Wrong Number Dialed Using Windows Client

[Martini!]

I have a client who has one user that has an issue when dialing using the 3CX client. When she dials using a 3CX client phone book entry or a BLF button on the BLF panel, will randomly dials 803, which is an all page. It does this randomly on different address book entries. It may happen one or five times a day. I can look at the logs and the phone is being send 803 and the pbx log shows 803 being dialed. This started to happen randomly, and not after an update.

The PBX is 15.5.15502.6 Professional Perpetual. The 3CX client is the latest downloaded from 3CX, 15.5.12227.5. Phone is Yealink T29G with the latest firmware, 46.83.0.55. Phone has been factory reset and re-provisioned. The phone is provisioned with the first two keys being line keys.

Any ideas or thoughts? I am stumped.

Thanks!

Also, I have uninstalled and cleaned orphaned files and registry keys, reinstalled, and reset the welcome email.

Thanks!
