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 ?

---------------------------------------------------------------------- 
I have not been able to reproduce any of those problems.  I do see some of
the unknown connection handle errors in my logs, but this probably occurs
at hangup when asterisk closes the SCO link.  It should not cause any
problems.  I have not seen any of the other errors.

The errors from problems 1 and 3 appear to be unrelated to asterisk,
although I am not 100% sure about that.  Problem 2 could be asterisk
related, but in my testing I have not seen it.
