CircleLoop supports SIP desk phones, and other devices, such as conference/speaker phones and Analogue Telephone Adapters (ATAs), that support SIP. However, not all features are fully supported.
CircleLoop is an app-first solution and the recommended setup for best performance and the richest feature set is to use the CircleLoop Windows or Mac Desktop App, with a wired headset and ethernet network connection.
CircleLoop can however also work with SIP desk phones, and other devices, such as conference/speaker phones and Analogue Telephone Adapters (ATAs), that support SIP.
It should however be noted that the features available when using SIP devices are limited to the following:
|
Hold |
Place the caller on hold, with optional hold music. The configuration of the hold music is managed via the CircleLoop app, but all supported SIP handsets can hold and unhold calls. |
|
Mute |
Mutes your audio, whilst keeping the caller connected. Supported on all SIP Phones |
|
Volume |
Controls volume of the handset/headset. Supported on all SIP handsets where available. |
|
Voicemail |
CircleLoop voicemails are accessible via the CircleLoop apps with voicemail messages transcribed and delivered via email. CircleLoop offers unlimited cloud storage of voicemail recordings and has no concept of mailbox with limited slots. As such, any SIP handset that has a voicemail button to dial in to a mailbox will not function. |
|
Presence |
User Presence is visible in CircleLoop apps, when performing a call transfer. This presence reflects all CircleLoop users, where they are deskphone users or app users. Any SIP handsets with built in presence functionality will not reflect the presence of CircleLoop users. |
|
Transfer |
It is not possible to transfer a call directly from a SIP handset. However, a call that has been answered on a SIP handset can still be transferred via any of the CircleLoop apps. In this scenario the app remotely controls the call in progress allowing you to transfer the call to any team or user in your CircleLoop account. |
|
Call Forwarding |
This functionality is configurable via the CircleLoop apps only |
|
Contacts |
Contacts can be added into SIP device address books manually, and are callable as you would expect. It should be noted that any SIP device contacts will not be synced to a user’s CircleLoop address book. |
|
Caller ID Management |
It is possible to change the caller ID presented to the recipient when making outbound calls using a desktop app. This is configured via the CircleLoop app by selecting a default number. This default number can be any of the numbers assigned to your CircleLoop user, team or menu. |
|
Withhold Number |
It is possible to withhold your number when dialling from a deskphone, simply prefix the dialled number with 141. Please contact the CircleLoop support team to enable this function. |
|
Emergency Calling |
It is possible to call UK Emergency services via a deskphone. Please contact the CircleLoop support team to enable this function. |
