Working with Spirit Telecom on a mobile twinning issue. Issue is that it won't work. Thier engineers are telling me that Information element 74 was missing from IP Office and that was the cause. Anyone heard of this? thanks
what's crazy is that it worked with Spirit on a different circuit and now with the same carrier it is an issue with the IP Office. I will have to get more information from the customer how it doesn't work. I have kept a distance saying it worked before.
I had something similar happen not to long ago but it was with Time Warner and caller ID. Site was up for years and outbound caller ID no issue.. The customer switched to a new PRI same carrier but,the switch carries terminated new PRI was IP based instead of the 5ess switch old one was terminated to. Since IPO by default sends out unknown number instead of National. I had to change the ICR for all the DIDs to force out National instead of unknown
