Hi Friends,
 
I'm using OpenSER 0.9.5 and Mediaproxy together and it works okay, i've tried as conditions below ;
 
* Clients are behind ADSL Modem/Gateway/Routers, many of them,
* Their bandwidth is not lower then 512kbit (up) / 128kbit (down),
* I've tried with ATA's, Zyxel P2002, Zyxel P2000W, Zyxel P2602HW, LinkSys PAP2-NA, Cisco ATA186 and mostly i prefer g729,
* No sound problems or NAT problems,
* OpenSER is connected to PSTN gateway and it works well.
 
And for anyone interested in postpaid billing, i'm modifying original database since i have somethings to add it and corrected some stuff in it... You will be able to check current position of it, tomorrow, will post URL to list.. Everything is PHP...
 
Thanks,
Ozan
