By factory default, SIP UDP signaling port is 5060, which is the well known port number stated in RFC documents. Changing this number may cause some routing equipment fail to deliver messages properly.
However, if desired, SIP UDP signaling port can be modified to another. To do this, click on SIP link in Homepage Ethernet paragraph.
The SIP link opens SIP voip settings page.
Edit the Sip UDP Signalling port textbox for the desired port number and then click on OK button. Be aware that when OK button is clicked in SIP voip settings page, modified parameters are stored into volatile memories but they are not activated. In order to activate the new parameters, these should to stored into nonvolatile memories and then the system should be restarted again.
If there are public (outside) SIP users, NAT should be programmed such that the UDP port (set in SIP voip settings page) is forwarded to the IP address of the Telesis system.
