CS Interface Configuration
Example: Configure Digit Collection
In the following example the SmartNode sends the bloc of numbers either when the asterisk
character '*' is received or after 4 seconds have elapsed since the last dialed digit.
SN(if-h323)[h323_0]#
digit-collection timeout 4
SN(if-h323)[h323_0]#
digit-collection terminating-char *
21.6 Configure Direct Call Signaling on VoIP Interfaces
Call signaling is a basic requirement needed to set up and close down a call between two endpoints.
A call can be established between two VoIP interfaces, that is either between two IsoIP or between
two H.323 interfaces. So that a call can be set up the VoIP interface needs the IP address of its remote
device. In direct call signaling this is configured for each VoIP interface directly. In an H.323 network
it is possible to obtain the remote IP addresses automatically by a gatekeeper. This is called
'gatekeeper routed call signaling'. To configure an H.323 interface for 'gatekeeper routed call
signaling' refer to Chapter 25, “Gateway Configuration”.
Note:
If you specify direct call signaling for an H.323 connection make sure that the registration
authentication service (RAS) is disabled. For more information on RAS refer to Chapter 25, “Gateway
Configuration”. For an example refer to the examples at the end of this chapter.
Note:
Compared to H.323, the ISoIP signaling is simpler, faster and more efficient.
