Xymphony_Programming_-_SIP_Basic_Settings

Basic settings for Session Initiation Protocol can be programmed with using Sip link in Homepage Ethernet paragraph.

The Sip link opens SIP voip settings page.

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.

Default value of Signalling port ToS is hex B8, which is suitable for most networks. Before modifying this parameter, consult your network administrator.

If the Telesis system is operating behind a NAT equipment with bindings but the NAT equipment fails to translate declared IP addresses in SIP messages sent, then Declare external IP address checkbox should be marked.

Unfortunately, there are numerous SIP devices in the market, which are sending SIP signaling packets with incorrect checksums. When Ignore checksum in signalling checkbox is marked, Telesis system ignores the checksum in received SIP signaling packets. If you notice incorrect checksums in received SIP signaling packets, mark this checkbox. Otherwise, leave it unmarked.

When OK button is clicked on, the parameters are stored into volatile memories but they are not activated. In order to activate the modified parameters, these should to stored into nonvolatile memories and then the system should be restarted again. To do this, first operate Save command in Homepage System paragraph and then operate Reboot command in Homepage Control Program paragraph.
