.conf includes while using Asterisk Realtime

Hello,

I have a customer that is using iSymphony with Thirdlane and has his dialplan implemented with Asterisk Realtime. iSymphony requires additional contexts to be added from the isymphony.conf file. The file is normally included in the dial plan via the following line in extensions.conf:

#include /opt/isymphony/server/isymphony.conf

This line is in place in the dial plan and "dialplan reload" has been issued to Asterisk but asterisk does not report that the contexts exist.

Is there another method that needs to be used when doing this type of include in a Realtime environment?
