Communications Server 2007 R2 SIP Trunking Documentation Roundup
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Office Communications Server 2007 R2 enables an enterprise to connect its voice network directly to an Internet telephony service provider (ITSP) offering public switched telephone network (PSTN) origination and termination over the Internet. This voice configuration eliminates the need for an IP-PSTN gateway to provide PSTN connectivity. This configuration is referred to as SIP trunking. This article is a one-stop shop of links to information about SIP trunking with Office Communications Server 2007 R2.

Office Communications Server 2007 R2 simplifies and reduces the cost of deploying Enterprise Voice by enabling an enterprise to connect its voice network directly to an Internet telephony service provider (ITSP) offering public switched telephone network (PSTN) origination and termination over the Internet. This voice configuration is attractive because it simplifies the deployment by eliminating the need for an IP-PSTN gateway to provide PSTN connectivity. This type of configuration is referred to as SIP trunking.
The Office Communications Server 2007 R2 SIP trunking capability enables the following scenarios:
An enterprise user inside or outside the corporate firewall can make a local or long-distance call specified as an E.164-compliant number that is terminated on the PSTN by the corresponding service provider.
Any PSTN subscriber can contact an enterprise user by dialing a Direct Inward Dialing (DID) number associated with that enterprise user.
This article provides links to the information published so far regarding SIP trunking with Office Communications Server 2007 R2.
