routing from smsbox

not sure if this has come up before, but say if you want to route based on the source number.


I think the best way may be to code a routing group for smsbox, to convert source number to smsc-id,
and then rely on the already routing using smsc-id in bearerbox.

I guess it would be too much recoding to have smsbox capable of connecting to multiple bearerboxes though,
so each smsc-id bind used for this will be in the same bearerbox instance

any thoughts?
