SNOM PA1+ Manual Config
First, you will need to create a manual extension through the Ring-U portal. You can create a manual extension by clicking: Configuration, then Extensions and at the bottom of the extensions page click the green Add Phone button:
After creating your extension, give it a name and an extension number. You will dial this extension number to initiate a page. The manual extension will automatically generate a password. You will use the extension number and password for Identity 1 in the next few steps:
In another tab, log into the SNOM PA1+ by typing in its IP address into the address bar. You will need to be on a network that can communicate with the device.
Choose Identity 1 on the left side of the screen. Account is the extension number for the manual extension you just created:
Click the NAT tab and set Keepalive interval to 15 and Number of Initial Keep-Alives on RTP port to 2.
Click the Advanced option on the left side of the screen, pick the SIP/RTP tab and page down to the bottom:
Enter a name for the paging group and its multicast address.
Note: The port number at the end of this multicast address corresponds to the group number you are configuring for paging. For example, this group is 502, so the port number is 2502, group 507 would be 2507. You can copy the full address directly by navigating in the portal to the group you are configuring and it will be listed in the top right where paging is enabled. See below:
Click Identity 1 again on the left side of the screen, then click the SIP/RTP tab. Add the multicast address and port to the Multicast relay address box:
Click apply and the paging group should be ready to use by dialing the extension number. To configure another group, repeat this process with another manual extension and use Identity 2 through 4 to configure it.
