Yes, there are all softphones (PC machines with old-fashioned headset & 
mic and smartphones running a sip client).

I'd rather do it by myself. For now though, I'd like to see whether what 
I want to achieve is possible in FreeSWITCH. I haven't yet made a 
decision what to use though - Asterisk or FreeSWITCH, it will all depend 
on whether I could set it up properly and "relatively" easy. Having said 
all that, as I developer with quite a bit of experience behind me, I am 
not afraid to delve in and get my hands dirty, if needed. I just want to 
make sure that what I want in terms of set up and functionality is possible.

I presume different profiles can "talk" to each other, right? In other 
words calls/media can be routed/transferred from one interface to 
another (eth1<->tun0 for example)?

This is what I am trying to figure out - do I rely entirely on 
FreeSWITCH (if not, what is expected of me to set up so that FreeSWITCH 
can do its job?), or do I have to do it all by myself with the kernel 
module helpers (sip, h323 etc) and ip/iptables?

RedHat is good, all I need is a decent .spec file - I'll do the rest 
myself, no problem.

One thing I seem to have forgotten from my newbie list of questions - I 
take it FreeSWITCH can do call-recording (in both directions) right? If 
so, how is this stored/implemented (I hope both ends are stored as a 
single sound file)? I would like all calls to be recorded as a matter of 
policy, so I do need this implemented if I am going to use FreeSWITCH.

Many thanks again.
