We have a client with multiple sites. 3300. One centralized site feeding the others. Only 1 site is affected. And the issue is only since they moved their office several blocks. All of the equipment remained the same. Only 4 users in this office. What happens is basically every incoming call after answering the line still rings about 2 times, then latches. But that's not all. If you press the phone book as an example it doesn't populate in the display, only after about a 2 second delay. Same if you press the voicemail speed call, or any other key. Basically a delay accross the board. Systems are in Chi., users are on Long Island, NY. Once again, only after they moved to another office. Thanks and let me know if more info needed. Hopefully someone ran into a similar issue.
Just to add what was done so far........Mitel and the carrier had us do seperate wireshark captures. And a steady ping to the controller in Chi. never waivered, even while trouble was occuring. Thank you all.
