Careful and methodical review of media gateway configurations.
Example from the field:
You have configured Office Communicator Server (OCS) 2007 R2 for inbound and outbound calling to/from the PSTN -- i.e., created location profile(s), enabled some users for enterprise voice, etc. A request is made to the local telecom group to provision a QSIG trunk with a block of DIDs and connect that cable to the media gateway. The gateway status lights show green, which indicates that the connection between the PBX and the media gateway is active, (i.e., "up"). The telecom team informs you that they will "pass" the last four digits of the destination number (DID) to the media gateway. You setup a gateway number manipulation rule to convert the four digits to E.164, (e.g., if the area code and prefix are "208866," your rule is: "+208866+D" -- add a plus sign, the area code and prefix to the four digits). You follow the media gateway setup guide and configure the gateway for QSIG.
