Hi All, I am stuck and hoping someone here can help.
Here is the situation. I have 10 SIP phones Polycom IP320's on a internal 10.0.0.x net. These phones then get dhcp from the pfsense 1.2-RELEASE box. Then out a cable modem to the phone provider. The Problem. I can only get one phone to work. The first phone that boots works, then remaining phones don't. When I say they don't work, they boot fine, get Ip information but I get no dial tone and I cannot make inbound or outbound calls. The phone that boot first works perfectly. I have tried all the various NAT tweaks I can think of like enabling static port and AON, nothing works same issue. I read : "SIP Limitation - By default, all TCP and UDP traffic other than SIP and IPsec gets the source port rewritten. More information on this can be found in the static port documentation. Because this source port rewriting is how pf tracks which internal IP made the connection to the given external server, and most all SIP traffic uses the same source port, only one SIP device can connect simultaneously to a single server on the Internet. Unless your SIP devices can operate with source port rewriting (most can't), you cannot use multiple phones with a single outside server without using a dedicated public IP per device. The sipproxd package will provide a work around for this issue, and is currently under development." OK, forget playing with rules/nat. I have installed siproxd and been digging through that documentation and testing with no luck. This is where I am, anyone have a working siproxd.conf that would be similar to my topology? Any pointers? Thanks, Lee
