		<description>Hi Guys,

In this moment, I have installed Elastix-1.1-8-11ago2008.iso (with Asterisk 1.4.19) + astunicall-1.4.19-0.1.tar.gz

Asterisk is integrated with unicall successfully:

		<description>Hi Moy , 

Since i moved the asterisk to another box everything is working fine. Just some times i geting this kind of errors :

[Sep  4 17:21:23] NOTICE[4776]: chan_unicall.c:2516 handle_uc_event: Unicall/1 event Dialing
[Sep  4 17:21:23] NOTICE[4776]: chan_unicall.c:1912 unicall_exception: Exception on 17, channel 1
[Sep  4 17:21:40] NOTICE[4776]: chan_unicall.c:2516 handle_uc_event: Unicall/1 event Protocol failure
[Sep  4 17:21:40] ERROR[4776]: chan_unicall.c:2520 handle_uc_event: Unicall/1 protocol error. Cause 32769
[Sep  4 17:21:40] WARNING[4776]: app_dial.c:743 wait_for_answer: Unable to forward voice or dtmf
