[Serusers] problem with the ser+pstn gateway - sr-users

19 Nov 2004


      hello friends,
i was actuall trying for the ser+gateway
but i was missing some where .
my idea is that any number stat
it gives message as seesion progress with the
message type 183
the same is working in between the two sers
i.e one user agent registered to the one ser server
can be able to place call to another ser server user
agent
iam pasting my ser.cfg here please guide me where
am i going wrong.
