SIPorxd - 7 VOIP cisco 7960 - States -

[Aderium]

When I look at the Diagnostics : States section I see that all the IP addresses of VOIP Cisco 7960 are connecting to the external Public IP address of the service provider to port UDP 5060, but only one of the has a connection type MULTIPLE:MULTIPLE

SIProxyd is on
LAN
WAN
5060
Enabled
RTP min 10000
RTP Max 20000

My out bound NAT is automatic and the following are the states with 3 phones plugged in [ same with all phone is ]

udp 71.23.154.3:5060 <- 192.168.132.148:5060         MULTIPLE:MULTIPLE
udp 192.168.25.148:5060 -> 71.23.154.3:5060 -> 71.23.155.9:5060         MULTIPLE:MULTIPLE

udp 71.23.155.9:5060 <- 192.168.25.142:5060                 NO_TRAFFIC:SINGLE
udp 192.168.25.142:5060 -> 71.23.155.9:5060                 SINGLE:NO_TRAFFIC

udp 71.23.155.9:5060 <- 192.168.25.244:5060                 NO_TRAFFIC:SINGLE
udp 192.168.25.244:5060 -> 71.23.155.9:506                 SINGLE:NO_TRAFFIC

It seems that only one phone is sending back the correct singal wich is Multiple:multiple

Is the Outbound Nating affecting this process ? I thought that is what the SIPProxd Server does no ?

Ok so I solved the issue,

It seems that at least for this office configuration changing the Outbound NAT to Manual solves the issue ….
Pfsense 1.2.2 will create the default automatic NAT and that will be a great starting point ...
