Avaya SBC Release 8.1.1 and later supports integration with Microsoft® Teams (Teams). You can use any deployment type (hardware, VMware, virtualized, Microsoft® Azure, or Amazon Web Services) as long as it supports Avaya SBC Release 8.1.1 and later.
Avaya SBC must include Avaya Aura® Release 8.x or later as part of the deployment with Teams.
Avaya SBC supports the following interoperability features:
  • SIP signaling for UDP on PSTN.
  • The Teams SIP signaling is set up to use TLS port 5061. For security reasons, the TLS version must be TLS 1.2.
  • SRTP interworking with RTP/RTCP on the PSTN side, and SRTP/SRTCP with lifetime for the following cryptography suites:
    • AES_CM_128_HMAC_SHA1_80
    • AES_CM_128_HMAC_SHA1_32
    • AES_CM_256_HMAC_SHA1_80
    • AES_CM_256_HMAC_SHA1_32
  • Refer interworking by handling REFER.
  • Hold/Resume interworking since Teams has its way of handling hold, unhold, and music on hold (MOH).
  • Handling of FQDN and DNS.
  • Number plan manipulation.
  • Teams-specific header injection to assist Teams on failover.
  • RTCP generation in a scenario when legacy SIP PSTN trunks do not send RTCP.
  • Transcoding support for G711u, G711a, G722, G729, and OPUS codecs. The SILK codec is not supported.
