A call establishment method and corresponding communications terminal for
a trunked radio network such as TETRA (708, 709) to establish a call from
one network (700) to another network (711, 712, 730, 741) through a
gateway (701, 713, 733, 740). A target telephone number is dialled at the
calling communications terminal storing unique associations between
telephone numbers and call types. Alternatively the call type is
requested from a user of the calling communications terminal in case no
call type is stored with the target telephone number. The gateway (701,
713, 733, 740) through which the target telephone number can be reached
is then selected on the basis of the call type.
