Converting Skype for Business | SIP Phones to Microsoft SIP Gateway
AudioCodes recommends that customers who have deployed legacy devices, migrate to SIP Gateway via Device Manager.
Microsoft SIP Gateway lets your organization use AudioCodes SIP phones with Microsoft Teams.
Compatible AudioCodes phones are:
|

AudioCodes' Skype for Business IP phones with standard SIP firmware |
The conversion preserves enterprises' investments in legacy phones. The conversion enables SIP phone users to sign-in to Teams with corporate credentials and make and receive calls.
