[Freeswitch-users] freeswitch on ipsec

[sibu]

Dear Freeswitch-Users/Developers

I am new to this  list and freeswitch.

I would like to know if anyone has tried freeswitch with an ipsec VPN such as 
openswan or strongswan and what were/should-be the  settings (eg transport-
mode, tunnel-mode etc), results  and  requirements vis a vis cpu-power, 
network-speed etc etc

all hints and suggestions welcomed
thanks in advance
