Change Recording Frequency


I’ve been seeing that Monitor Application calls every 20 milliseconds to write a frame into a filestream. This is an attribute of the structure ast_frame, located in /include/frame.h.

I’d like to know how change this attribute or find the place where this structure is initialized.

Thanks so much.


I think you will find that this interval is set by the source. 20ms is the standard interval for VoIP and may well be that used by dahdi.

For SIP, you may be able to change it in sip.conf, but only if the remote side concurs.
