packaging the ISDN voice frames is not synchronized with the remote ISDN clock, this may
result in bit errors. In case of fax applications not one page could be transmitted.
•
We need two ISDN ports, the first one for the ISDN phone, the second one for the public
ISDN network. This is described in section 'Configure ISDN Ports'.
•
Furthermore we need two PSTN interfaces, each bound to an ISDN port. (This is described
in section 'Configure Call Routing')
•
To use ISoIP we need an ISoIP interface. (This is described in section 'Configure Call
Routing')
•
To support call routing we have to configure Session Router routing tables and the ISoIP and
PSTN interfaces. (This is described in section 'Configure Call Routing'). Calls are routed:
•
from the ISDN phone with number 1xx-5xx, or with prefix 0041 for CH, to main
office with a fallback to PSTN
•
All others are routed from the ISDN phone to PSTN and
•
from PSTN or main office to the ISDN phone
•
We have to specify codec G.711 in the ISoIP gateway. This is described in section 'Configure
an ISoIP VoIP Connection'
•
Furthermore we need in the IP context two Ethernet ports and their corresponding IP
interfaces.
