Call Bumping (only INSYS Pocket ISDN Internet)
An ML PPP connection uses both B channels of the S0 bus. In order to answer an
incoming call (i.e. a voice connection) during an ML PPP session, a B channel must
be released. This is called call bumping.
In order to allow call bumping, proceed as follows:
Enable the call waiting function in the S0 bus. It must be enabled in ISDN
and is a service feature of your ISDN connection.
Open the "Properties" of your dial-up connection, which you use for ML
PPP. Enter the command
AT**CMLP=1
as additional parameter.
In case of a call during an ML PPP connection, the INSYS Pocket ISDN Internet
releases a B channel and an ISDN phone connected to the S0 bus can answer the
call.
