Avaya IP Office sip trunks 1

[ritzy1978]

First time poster long time reader. I've been doing Avaya systems for many years since Nortel sold to them.

Hoping someone can help.

I have around 30 IP Office system running version 10.0 to 11.1. Of various versions in between.

They all run the same sip trunk provider and same sip trunk settings. All have LAN to local LAN to access system only.
WAN direct to router with dedicated internet.

Randomly around 1or2 months the IPO locks up.

When I say locks up we can access the router remotely and can't ping the Avaya WAN port.
We can access the Avaya via the LAN port and in system system status can't ping the router either.
If I put a managed switch in between the Avaya WAN port and router and lockup happens I can ping that from router but not from Avaya.

If I reboot router nothing changes. I have to reboot the Avaya and everything comes back fine.

I'm at a loss and need help.

Let me know any other setting you may need..

Which address did you setup on the IPO's wan port? (I hope it's not the public ip address)

If the IPO is locked up, can you check if there are any IP adresses black listed?

What is the duplex setting of the routers port connected to the IPO wan port? Make sure it's auto-neg.

And please, use a SBC.

Hi Okkie26,

Thanks for replying.

The WAN port goes the the router directly which has dedicated internet and is dedicated for VoIP.

The router has port forwarding for SIP ports to the SIP trunk provider only.

It works perfect till the Avaya issue comes present.

I didn't think of the blacklisting. How long does that stay active if triggered?

Both Router end and IPO are auto neg.

Thanks.

If the IP was blacklisted would it disappear after a reboot?
