IP_VIRTBOARD — information about an IPT board device
h323_max_calls
The maximum number of IPT devices that can be used for H.323 calls. Valid values are in the
range from IP_CFG_NO_CALLS (=0) to IP_CFG_MAX_AVAILABLE_CALLS (=2016).
The default value is 120. This field must not be set to IP_CFG_NO_CALLS if sip_max_calls
is also set to that value. When the library is being started in 3PCC operating mode, this field
should be set to IP_CFG_NO_CALLS (=0).
sip_max_calls
The maximum number of IPT devices that can be used for SIP calls. Possible values are in the
range IP_CFG_NO_CALLS (=0) to IP_CFG_MAX_AVAILABLE_CALLS (=2016). The
default value is 120. This field must not be set to IP_CFG_NO_CALLS if h323_max_calls is
also set to that value. When the library is being started in 3PCC operating mode, this field must
be set to a value that is no greater than the number of licensed channels.
localIP
The local IP address of type IP_ADDR. See the reference page for IP_ADDR, on page 540.
h323_signaling_port
The H.323 call signaling port. Possible values are a valid port number or IP_CFG_DEFAULT.
The default H.323 signaling port is 1720.
sip_signaling_port
The SIP call signaling port. Possible values are a valid port number or IP_CFG_DEFAULT.
The default SIP signaling port is 5060.
