Features List

  • 2 Lines

    2 Lines

    Easily adapt your telephony service according to the size of your business.

    2 Lines

    Multiple Lines provide you with a cost effective business solution, allowing you to adapt your telephony service depending on size and nature of inbound calls.

    How does it help my business?

    One of the most important features of a communications system is flexibility. Multiple lines mean it is possible to have one line going into your business but have several different telephone numbers, allowing traffic to be directed to a specific number. This is particularly useful for separate business features or marketing campaigns as you can direct or monitor calls accordingly.

    One main advantage is that you can add more lines or give each extension an individual phone number according to the size of your business, adding or removing lines as required. When in use, you are alerted to incoming phonecalls on each different line and can place one customer on hold whilst dialling out from a different line or answer an alternative incoming call.

  • Speakerphone


    Perfect if you're after an impromptu conference or can't pick up the handset.


    Enjoy hands-free conversations at the touch of a button using the speakerphone feature. With a microphone and loudspeaker, the phone allows several people to speak within one conversation, while the loudspeaker projects the voice of the recipient. A user can switch from receiver to speakerphone any time during an active call using the corresponding button on their keypad or screen.

    Types of speakerphone

    Speakerphones use two different systems - full-duplex or half-duplex. The phones Usomo provide are full-duplex, meaning everyone is able to speak and be heard at the same time.

  • Call Transfer

    Call Transfer

    Transfer calls easily with a dedicated call transfer button.

    Call Transfer

    Need to transfer a call to a colleague?

    Relocate your customer calls through to a different number or extension. During an active call simply press the transfer key, dial the desired number and press send.

  • Conference Calling

    Conference Calling

    Hold an impromptu conversation with two or more other parties.

    Conference Calling

    Conference calls are an essential and cost effective method of communicating with your colleagues or customers.

    How does it help my business?

    Coordinate your meetings, arrange instant conferences or hold quick consultations between colleagues in either the same office or in geographically different locations. Conference calls save time and minimize the use of resources whilst increasing productivity.
