[asterisk-users] Step-by-Step Asterisk and Cisco 1760 Help

[Jimmy Ezell]

I am up to post 5 on my step-by-step but I hit a bit of a snag and so far my searches have failed me, I hope someone can help.  (By the way, I added an asterisk index for quick navigation on the blog http://qvlweb.blogspot.com/2009/04/asterisk-pbx-install-index.html.) 

Here is the snag and I am hoping for a little help from the collective. Inbound I have 2 different numbers. I can call in on both of them at the same time and have two inbound concurrent calls going.  The problem is with outbound calls.  The first call goes out fine but the second call fails with a busy error.  So it looks like it is not failing over to the second line (which is what I expected the 1760 to do) and I am not sure if this is a Cisco setting or an Asterisk setting (or both).  I played with the Cisco setting, whichever line I set to preference 1 works but the preference 2 line does not pick up if line 1 is busy.
----See details below (asterisk console / sip.conf / extensions.conf / 1760 config)---
