Interesting. Are both of you on the Vector /Sonus network? I know for a fact Sonus switches can do what I'm asking. so I'm not sure why they wouldn't choose to use that feature.

L3 has told me that the only option that they have is the hard set 25 second timer with BNA. They have also told me that they do not support rerouting on 503's. As for the BNAO settings, I was told they had attempted to implement a better solution but it did not work well and so they are back to the process of evaluating alternate methods Peter Fabian | Senior Voice Engineer | Telesphere | P: 4803857059 | F: 4803857079 On Wed, Sep 1, 2010 at 1:27 PM, Alex Balashov <abalashov at evaristesys.com> wrote: They should be able to fail over on a 503. But not a 603, for the reason that 6xx-class errors are semantically different. On 09/01/2010 03:01 PM, Geoff Mina wrote: I am currently setting up Level3 as a provider of SIP Toll-Free services. I am hearing from my account team that they don't have any option other than their BusyNoAnswer option to failover from one SIP IP (on my side) to another. If I send back a 486 or there is a timeout they can failover to a second trunk. Unfortunately, they can't decouple the 486 and timeout scenarios. and that doesn't work, because 486 is a normal non-error condition on my network and I wouldn't want the call to be re-presented to another location just because the first location sent a BUSY. I have asked them if they can failover on 5XX errors or internally generated 408, but they seem to think they are unable to do anything like this. Anyone have any experience with Level3 in this scenario?
