Hi Tommy, Try removing the InternalNetworks line, and setting H245Routed=1 If that doesn't help, do a trace to see if GK is telling the endpoints to send audio to it. --Stewart ----- Original Message ----- From: "gnugkmail gnugkmail" <gnugkmail@xxxxxxxxx> To: <openh323gk-users@xxxxxxxxxxxxxxxxxxxxx> Sent: Thursday, July 21, 2005 4:53 AM Subject: Problem of Gnugk with proxy model. Hi all, My OS is fedora 3. I run the GNUGK 2.2 with proxy model. Fedora have two NIC(192.168.1.254 and 192.168.10.254). Two endpoits registered with GK. Two endpoints are distributed in the two networks. Fedora does not use ip_forword. So GK can ping Two endpoits. Two endpoints can not ping each other. One endpoint can call another successfully. But can not hear voice. Following is my proxy.ini. Please tell me what's wrong with the ini file. Thanks for any idea.
