatilbe frame i think the problem with codec or tranformation to this codec

It is a codec mismatch, but such events are normal during certain transitions, which is why they are not reported as even a warning.

By the way, the correct forum for support questions is Asterisk Support.

thanks i will try to find solution

Trying to find a solution for something that isn’t a problem would be a waste of your time.
