If modem to RS232 is what OP meant. Then obviously he can do this with OOB
ETH also. Just buy modem with ethernet port.

I'd need this in hundreds of pops, I'm not going to build second
non-revenue generating network just to get OOB. I'm going to each pop check
what I can get, which does not use my network. Sometimes it's ADSL,
cablemodem, ISDN, 3G, WLAN maybe even PSTN.

Today:
Router_RS232 - ConsoleServer - Cisco CPE (DMVPN+IPSEC) ---random_access
Tomorrow
Router OOB - Cisco CPE(DMVPN+IPSEC) ---random_access

I'm not changing my access at all. I'm removing devices, I'm gaining
ability to send images. I'm gaining ability to fix box when control-plane
is fucked up.

What ever access you have, it won't stop working.


And people who cry 'oh my analog PSTN modem never breaks, cisco ISR will'.
Availability of OOB network is irrelevant, you maybe need it long-term 5min
per device per year. So as long as it is up then, you're golden.
Rest of the year, have your nagios SSH into the OOB ETH every 5min, and
raise alarm if shit is broken, then fix the broken shit.
