You're asking if a VoIP link could be used with traditional modems to do OOB management?

I'm pretty sure the answer is a flat no: any modems faster than 1200 bps
depend on phase change modulations that VoIP codecs can't begin to deal
with; FoIP is implemented by spoofing: the TA detects CNG tone, and spoofs
a datalink. 

I don't know of any TAs that will do that with regular data modems.
