Endian FW Community 2.5.1 SIP issues

[Guest]

Hello All,

I have been having only one problem with SIP and my Endian firewall.  I occasionally get dropped calls from the SIP phones.  The VoIP server is in house connected directly to our modem(so phones go out and back in to talk to the server).  I have opened all SIP ports needed in and outbound:  TCP5060, TCP+UDP 1024-65535.  My VoIP vendor recommended disabling "generate ringback media" on the firewall.  I can't find this setting in Endian.  Has anyone had dropped call issues and resolved it?  If you need more info, please let me know.

Thanks
