Vonage SIP on IPO

[Stengrad]

I have a preferred edition that I'm trying to get Vonage SIP connected to. They have no white papers on configuring for their service and their support wasn't any real help at all. Anyone have a system working with Vonage? Thanks in advance.

I tried to do a Vonage SIP trunk once, it didn't go well at all, they couldn't get it working, I think they are OK for home service but not for business.

Well, the customer currently has a Toshiba system that we are replacing with existing Vonage SIP Service. Why can't this stuff be standardized... ugh...

it is standardized, just with 1000 variables that different SIP providers use...

I think if you know the ITSP IP, ports, protocol and if they can handle Nat traversal or not. Registering by IP or with credentials Then you can configure it on IPO

I finally got with a level of tech support that made a difference at Vonage. It appears that the original tech gave me incorrect domain, and credential info. I had to figure out how to navigate the existing toshiba system to determine what was going on, and also verified with vonage. Now it seems that inbound calls give a busy around every hour or so. I have adjusted session timer method/timers, and also the registration expire timer. Any ideas what may be causing this?

This is Avaya IP office Forum. Not sure if someone can help you with Toshiba system here!

Yes I am aware of that. They had an existing Toshiba system. I replaced with IPO. Hence the reference to "preferred" edition in the initial comment.

Oh My bad, I thought you were looking for help to navigate toshiba system. Anyway, How is the network topology configured in LAN tab? Do you have keep alive enabled on that interface?
run a monitor trace and post it here pls.

I have seen the issue you are talking about with Versature sip trunks. In that case the timer on the versatile side was set to 60 minutes. Way too long, but not the only issue.
It that case the trunk would time out, and have to re-register. Unfortunately the DNS was taking too long and the a time out would be sent.

The trunk would eventually come back up on it's own, but in the meantime the users would get waiting for line presented on the phone... outbound of coarse. Assuming a busy signal on inbound.

One "bad" workaround was to manually take down and bring back up the trunk in SSA. This requires eyes on the trunk at all times. This helped keep the business running during troubleshooting.

Is it possible for you to use IP addresses instead of domains? If you getting the same DNS timeouts I had, that help.

Check with Vonage on what their timers are set to. Should to be more than 5 minutes. 60 may be fine for residential service, not adequate for business.

At the end of the day, I switched to DIDww.com sip trunks. No problems since.

I really need to get better on following up with resolutions... It ended up being an issue with the provider not giving me the proper IP information, AND credentials.
