Hello,
We are trying to figure this one out. We hooked up 4 ISDN lines to our Cisco 3640 router and when we try to make an analog call or even try dialing the number with a phone to hear what happens, we get a busy signal. We set up all the required parameters and tested an ISDN to ISDN call and had success, but not with an analog call. Any ideas to point us in the right direction? We have the latest IOS for the box, all the necessary cards, etc. Thanks for any help,
Matt

You need a digital modems in 3640 to terminate the analog call over isdn line..Pl. make aure that you have that in 3640..After that you need to have "isdn incoming-voice modem" inder the interface serial x:23 (d channel) to punt the voice/analog call over to modem..Here is the link which have sample config for that
http://www.cisco.com/warp/public/793/access_dial/5300.html
config will be the same for 3640 too.
Now if it still dosen't work, need to know the following debug
debug isdn q931
debug modem
debug modem csm
Also need running config too..Tejal

Thanks for the response. We do have the digital modems installed (just got those yesterday), but are still getting busy signals. Attached is our config, do you see anything out of the ordinary? These are four seperate ISDN lines. Not a T1. Thanks, Matt

The config looks OK...We need to know that the analog call is even forwarded over bri line to the router (3600) or not..Need to see the following debug now for a analog call dialin over BRI line.
debug isdn q931
debug modem
debug modem csm
debug ppp negotiation

Also there is a sample config along with troubleshooting info for your refereance..
