Sip trunk terminated by 1841, how on UC500 to failover to FXO?

Shiyue Cheng

Hi, I have a partner engineer at Verizon who asks if we can failover to FXO ports on the UC 520, when it is connected (by Ethernet) to an 1841 that terminates the SIP trunk? The 1841 is the actual device that terminates the SIP trunk and not the UC 520 (due to device approval for Verizon SIP trunking). Is there a command to associate the 1841's Ethernet interface and shut it down when it detects the serial interface (SIP trunk) is down? That way the UC 520 can failover to its FXO ports.

Perhaps there is another way? Thanks for any help/suggestions.

With CCA, you can have failover through the dial-peers configured automatically.  If the call fails on the SIP side, it will proceed with FXO.

Yes.  It is using the SIP messages, or lack there of, to failover to the PSTN lines.  This is done on the outbound dialing config screen in CCA.

Thanks Steven, so that works regardless of how the SIP trunk is actually terminated?
