Hi
Since upgrading to MCD 4.1 (10.1.0.69_1), I have been having intermittent drop-outs on my E1. I upgraded the software on a Thursday evening but on the following Sunday, we started having intermittent call drop-outs on both inbound and outbound calls and a 'ticking' every ten seconds or so on the external parties phone.
Our PBX tech guys have suggested that this is a carrier-side issue but they've been unable to find any issues and it seems strange that the ISDN service had been running perfectly for the 12 months leading up to the upgrade. A restart of the card (LOAD 6 1 2) does not seem to resolve the issue but a restart of the controller (LOAD 1) does seem to rectify the issue for a couple of days but both times I've restarted the controller, the issue has returned.
I'd be interested in any opinions/suggestions you may have.
