Hi,

I configured the PPP server on IP800, I have several external phones connected with the pptp connection.
When I make a call between an IP 222 connected by PPTP and an IP222 in the LAN, I have no sound from LAN to PPTP Phone.

My phone in the LAN (IP: 192.168.1.100) has a gateway 192.168.1.1 (the firewall)
My PPTP phone (IP: 192.168.1.70) has a gateway 192.168.1.10 (the IP800)
The problem of sound is probably a problem of gateway on the phone.


When I active "RTP Proxy" on IP800, no problem. But I don't want to activate the "RTP Proxy" because I have several MYPBX that use video!


Do you have a solution?

Thanks in advance!
