Many standard SIP phones to be compatible with Microsoft Teams from early 2021

SIP Phones

Microsoft has announced that from 2021 most SIP phones will be compatible with Teams. Core calling features will be supported for SIP phones from most major manufacturers, including Cisco, Yealink and Polycom. Previously, only Microsoft-certified SIP phones with enhanced firmware were compatible with Teams.

Most handsets produced by mainstream vendors over the last 10 years are SIP compatible. SIP is a protocol used by unified communications platforms to enhance voice telephony with advanced features like video, instant messaging and user presence.

For many businesses, the cost of replacing existing desk phones and room phones with Microsoft-certified devices has previously been a major barrier for moving telephony to Teams. Depending on the brand and features, Microsoft-certified SIP phones typically cost between $200 and $1,000. Consequently, providing new devices to an entire workforce can be expensive, and this is often the largest part of the overall cost of a migration. By eliminating this cost for some customers, Microsoft will potentially accelerate growth in the use of Teams for telephony in 2021.

One limitation is that Teams will only support core calling features on standard SIP phones. Microsoft has not specified which functionality will be supported, but users are unlikely to have access to all the features available on Microsoft-certified devices. Many older SIP phones also lack encryption, which may result in unsecure connections over the internet. 

Microsoft also announced that Skype for Business 3PIP (3rd Party IP) phones will be supported by Teams beyond the previous 2023 deadline. This may encourage businesses to migrate from Skype for Business to Teams telephony. Microsoft has not yet specified whether these 3PIP phones will be treated as generic SIP devices rather than fully-supported endpoints, which would mean that many of the enhanced features of these devices could become unavailable.
