Microsoft Teams SIP Gateway to support analog phones via Analog Telephone Adaptor (ATA) and Algo overhead paging devices

Announced at Microsoft Ignite, and coming in early 2023, Microsoft Teams SIP Gateway will support analog phones. Allowing you to connect existing analog phones and specialist analog endpoints like door access systems or elevator phones.

Which Analog Telephone Adaptors (ATAs) are supported with Microsoft Teams?

Analog will be supported by connecting a compatible analog telephone adaptor (ATA). There will be models from AudioCodes, Cisco, and Poly:

  • AudioCodes (MP-112 FXS, MP-114 FXS, MP-114 FXS_FXO, MP-118 FXS, MP-118 FXS_FXO, MP-124 FXS)
  • Cisco (ATA 191, ATA 192)
  • Poly (OBI 300, OBI 302)





Many people in the Microsoft UC world will be familiar with the AudioCodes MediaPack gateways.

No word regarding licencing, though I would expect it to work like other devices on Microsoft Teams SIP gateway, e.g. you will need a user or common area phone licence per device, but no additional license for SIP.

Also, no word on Fax or Modem support, which can be a lot more tricky so it would not shock me if that is not supported.

Microsoft Teams SIP Gateway Overhead Paging

Also announced and coming in 2023, SIP Gateway will support overhead paging devices allowing direct SIP Gateway connectivity for pagers, ringers, and speakers. Right now only Algo has been announced as a supported device partner.
