Interoperability

Last Updated : Sep 08, 2022 |

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.
