Summary:                    Extension state change random delay
Description: 
asterisk-1.4.20-rc3
Grandstream GXP-2000 is registered as 1100 and subscribed to receive
changes about extensions states. 
SIP/1101 is Linksys 942
SIP/1102 is SjPhone.
I've also set notifyringing=yes.

1102 calls 1101. 1101 sends RINGING but asterisk sends NOTIFY to
Grandstream with 3 sec delay. You can see (log is attached) that RINGING
was at 19:11:27 and NOTIFY is sent at 19:11:30.
Later when 1101 answers you can see that device state is changed 9 seconds
after call have been established (19:11:50] DEBUG[24559] devicestate.c:
Changing state for SIP/1102-09551818 - state 4 (Invalid))
When call is over asterisk changes state for one of the extensions almost
instantly but there is 20 seconds delay for 1102 (19:12:20).
Please help to debug this problem.

corruptor, PTorres:  have either of you been able to test this fix yet? 
1.4.22 should have this fix, if you'd like to download and try that.
