Can I have more than one SIP device in the same network?


What local SIP port do I use when more than 1 SIP device is in use?


A well designed router will be able to cope with use of the same local SIP port 5060 but most residential routers cannot. Depending on the device, this port is usually called SIP port or local SIP port and needs to be adjusted to reflect a different port number per device line. You can start at 5060 and work your way up using even number, skipping odd. For example you have 1 PAP2, 1 SPA and 1 Xten. Allow the PAP2 to use 5060-5062, change the ports on the SPA to 5064-5066 and assign the Xten SIP port 5068.
