asterisk users - Nov 2004 - How to configure the Asterisk server such that a FXS phone can talk to SIP client?

Hi,

Could you please help me!! I am trying to configure the Asterisk server.
I have a analog phone connected to a FXS port of a Cisco 3745 router. This
router is connected to a Asterisk server via Fast Ethernet interface. I am
trying to make a call from the analog phone to a SIP client. This SIP client is
registered to the Asterisk server.

Analog phone number: 999
SIP client : 202
Sip client IP address: 40.0.0.14

Here is a "sip debug" output for your reference: (Sorry that this
email is so long. Want to give you all possible information that I have.)

I always get a "Not Found" error. What am I doing wrong? Please let me
know if I can send you my sip.conf and extensions.conf files?
