Analog Gateways connected to OCS 2007
Depending on the country where OCS 2007 Enterprise Voice will be deployed, it might become necessary to connect analog Gateways to OCS 2007 Mediation Server. If there is no way to avoid this, a Gateway should be chosen that has been certified for OCS 2007 (http://technet.microsoft.com/en-us/office/bb735838.aspx). Furthermore please note:
· On Inbound calls: Neither calling nor called party information will be submitted to OCS, unless the Gateway has the chance to add this information. Another problem is that you can only assign as many DID extensions to OCS as you have analog lines coming from the PBX/PSTN.
· On Outbound calls: Unless the Gateway has some special functionality implemented, that allows the Gateway to address the correct analog extension line that has been associated to a certain extension based on the calling party number, the Gateway will use any available of the analog extension lines for outbound calls. This leads to the fact that called parties might get signaled wrong calling party numbers. Also since any extension line will be used for outbound calls, it might happen that OC users, that are being called from the PSTN/PBX world via the Gateway, will be signaled as busy to the calling party even though they are not in a call on OC.
