I have connected two ericsson md110 via two cisco router together.
these PBX systems has modem from remote configuration.
after all config the PBX extention from bith side can reach eachother without problem.
but when PBX admin want to establish a remote conection via modem ( he dials from one pbx to another for remote managment) the connection will be established but exactly after 3 or 4 seconds the connection will be lost.
it sees very strange for me any idea please?
Thank you for your advise
