can bad static routes create havoc with an Avaya IP Office?

[573dawn]

Hi all, I have an Avaya IPO4 system that routes traffic across 3 T1 PTPs on Cisco 1720/21s to 3 remote locations.

One router, 192.168.0.200, connects 2 of the 3 back to the main site.

The other router, 192.168.0.199, connects the 3rd site.

A 3rd party brought in by my Avaya vendor had added
0.0.0.0 0.0.0.0 Null0 to the 192.168.0.200 router, and
0.0.0.0 0.0.0.0 192.168.0.200 to the 192.168.0.199 router.

We have had dropped call issues for quite a while now, and I THINK that maybe these routes were causing problems. I removed them both, as I have no reason to think that I have any routing loops, and in addition no reason to want traffic going from the main Avaya unit to 192.168.0.199 which would then try and send that traffic to 192.168.0.200.

It has been the site connected by 192.168.0.199 that has all of the problems.

Was this a sound decision?

Thanks, Dawn
