Hello,
looking at your chat script, I think you might be missing a space. Make sure it looks like this:
chat-script lte "" "AT!CALL1" TIMEOUT 20 "OK"
or use the one you originally configured:
chat-script lte "" "AT!CALL" TIMEOUT 60 "OK"
Make sure there is a space between lte and the quotes:
lte ""
06-18-2017 01:28 PM
Hello,
try to remove the 'OK' from your chat script:
chat-script lte"" "AT!CALL" TIMEOUT 60
or try and 'offload' the cellular configuration to a dialer:
chat-script lte"" "AT!CALL" TIMEOUT 60 "OK"

Hello,
'Broadband' actually seems to be the correct AT&T APN. Either way, try the chat script below:
chat-script lte"" "AT!CALL1" TIMEOUT 20 "OK"

The debug output shows that the source of the ping is 192.168.1.100.
Add the following to your access list 2:
access-list 2 permit 192.168.1.0 0.0.0.255
06-18-2017 04:22 PM
Your profile is inactive. I noticed the APN is called 'Broadband'. Check with your ISP if that is the correct APN. If not edit the profile through the 'controller' command.
06-19-2017 05:40 AM
Thanks Paul-- all they provided was an APN IP-- how is that inserted?
06-19-2017 06:48 AM
Hello,
you might not need that. Try:
Router#cell 0 lte profile create 1
Did they provide CHAP username and password ?
