How to configure server failover with Obihai (and Poly 4xx) ATAs and IP Phones

[Liptonbrisk]

(OutboundProxy should be left blank with Freephoneline. There is no separate OutboundProxy server.)



1. Dial ***1. Enter the IP address you hear into a web browser. Login. Default username and password is "admin" (without the quotation marks).

2. i) Navigate to Router Configuration-->WAN Settings-->Local DNS Records for Obihai ATAs with routers (ex. OBi202)

a) For OBi200/300/2182 or Obihai devices without a built-in router, navigate to System Management–-->WAN Settings-->Local DNS Records)

b) For line 1 (presuming this is a blank line . . . just choose a blank line), enter

"voip2.freephoneline.ca={voip.freephoneline.ca:5060,3},{voip2.freephoneline.ca:5060,1},{voip4.freephoneline.ca:6060,2}" (without the quotation marks)

In this example voip2.freephoneline.ca:5060 (1) is being given priority. If there's no response on voip2.freephoneline.ca:5060 (1), then the Obihai device will attempt to register with voip4.freephoneline.ca:6060 (2), and if there's no response from that server, the OBi202 finally attempts to register with voip.freephoneline.ca:5060 (3).

I'm choosing voip2.freephoneline.ca:5060 as the primary proxy (SIP) server here because voip.freephoneline.ca tends to have the most problems recently.

Make the primary server (1) what you're defining (what's before the equal sign on the left). So if you want primary server (1) to be voip4.freephoneline.ca instead, then use "voip4.freephoneline.ca={voip.freephoneline.ca:5060,3},{voip2.freephoneline.ca:5060,2},{voip4.freephoneline.ca:6060,1}" without the quotation marks.


3. Click "Submit".

4. Navigate to Service Providers-->ITSP Profile used for FPL-->SIP->

a) change ProxyServer to voip2.freephoneline.ca (this needs to be what's before the equal sign). If you want the primary server (1) to be voip4.freephoneline.ca, then enter voip4.freephoneline.ca for ProxyServer.
b) change ProxyServerPort to 5060
If you want the primary server (1) to be voip4.freephoneline.ca, then use 6060 for ProxyServerPort. Otherwise, use 5060. That matters in some scenarios where the ATA or IP Phone boots up before the router finishes booting up.



5. Enable/check X_ProxyServerRedundancy (you will have to uncheck the default box). This setting is needed so that server failover works.

6. Set X_CheckPrimaryFallbackInterval to 7200 seconds (ATA will check to see if voip2.freephoneline.ca:5060 will work after 2 hours if it wasn't working; this will allow enough time for a temporary IP ban to clear as well on the primary proxy server, and then the ATA will register on the primary proxy server, voip2.freephoneline.ca:5060, in the first example, again).

7. Click submit.

8. Reboot ATA.
