I bashing my head against the wall working with the local incumbent telco. I’ve been here before and think I’ve posted about but, here we go again.
- Has been working perfectly for months.
- PRI outage on Friday, service down for 7 hours.
- PRI restored.
- Not getting all calls. Maybe 20% of test calls are getting through.
- Office really needs high uptime so, we swap to the cold spare. Identically programmed so, when we move the PRI cables, lan cable and power, the network sees the cold spare at the same IP address, everything should work nice. Rather than rebooting the device periodically, we will swap to the other device. Because of this history, I know that both devices are programmed correctly and the swapping process works perfectly.
- Even though calls only started dropping after the PRI was down on Friday, the incumbent telco is telling me it’s my equipment that’s the problem. Even though I’ve swapped to the cold spare for about 18 hours and back to the primary unit since then.
- Telco busied out the first B channel on the PRI and calls are routing correctly. I’m really at a loss at this point. They are still telling me it’s my equipment causing the issue.
So, in fairness…
- How can I test this? There is no function on the GXW4504 to simply disable a channel (or is there?).
- How can I prove what the issue actually is? I’ve looked at the various option under Signaling Troubleshooting but, I’m not sure where to start. I’m looking for something, pcap or text file or other, where I can actually look as see what’s going on.
Would anyone here consider themselves an expert on this subject matter and be interested in being hired as a consultant?
