While handling a call, it may be necessary to pass the phone call along to a user, call queue, or an external phone number. This can be done through transferring.
There are three different types of transfer that can be utilized depending on how exactly the call needs to be transferred and handled:
- Blind Transfer - Transfer a call directly to another person without talking to that second person. This is sometimes referred to as a “cold”, “unassisted”, or "unattended" transfer.
- Assisted Transfer - Speak with the person being transferred to before completely transferring the call. This is sometimes referred to as a “warm” or “attended” transfer.
- Voicemail Transfer - Transfer a caller directly to a general mailbox or the voicemailbox of another user.
Use the module below to review how you can use these types of transfers on your StratusHUB mobile app:
Blind Transfer
A blind or a cold transfer allows you to transfer a call to another destination without establishing a conversation with this new call recipient. The first call is put on hold until the call is transferred successfully.
1. On an active call, tap the Transfer 
button.
2. When prompted to select the type of transfer to use, tap Blind Transfer.
3. On the Keypad, type the other person's extension or telephone number.
Use the Other Pages of the App to Transfer a Call
You can use the other tabs of the app to start a call with the person receiving the transfer.
If you have a contact for the other person, you can go to the Contacts 
tab, select a contact to transfer the call to, and tap the Call 
icon next to their contact number.
If you have talked with the person to transfer the call to in the past, go to the Call History 
tab, select a call log from that person, and tap Call option to transfer to that person. 
If you intend to transfer the caller to someone that has left a voicemail message, go to the Voicemail
tab, tap a voicemail left by the person to transfer the call to, and tap the Call 
button.
To transfer the caller to a person you have messaged before, go to the Chat 
tab, tap the conversation with the person you would like to call, tap the Options 
icon, and select 
Call. 
4. Tap the Call button on the Keypad to send the transfer on its way.
Assisted Transfer
An assisted transfer, also known as a warm transfer, allows you to call the destination you want to transfer to, which can be a great way to check and make sure that destination is ready for a transfer.
To make an assisted transfer:
1. On an active call, tap the Transfer button.
2. When prompted to select the type of transfer to use, tap Assisted Transfer. 
2. On the Keypad type the other party's extension or telephone number and press the Call button.
Use the Other Pages of the App to Start a Separate Call
You can use the other tabs of the app to start a call with the person receiving the transfer.
If you have a contact for the other person, you can go to the Contacts tab, select a contact to transfer the call to, and tap the Call icon next to their contact number.
If you have talked with the person to transfer the call to in the past, go to the Call History tab, select a call log from that person, and tap Call option to transfer to that person.
If you intend to transfer the caller to someone that has left a voicemail message, go to the Voicemail tab, tap a voicemail left by the person to transfer the call to, and tap the Call button.
To transfer the caller to a person you have messaged before, go to the Chat tab, tap the conversation with the person you would like to call, tap the Options icon, and select Call.
3. Speak with the second caller once they answer.
4. When both callers are ready, tap the Complete Transfer button to complete the transfer.
Quick Tip: If you need to cancel the transfer, tap the Cancel Transfer button to end the second call. Resume the first call to give the first caller their options.
Voicemail Transfer
One of the dialable codes that can be used on the Stratus mobile app is 03. When 03 is dialed in front of an extension number, you can be directly taken to that extension number's voicemailbox.
For example… If a user needs to leave a voicemail for extension 100, they can dial 0-3-1-0-0 from their app to be taken directly to x100's mailbox. They can wait for the greeting to stop playing to leave a message.
If a user needs to check extension 100's mailbox for them, they can dial 0-3-1-0-0. Once they hear the mailbox's greeting, they can press star (*) to interrupt the greeting and enter x100's voicemail PIN when prompted.
The 03 code can be used to transfer an active call to a user's voicemailbox as well. To transfer a caller to a voicemailbox using the 03 code…
1. On an active call, tap the Transfer button.
2. When prompted to select the type of transfer to use, tap Blind Transfer.
3. On the keypad, dial 03 and the user's extension number.
Quick Tip: You can add a Contact for a mailbox. This contact would be set to have 03 and an extension number as the contact number for the contact.
For the example above, the contact is set to dial 03 and the extension number 500 so that calling or transferring a call to this contact sends the caller to the general mailbox directly.
3. Tap the Call button on the Keypad to send the transfer on its way.
