Summary:                    Big latency (up to 3 sec) when call waiting enabled
Description: 
I've installed backported chan_mobile latest trunk into asterisk 1.4 and it
working well except one issue. When I am using any phone having call
waiting indication (Sony Ericsson K750, SE K320i, Nokia 6021, Samsung E530)
voice lag appears for incoming traffic (from B-party to asterisk), no
difference if call is incoming or outgoing.

I have modified chan_mobile.c to disable callwaiting indication and sound
lag disappeared. Does that means problem inside chan_mobile ?

---------------------------------------------------------------------- 
This error appears to be caused because of the way chan_mobile handles
audio data.  Currently chan_mobile only reads audio from the phone when it
writes audio to the phone.  I am working on a fix.
