[cisco-voip] "The Call Cannot Completed as Dialed"

[Paul]

Call me crazy but I'd swear that's a message from the telco.

I am getting this message when: phone A calls phone B and vice
versa (suddenly today after 1 year that it has been working!!)

phone A in the hub location
phone B in a location with 500kbps BW to hub

Phone A can access the web page of B and ping it.
B is normally registered to the same publisher CUCM!!
B is behind a router that does not do NAT or firewalling.

Why is this prompt playing?
I resunched the location BW but i guess that is not the issue.
What debugging could show  me what is wrong?

Thanks and Kind Regards
Anthony
