I am setting up a Pipeline 85 to use ISDN to connect back to my MAX 2000 PRI. I can dial the number to the Max with a phone and I get the eerie sound like normal. However, from my 85 when it tries to connect it instantly disconnects the call. I verified the settings because I have used this scenario before. I am using CHAP as the auth method and have verified my passwords on both ends. I thought my SPIDS might be incorrect but when I choose atuo-spid they come up correctly. The switch type my telco is using is 5E. Are the 85's compatible with using this version of switch type? I do not see an option for it. I upgraded the device to version 8.0.x and still no luck. My WAN link isn't constantly blinking so I know it's configured correctly. The WAN LED comes one when it tries to dial then goes off when the router terminates the call. Anybody else use this same setup and have similar problems.
