Sip Trunk Drops when Public Ip address renews

[edlee321]

Avaya IP500v2 R9.1.6

My Sip trunk goes down and does not come back up when Public Ip addresses renews a new address.

The only way i can fix this is to restart the IP office, is there any way for the system to detect the new address?

I have Stun server setup and set to run on Startup which should "When selected, the system will rerun STUN discovery whenever the system is rebooted or connection failure to the SIP server occurs."

But how come it did not notice the connection failure?

It does notice the connection failure but it has no way of knowing what has caused it. No business should be running on a dynamic IP on their Internet connection, so it's an issue that doesn't need to be addressed by Avaya as it's not being used in the correct environment, that's the actual problem

Thank you for your recommendation for going the Static IP route, but this does not really make the system resilient in the case of dual wan routers with failover. In the case of one of your providers going down, Avaya should have a process where it checks for new public IP after a selected amount of time.

You should use trunks that register every minute or so, that way it fails over just fine, no need to use STUN in most cases then, if your trunks need STUN you need better trunks or a good SIP ALG in the mix (most suck). But where it's secured by IP then the provider does the failover between addresses not you and you still can't use dynamic addresses.

Failover between multi WANs is nothing to do with them being on dynamic IPs or your initial question, no matter which way you slice it that shouldn't ever be the case

my sip provider does not need STUN, i think i set it up to get remote worker going

Avaya is a business system and I really don't know any business that has a dynamic IP address except the cheap ones that want all to work without spending money, including installations.
I have a static IP address at my home as well btw. so expecting a system to fix all the shortcomings that someone may discover is ridiculous.

SIP resiliency is done with 2 SIP trunks to 2 separate registrars provided by your SIP provider, one uses the first Internet connection while the fail-over uses the second Internet connection with 2 routers not a dual WAN router because you have again a single point of failure.
We do that for customers but if they are not shedding out the money for a static IP address I doubt that they want to pay for that.

i guess i am not the target audience for the ip office, i got the system free from a friend who switched to cisco, and i programmed the system myself.

It is literally the only system that can do contact closure while you are on an active line (coming from Avaya Partner)

But still Dynamic IP is still very prevalent in Small Office Networks. Maybe you guys only get contracts with large companies.

You should ask your ISP what it costs to get a static IP (I pay $4/month) that will solve all your problems.
