I have an irritating issue with 7925G phones registered to CUCM 188.8.131.52000-1
When you dial for an outside line we have a route pattern set for 9.@ to use the PSTN gateway
So users dial 901234567890 and it dials fine. Although after it starts dialing you do see the 9 dropped on the display.
If you then redial by pressing the green phone button on the 7925G which brings up the last dialled calls list (with no 9 in the number) if you press it again to dial. It calls our operator which is on 0.
This issue does not happen on 6921, 7942, 7945, 7975 i have connected to the same CM. They retain the 9 in the dialled number list.
