First, we use Trixbox CE 2.8.04 stable and are very pleased with it overall.
We added a second office, and thus a second trixbox. We created an IAX2 truck between the two servers, and that went fine. Both servers see each other as peers/friends.
To dial extensions in office 2 from office 1, users dial 8 then the three digit extension number and the connection is made, no problem.
Some of those office 2 phones are in ring groups... for example, extensions 501 through 506 are in ring group 500.
If I dial 500 from any phone within office 2, extensions 501 through 506 ring as expected.
If I dial 8-500 from office 1, we get a message that the number we have dialed is not valid. If we dial 8-501 through 8-506, that extension rings.
We set this up with freepbx exclusively - no editing configuration files.
I'm assuming we simply missed something "obvious", though experimenting on and off for a couple of weeks hasn't been fruitful, and searching here didn't find us much joy either (maybe we didn't use intelligent search words?)
Any advice/suggestions would be appreciated.
