Chapter 1 Configuring Inspection for Voice and Video Protocols
H.323 Inspection
hostname(config-h225-map-hsi-grp)# hsi ip_address
Where ip_address is the host to add. A maximum of five hosts per hsi group are allowed.
To add an endpoint to the hsi group, enter the following command in hsi group configuration
mode:
hostname(config-h225-map-hsi-grp)# endpoint ip_address if_name
Where ip_address is the endpoint to add and if_name is the interface through which the endpoint
is connected to the security appliance. A maximum of ten endpoints per hsi group are allowed.
g.
To check RTP packets flowing on the pinholes for protocol conformance, enter the following
command:
hostname(config-pmap-p)# rtp-conformance [enforce-payloadtype]
Where the enforce-payloadtype keyword enforces the payload type to be audio or video based on
the signaling exchange.
h.
To enable state checking validation, enter the following command:
hostname(config-pmap-p)# state-checking {h225 | ras}
The following example shows how to configure phone number filtering:
hostname(config)# regex caller 1 “5551234567”
hostname(config)# regex caller 2 “5552345678”
hostname(config)# regex caller 3 “5553456789”
hostname(config)# class-map type inspect h323 match-all h323_traffic
hostname(config-pmap-c)# match called-party regex caller1
hostname(config-pmap-c)# match calling-party regex caller2
hostname(config)# policy-map type inspect h323 h323_map
hostname(config-pmap)# parameters
hostname(config-pmap-p)# class h323_traffic
hostname(config-pmap-c)# drop
Configuring H.323 and H.225 Timeout Values
To configure the idle time after which an H.225 signalling connection is closed, use the timeout h225
command. The default for H.225 timeout is one hour.
To configure the idle time after which an H.323 control connection is closed, use the timeout h323
command. The default is five minutes.
