  • Connectivity after Outage

    Hey guys. Got a interesting situation at one of our customers locations. With have 7.5 Shoretel installed with 9 sites in it. Most of the sites are within one city but 2 are out of state. One of the locations network connectivity is a point to point T1 that has problems. Periodically the T1 goes down and then comes back up. Its AT&T provided span and its crappy cable. Anyway when the span comes back up the SG T1 switch can no longer see the two SG60's out at the remote site. Thus no DID calls are routed to it. The SG 60's are back up and they can dial 4 digit to all other ext's and to voicemail. Its just the calls inbound from the T1 to phones registered to those SG 60's at the remote site. It takes a reboot of the T1 switch at the HQ site for those switches to be able to see each other again. I know the obvious answer is to tell AT&T to fix the span but apparently that isn't an option. Question is when other links in this network go down and back up the switches all come back on line just fine. Its just this one site. 7.5 Build 12.15.8200.0
    Any thoughts?

      I remember reading something about ICMP Redirects causing problems when VPN connections drop and reconnect. Perhaps this is part of your problem.

      Here is a previous post related to that.

        This sounds promising. Gonna turn off the icmp redirects and see what we get. Thanks
