Activating the Voice Port

After you have conﬁgured the voice port, you need to activate the voice port to bring it online. Cisco

Conﬁguring the H.323 Gateway

In this release, basic gateway Registration, Admission, and Status (RAS) protocol capability is

extendedto theCisco MC3810. Other features,such as authentication, authorization,and accounting

(AAA) enhancements for security and accounting services, interactive voice response (IVR),

Integrated Services Digital Network (ISDN) redirect number support, and rotary call pattern

support, will be offered in future Cisco IOS releases.

To conﬁgure the H.323 Gateway, you need to perform the following tasks

• Conﬁguring POTS and VoIP Dial Peers

• Enabling VoIP Gateway Functionality

• Conﬁguring Gateway Interface Parameters

Conﬁguring POTS and VoIP Dial Peers

The ﬁrst step in conﬁguring the H.323 gatewayis to deﬁne the applicable POTSand VoIP dial peers.

The POTS dial peer informs the system which voice port to direct incoming VoIP calls. The VoIP

dial peer deﬁnes how to direct calls that originate from a local voice port into the VoIP cloud to the

session target. The session target command indicates the address of the remote gateway where the

call is terminated. There are several different ways to deﬁne the destination gateway address: by

statically conﬁguring the IP address of the gateway, by deﬁning the DNS of the gateway, or by using

RAS. If you use RAS, that gateway determines the destination target by querying the RAS

gatekeeper. See the “Conﬁguring Dial Peers” section on page 9 to deﬁne dial peers for VoIP.
