TeslaVoice Features

All of the following features are included at no extra cost

SIP Extensions

Each SIP extension on your account is assigned a unique extension number which can be dialled internally, as well as being used to make and receive calls.

Phone Numbers

We provide both geographic (01/02) and non geographic telephone numbers in all UK area codes for making & receiving calls (5 numbers included).


Assign voicemail to each phone line with a personalised greeting, allowing callers to leave messages. Protect them with an optional PIN for remote access.

Time Rules

Direct calls to the appropriate phone line or call group according to the time of day or even the day of the week using intelligent time-based routing.

Call Queues

Place incoming calls into a queue, which can then be easily answered by queue members according to configured rules ensuring that no calls are missed.

Call Groups

Ring a selection of phone lines at the same time or distribute calls between a number of phone lines ensuring the right calls go to the right people.

Pickup Groups

Answer calls to another phone line that is ringing, provided you are a part of that group saving you from moving between desks to answer incoming calls.


Hold telephone conferences of up to 10 participants calling from any location in the world. Protect your conference room with an optional PIN number.

IVR Menus

Direct incoming calls to the appropriate department or employee using a voice-prompted menu. For example press 1 for sales or 2 for support.

Fax to E-mail

Faxes sent to a dedicated number are forwarded instantly to a pre-defined e-mail address ensuring confidentiality of messages and ease of archive.

File Manager

Upload your own on hold music and menu prompt audio files (in MP3 format) to suit your own needs using the secure online file management system.

Itemised Call Logs

Access your call logs 24/7 via the online interface and download them in CSV format for data analysis and auditing purposes when required.

Call Recording

Record calls for quick and reliable fact verification. Recorded calls are charged at an additional 2p per minute and are stored by TeslaOne for 3 months.
