I have an issue with one of my offices that has me extremely puzzled.
When users call users in other offices, sometimes the calls get cross-connected, where they are suddenly talking to another caller.
Our telephony provider is insisting it is my network, but I have this office router and switches configured the same as our other 5 offices that don't have this issue.
They are now trying to say it is an MPLS issue from our Telco, but I figure I would be seeing issues with data going over that link as well.
Has anyone ever experience this "crosstalk" before?
The routers at the offices are 2811/2851, with 10meg MPLS WAN between, and 3560/3750 PoE switches for the phones.
Any advice or tips would be greatly appreciated!
