Hi Anton.
In version 1.4.4.-a1 i found some issues:
-subusers can not send messages;
-can not alocate sender ID and outgoing routes to subusers;
Janos.
I tested this, I can do all that, except thw route, it is designed only for users
Check log when subuser send message
Also, how do you allocate sender ID? You can rrquest, but admin need to approve, both sub and users must get admin’s approval for sender id
