Hello Everyone,

I just have a little problem with our phones, and was hoping someone could this problem to bed.

Phone A Rings: Staff A picks up phone, transfers to Phone B. No Problem

Phone B Rings: Staff B picks up phone, attempts to transfer to Phone A, Goes straight to voicemail, does not even ring on Phone A.

Basically my boss can pick up calls and transfer them to me. I however cannot Xfer them back to him, when i try it i just hear his voicemail.

Please if anyone can help its driving me nuts, as i cant xfer he has to keep coming to my desk.

Thanks for your time.
