Dial Tone Issue

[troy]

When i start to dial a number i have dial tone then half way though dialing the number dial tone comes back so i end up dialing the wrong number. This seems to be on digital phones only. I have s8730s and G650's with communication manager 5.2.1. I am looking for some help as what to look at to trouble shoot this? Thanks for any response

You need to submit a ticket with Client Services.

Try to do a list trace and see what is happening in the call..Thanks
