Configuring analog callback on 3620 w/ MICA modems (ACS 2.6)

All,

I'm trying to get callback via ACS to work on my 3620. The call negotiates, initiates call-back (or so it looks like from the logs) and then just sits there. The client never actually receives the callback from the router. I've got an analog callback script in place, I just can't sort out why its not working. I'm sure I've configured something incorrectly or left something out, and I'd appreciate your help.

Re: Configuring analog callback on 3620 w/ MICA modems (ACS 2.6)

you can see that the script "callbackanalog" is already started and dialed out and the mica modem is already went all the way to EC_NEGOTIATE that means that the two modems during callback already connected.

Now if the client modem have never received the inbound connection then where did the connection go? Make sure that the number reported in the

3d18h: Modem 1/9 Mica: received dialstring 000000000000

is the number which supposed to be called out during callback for that client modem. Call me have gone some where else. Just verify the number called back and its format. You can turn on "debug isdn q931" to see what numbers are being dialed at isdn layer too.
