When selecting trunks to be used for outbound calls, there are a few problems: 1) The database field for storing the trunk string is limited to 16 charactars. If using an H323 or other custom trunk, this may be too short. 2) The application adds to the end of the trunk string the number to be dialed, this can be a problem for custom trunk (we use H323 for outbound calls). We will put together a patch for the call origination code which will support standard freepbx style replacements for building the dial string. I hope to have it posted this week.
