SIP peers are SIP-enabled devices or programs that provide telephony communications between Speech Server and callers. Examples of SIP peers are Voice over IP (VoIP) gateways and softphones. For more information about the types of SIP peers used with Speech Server, see SIP Peers.

You use the Speech Server Administrator console or WMI scripts to configure specific settings that enable Speech Server to receive and send calls to the SIP peers.

There are two groups of SIP peers in the Speech Server??Administrator console:

  • Overall SIP peer group ??? This group provides a pool of SIP peers for all the deployment groups in the Speech Server Administrator console. The settings for trusted SIP peers are inherited from the SIP peers in this group.
  • Trusted SIP peer subgroup ??? Each deployment group has a subgroup of trusted SIP peers (that is, those SIP peers that are trusted by the computers running Speech Server in the deployment group). Trusted SIP peers inherit configuration settings from the SIP peers in the overall SIP peer group.

You can configure settings for two types of SIP peers in Speech Server:

  • Default ??? This type provides the basic settings related to communication between the SIP peer and Speech Server, such as name, address, and listening ports. Most SIP peers fall into this category.
  • TIMC ??? This type is reserved for the Telephony Interface Manager Connector (TIMC), a special type of SIP peer that provides an interface between Telephony Interface Manager (TIM)-based telephony boards and the native VoIP communications used by Speech Server. To configure a TIMC SIP peer, the TIMC software must be installed on the computer running TIM. For more information, see How to: Install the TIMC.

To work with SIP peers, you add and configure them in the overall group and then choose which SIP peers should have trusted communications with Speech Server. Only trusted SIP peers can communicate with Speech Server.

Only one type of SIP peer can be trusted in a Speech Server deployment group. Speech Server cannot be configured to communicate with both default and TIMC SIP peers simultaneously.

The following conditions must be true for SIP peers to communicate with Speech Server:

  • The SIP peer must be deployed and configured to handle voice sessions for the phone number addresses mapping to speech applications on the computer running Speech Server.
  • The SIP peer must be configured to send incoming SIP INVITE messages to the Speech Server listening ports. For outbound calling, Speech Server must be configured use the SIP peer listening ports.
  • The SIP peer must be on a network segment that is accessible to the computer running Speech Server. If Windows Firewall is enabled on the computer running Speech Server, it must be configured to allow network traffic between Speech Server and the SIP peer. For more information, see Configuring Windows Firewall for Speech Server.
  • The SIP peer must be configured as a trusted SIP peer for the computer running Speech Server with which it needs to communicate.
