What a relief!  This all makes so much sense now.

The calls were failing at the PSTN.  We've recently removed our default DN from our PRI in order to allow CLID to pass through an IP Phone forwarded to a cell phone.  This problem with the 1-8XX has just come up since the default DN was removed.

Thank you guys!

Is it failing at the PSTN or UCM?   If at the PSTN then off the top of my head I know that many 8xx numbers are restricted by area code.  As an example if the 8xx number points to (404)555-1212 some providers do not allow 8xx calls originating from (404) or anything that would be considered a local call.  This is done to avoid the per minute charges associated to the 8xx number when a caller could have dialed a local number.

If it is failing at the PSTN I would try a wide range of 8xx numbers to verify.

Strange problem.  We discovered that if a DN does not have an "external phone number mask" configured, the set will not be able to dial a 1-8XX number.  It can dial any long distance number but not a 1-8XX number.  The route patterns of the 1-8XX numbers are configured with the same options as the long distance route patterns.  What is the relationship between an external phone number mask and call routing?
