Report Reserve UDP ports to prevent Signaling & Audio Problems in Windows-related Topics Posted November 4, 2009 Listed below is a registry key that will prevent windows from using UDP ports in thesame range that pbxnsip requires for operation. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ ReservedPorts= 5060-5061 10000-12000 Separate values for ReservedPorts using enter to goto next line. You may change reserved UDP port numbers to whatever ports above 1024 are required to operate pbxnsip in your environment. In the sample above the first line is for inbound sip on 5060 thru 5061 and RTP media using ports 10000 thru 12000. Note to clarify this Registry edit: You are not adding a new key to HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ You are just adding a Multi-string Value called ReservedPorts (do not include the = symbol in the name).
