CS Context Overview 221
• 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.
