With Microsoft Business Voice including call bundle, you will receive a telephone number to make and receive calls. The bundle will give you an allowance of free calls to UK fixed and mobile numbers. However, you will not be part of the Cloud Phone system, which means you will not get an extension number, you will not be included in reporting or recording or any hunt groups.
Purchasing your Teams SIP channel through Cloud Phone means you get the features of an enterprise telephone system and the ability to pool your SIP channels amongst Teams users. Our quote is based on providing 1 line for every 4 Teams users, but our Cloud Phone expert can validate the channel ratio during your consultation.
