Remove Plus From Request URI OCS 2007 R2 : bypass RFC 3966 compliance for OCS R2

October 25, 2009 By: Yann Espanet Category: Interoperability, Office Communication Server, SIP trunk

How to make OCS 2007 R2 non-RFC 3966-compliant ?
Office Communications Server 2007 Mediation Server uses a plus sign (+) to prefix E.164 numbers in the Request Uniform Resource Identifier (URI) for outgoing calls. Unfortunately, some IP-PBXs don’t comply with RFC 3966 and do not accept numbers that are prefixed with a plus sign (+).

In OCS 2007 R2 use a new WMI setting, RemovePlusFromRequestURI, which is described in this TechNet article called Enterprise Voice Server-Side Components.
According to the TechNet article, Office Communications Server 2007 R2 introduces two new Windows Management Instrumentation (WMI) settings for Mediation Server. The first new setting specifies how Mediation Server processes E.164 numbers in outbound calls. The second new setting enables Quality of Service (QoS) marking on Mediation Server.

Handling E.164 Numbers in Outbound Calls (OCS 2007 R2)
By default, E.164 numbers in the Request Uniform Resource Identifier (URI) for outgoing calls are prefixed with a plus sign (+). Most Private Branch eXchanges (PBXs) process such numbers without problem. Certain PBXs, however, do not accept numbers that are prefixed with a plus sign.

To ensure interoperability with these PBXs, Mediation Server has a new WMI Boolean setting called RemovePlusFromRequestURI, which has two values: TRUE and FALSE. If your PBX does not accept numbers prefixed with a plus sign, the value for the WMI setting should be set to TRUE, which causes Mediation Server to strip the plus sign from a Request URI for outbound calls. The default is FALSE, which causes Mediation Server to pass the outgoing INVITE’s Request URI, To URI, and From URI unchanged.

The TechNet article also discusses compatibility with PBXs that do not support the plus (+) sign.

By default, E.164 numbers in the Request URI of outgoing calls from Office Communications Server 2007 R2 are prefixed with a plus sign. Most PBXs process such numbers without problem. Some PBXs, however, do not accept numbers that are prefixed with a plus sign and do not route those calls correctly.

Additionally, the From headers of inbound calls from some PBXs does not conform to RFC 3966 because they are not prefixed with a plus sign. Microsoft Office Communicator cannot resolve these numbers to the correct user.

To assure interoperability with these PBXs, Office Communications Server 2007 R2 has a new Mediation Server setting for WMI called RemovePlusFromRequestURI. This setting can be set to YES or NO. The default value is NO.

- If a PBX downstream from the Office Communications Server 2007 R2 Mediation server does not accept numbers prefixed with a plus sign, set the value of RemovePlusFromRequestURI to YES. This causes Mediation Server to remove the plus signs from the Request URIs of outgoing calls. It also causes the plus signs to be removed from the To and From URIs.
- If the downstream PBX accepts numbers prefixed with plus signs, leave the value of RemovePlusFromRequestURI set to its default value of NO. This causes Office Communications Server 2007 Mediation Server to pass Request URIs, To URIs, and From URIs unchanged (that is, with plus signs).

Choose between insecure or “not working” : To apply or not MS Crypto API security update KB974571 on OCS …

October 19, 2009 By: Yann Espanet Category: KB articles, Office Communication Server

You have to choose between beeing secure or stop working with OCS according to Microsoft !:

Your evaluation period may be expired with this error in event viewver :

Event source: OCS Server
Event id: 12290
Event text: The evaluation period for Microsoft Office Communications Server 2007 R2 has expired. Please upgrade from the evaluation version to the full released version of the product.

So, you follow the “Upgrading Office Communications Server 2007 Evaluation to the Full Released Version” document :

http://www.microsoft.com/downloads/details.aspx?FamilyId=54A5521D-A928-46F2-8BF7-125DA636DD2E&displaylang=en

BUT here’s the result :

OCS Setup log :

Failure
[0xC3EC78D8] Failed to read the Office Communications Server version information. This can happen if the computer clock is not set to correct date and time.

 

After some research I’ve found that the workaround was to remove  the MS Crypto API security update KB974571. So I removed the update, rebooted the machine, and OCS 2007 R2 was up and running again, without any issues.

What is the position of MS regarding this issue :

http://support.microsoft.com/kb/974571/en-us

Microsoft recommends to postpone installing KB974571 on any LCS 2005 / OCS 2007 /OCS 2007 R2 servers.

“Microsoft is investigating this issue, and will determine the most appropriate way to address it. Customers who are not running OCS or LCS server are not affected by this known issue, and can safely ignore this issue.

Customers who have deployed the OCS or LCS product on a server should assess the risk that is involved to decide whether to install the security update on that server. These customers should revisit this Knowledge Base article often, because this article will be updated as soon as more information and a resolution are available.”

Nice one from MS !
