Hi all.

 

Using DNS and SRV records for failover scenario (see attached file with screenshots and config files). Phones are all Polycom VVX310 with 5.4.3.2036 firmware version.

Phones should register via UDP in normal mode and when main SBC server fails, should register to secondary SBC server via TCP.  This is not working. We are getting the following messages when the primary SBC is OOS:

0613100925|sip  |4|00|Failed to connect to [10.25.226.3:0] : Error[Bad file descriptor]
 
Would appreciate any ideas/help.
 
TIA

Hello John,

welcome to the Polycom Community.

A working failover scenario is this configuration:

 

<failover voIpProt.server.1.address="sip.test" 
	voIpProt.server.1.retryTimeOut="500" 
	voIpProt.server.1.retryMaxCount="3" 
	voIpProt.SIP.tcpFastFailover="1" 
	voIpProt.SIP.authOptimizedInFailover="1" 
	voIpProt.SIP.failoverOn503Response="1" 
	voipProt.server.1.address="sip.test" 
	voipProt.server.1.port="0"
	voipProt.server.1.transport="DNSnaptr" 
	voipProt.server.1.failOver.reRegisterOn="1" 
	voipProt.server.1.failOver.onlySignalWithRegistered="1" 
	voipProt.server.1.failOver.failBack.mode="newRequests" 
	voipProt.server.1.failOver.failBack.timeout="600" 
	voipProt.server.1.failOver.failRegistrationOn="1" /

Please replace the sip.test with your DNS entry.

 

The voipProt.server.1.failOver.failBack.mode="newRequests" can be changed to "duration" in order for the voipProt.server.1.failOver.failBack.timeout="600" to come into play.

 

Using an SBC simply swap with voIpProt.SIP.outboundProxy.failOver
