Thanks for all the input!
To clarify:
I have already set this this system up using linux/win/mac IAX clients and
it works great. Reliability is very high (no failures within the 4 months
I've had it up) with my dedicated asterisk server running off my DSL
connection (QoS on with a linux router). If the asterisk server cannot
reach me via a VoIP connection, it fallsback to calling my cell phone
number. If the asterisk box fails for whatever reason, my VoIP provider has
a fallback number to dial as well. The asterisk server just has a VoIP
account for inbound and outbound calls, no analog lines are connected.
The cost benefit here would be the ability to accept a lower plan from your
cell provider (possibly data-only when 3G is available?), or even use a
prepaid service with the smartphone. I am currently using a per-minute
VoIP/POTS termination plan with no monthly fee, which works out to be much
cheaper with the lower cellular plan.
I have not wrote the application as of yet, I wanted to gauge interest for a
project like this. If I do write this application, I would like to
implement encryption along the way. In addition, I would set up an asterisk
box at our business location for testing within a larger userbase. The
reason I prefer to use a full asterisk system is the ability to integrate it
within our business.
I prefer IAX over SIP because it is NAT routeable, whereas SIP has many
issues with firewall traversal. In reality, the client should support both.
Keep it coming! :-)
