asterisk users - Nov 2006 - call from cisco router to asterisk gets auto attendant

Folks,

I have a NEC 2400 pbx(non-voip) behind a Cisco 3725, connected via 
standard wic-t1 card.  The NEC needs to call two different asterisk 
servers with 4 digits.  I have two way calling working with the one * box, 
but the other is perplexing me.

Here's the layout

* <--> Cisco 2811(192.168.13.1) <--> 1.54 point to point <- Cisco
3725(192.168.8.1)<-> NEC 2400.

The * has 5xxx extensions and the Nec has 1xxx and 2xxx extensions.  The * 
can call me at 1621 just fine.  When I call any 5xxx extension, I get the 
main greeting.  To make it even more confusing, the * is set up so that 
the 1xxx and 2xxx extensions go through the 2811 router.  When I call the 
*, it identifies the calls as going through the 3725 router. 

The * can not dial 1xxx@192.168.8.1.  I believe this has to do with a 
routing issue due to a WAN aggregator box we are using, to be replaced by 
a 3mb circuit, soon.  The * has to dial 1xxx@192.168.13.1.  It then gets 
transferred to the 3725 router's virtual interface at 192.168.100.44, 
which binds h323 calls to the interface for QoS purposes.

Here's what I have on the sip conf.
