SIP server overview

Last Updated : Nov 30, 2021 |

Avaya Contact Center – Extended Capacity is a SIP server that can connect to external SIP servers, such as Session Border Controller, or other communication systems. SIP servers handle call traffic in the contact center network. The system administrator must specify external SIP servers on the Configuration Server web portal for connecting to the contact center.

A SIP server can do the following:

  • Set up a connection between multiple endpoints.

  • Transmit media parameters and specifications for the communication session for each endpoint using the SDP protocol.

  • Modify media parameters and specifications during a session. For example, a SIP server can update the related media parameters when the agent puts a call on hold.

  • Update endpoint parameters. For example, a SIP server can update the related media parameters when the agent transfers a call to another agent or endpoint.

  • Terminate a session.

For more information about SIP server configuration, see the SIP server configuration section in Administering Avaya Contact Center – Extended Capacity.
