As per popular request, I made a patch for bearerbox that enable the following configuration:
# multi-group: group = smsbox-route-between smsbox-id1 = localbox1 smsbox-id2 = remotebox1 # shortcode is optional shortcode = +1234567;+7654321 This is the opposite of "reroute" for smsc's. It routes messages from smsbox/sqlbox/open smppbox to another box that is connected. This allows for: 1. client-to-client routing, concerning open smppbox. 2. Call sms services from one of the boxes. Right now you can only call them via an smsc. 3. Many more interesting things
