If you want to transfer all calls, you can do this from the phone itself using the CFALL softkey and then entering the mobile number.
āForward Allā can also be set by the admin from the phone page.
You can also set forward rules on the CUCM for when the line is busy for both internal and external calls. Additionally, you can set the timer for how long it should ring before forwarding if not answered.
If you want to transfer a call, you can do this by pressing the transfer button and dialing the number to which you would like to transfer the call.
From your post, I believe you are looking for an option where calls to your manager also ring on your mobile phone. This can be done using the Mobile Connect option, as mentioned by @Roger Kallberg , and that would be the best solution.
Sounds like a typical shared line to me. This is standard configuration in Communication Manager and isnāt anything special.
The 3905 phone is a single-line phone. Considering this, you can keep both your manager and assistant on the same number as a shared line, as @Roger Kallberg mentioned. This way, both phones will ring.
However, if you want them to have separate numbers and need a phone with a button for the managerās number on your phone, you will need to change the secretaryās phone to one that supports at least two lines. This way, you can assign the managerās number as a second line on the secretaryās phone, allowing her to answer calls coming to the manager.
Another option is using Manager Assistant.
Not from what I can think of. The last bit, ie "In case he is absent, call after two rings should be automatically transfered to assistant's phone." can be done by simply setting up call forward no answer and adopting the time to match two rings.
When a call arrives, he cannot transfer it directly to the secretaryās number without answering by pressing the speed dial button if configured. The available option to divert call without answering is iDivert, and it will divert the call to voicemail.
He can transfer the call another way: When a call arrives, he should answer it and then press the transfer button. If a speed dial is configured for the secretary, he can press that button; if not, he should dial the secretaryās phone number after pressing the transfer button. This will divert the call to the secretaryās phone.
When he is on leave, he can set call forward all from his phone by pressing the CFALL soft key. If a speed dial is configured for the secretary, press that button; if not, press the CFALL soft key and dial the secretaryās number. This way, all calls coming to his phone will be diverted to the secretary. Once he is back from leave, he can press the CFALL soft key again to cancel the call forward all.
