I am trying to get a cisco 819-4G on Verizon to act as a gateway for a small branch office.

I'd like it to route out Gi0 when at all possible, if GI0 is down go out cell connection.

I know once I get everything I can use IP SLA tracking for fail over but I can't seem to get the cell connection to work.

debug chat
dubug modem
debug ppp

All seem to output nothing.
GI0 internet connection works fine.

You need to send interesting traffic out the LTE interface and it'll bring itself up.

Check to see if the WAN light turns green when you do.

if not submit a "show version" and a "show cellular 0 all" to this thread.

That worked by modifying the dialer.
