Other Supported Products

Other supported products are listed by request of the Vendor as the same qualified firmware may be supported across several different products. While these have not been specifically tested, the Vendor does fully support this configuration for the listed Qualification Level. Please contact the Vendor for more information on these products.

SIP Trunking Services Qualified for Microsoft Office Communications Server 2007 R2

SIP Trunking enables an enterprise to connect their on-premise voice network implemented by Microsoft Office Communications Server 2007 R2 to the Public Switched Telephony Network (PSTN) directly over SIP.  SIP Trunking services are offerings from IP Telephony Service Provider partners that offer PSTN origination, termination, and emergency services using the SIP protocol. 

Listed below are SIP Trunking Services that have been independently qualified to meet the UCOIP requirements.

Supported IP-PBXs for Microsoft Office Communications Server

The following IP-PBXs are supported by Microsoft but have not gone through the formal OIP qualification process nor was the testing requested by the vendor. Sufficient internal testing has been performed by Microsoft such that specific configurations are supported by Microsoft (where applicable with known limitations). These configurations utilize the commercially available production SIP trunk interface of the IP-PBX vendor but may not be supported by the IP-PBX vendor. In addition, IP-PBX vendor-provided complete documentation for installation and set-up, release notes, or documented support processes may not be available. Wherever possible, Microsoft will endeavor to provide documentation for installation and set-up.

IP-PBX Vendor	Tested Product	Supported Configuration	Software Versions Tested	2007 R2	2007
Avaya	Communications Manager SIP Enablement Services	Direct SIP	4.0
	Known Limitations: Configuration requires setting "Alternate Route Timer(sec)" value from default of 10 sec to 30 sec. The configuration should show "Alternate Route Timer(sec): 30" in the corresponding SIP signaling group. When an call is ringing to the Office Communicator user, the caller (either on an Avaya station or a PSTN line routed through the PBX) will not get ring back tone. This issue has been resolved by Avaya with the 5.x software releases. Quality of Experience reports will not contain information regarding jitter and packet loss. Comfort noise generation is not supported. As a result, comfort noise is not played on Office Communicator. ISDN Failover is not supported from an OCS perspective. If the Avaya PBX is being used for PSTN connectivity and multiple T1's are being utilized, an OC client will not retry a call based on a T1 being unavailable. It may be possible to configure the Avaya to not assign outbound calls from OCS to an unavailable T1, but this configuration was not tested.
Cisco	Cisco Unified Communications Manager	Direct SIP	4.2(3)_SR3a
			4.2(3)_SR4b
			5.1(1b)
			5.1(3e)
			6.1(1b)
			6.1(3a)
	Known Limitations: The PRACK message sent by CUCM 4.2(3) is malformed by missing the MAXFORWARDS header.  As a result, this configuration requires PRACK to be disabled.  By default, PRACK is disabled in CUCM 4.2(3) For Office Communications Server 2007, this support requires update package for Communications Server 2007 Mediation Server: August 2008. OCS 2007 may not appropriately normalize the PAI in the 200 OK or UPDATE, resulting in OC displaying a non RFC3966 formatted global number and in failed RNL on OC. When calling from OC 2007 to a Cisco phone number, after the caller gets connected, the name of the person on the Cisco phone may not be shown on Communicator, and instead OC may display the E.164 number (without a "+") for the person on the Cisco phone. This is resolved in OCS 2007 R2 When calling from OC 2007 to a Cisco phone number, where the Cisco extension is disconnected or out of service, the Cisco IP-PBX may not notify OC 2007 in a timely manner. This has been remediated in OCS 2007 R2.
