[Freeswitch-users] advise to troubleshoot a call

Wed Apr 24 15:11:07 MSD 2013

Hi

The only "peer to peer" would be skype but she is not using it while on 
the phone and in any case that is only for messaging

I have a router with openwrt but never got the QOS to work. I tried to 
read about it and got scared :)

In any case I thought my link would be good enough.
