PBX Configuration

Cisco Gateway Basic configuration

In order to activate the IVR on the voice gateway you only need to specify where applying the IVR. This will be done once because the further operations will be automatically managed by IVR Manager itself.

Supposing you have the company PSTN number 870978651 configured as follow:

dial-peer voice 1 pots
incoming called-number 870978651
direct-inward-dial
port 1/0

and you would like to add the main dispatcher running the day and night behavior as previously configured.

You only need to add the following command: service sv_main

The dial peer will become as follow:

dial-peer voice 1 pots
service sv_main
incoming called-number 870978651
direct-inward-dialport 1/0  

Also add in global configuration mode the command:

application
global
service alternate DEFAULT  

Should the dispatcher fail to load, the DEFAULT IVR Behavior will apply, i.e passing through the call without treating.

Cisco Gateway Advanced configuration

Main Concepts

On Cisco voice gateways you can have for voice configuration:

• pots dial-peer
• voip dial-peer

Each of these can handle incoming and outgoing leg. Examples:

	dial-peer voice 1 pots
		description THIS IS A POTS DIAL-PEER HANDLING AN INCOMING LEG USED FOR CALLS FROM PSTN 
		incoming called-number 2978651 
	!
	dial-peer voice 2 pots 
		description THIS IS A POTS DIAL-PEER HANDLING AN OUTGOING LEG USED FOR CALLS TO PSTN 
		destination pattern 0T 
		port 1/0:15 (depending on the physical ISDN PRI/BRI or analog ports installed) 
	!
	dial-peer voice 3 voip 
		description THIS IS A VOIP DIAL-PEER HANDLING AN INCOMING LEG. 
		incoming called-number 7… 
		dtmf-relay h245-alphanumeric 
		codec g711ulaw 
        no vad 
    !
	dial-peer voice 4 voip 
		description THIS IS A VOIP DIAL-PEER HANDLING AN OUTGOING LEG. 
		destination-pattern 8000 
		session target ipv4:<ip_address>
		dtmf-relay h245-alphanumeric 
		codec g711ulaw 
		no vad 

But you can also collapse incoming and outgoing leg on the same dial-peer:

dial-peer voice 5 voip
incoming called-number 7…
destination-pattern 8000
session target ipv4:<ip_address>
dtmf-relay h245-alphanumeric
codec g711ulaw
no vad 

IVR on Voip dial-peer

Until this chapter we have always seen IVR scripts applied on pots dial-peer.

An important feature of IVR based on Cisco gateways is the capability to apply an IVR script to a voip dial-peer more than to a pots one.

Following a sample configuration of such case:

    application
    global
    service alternate DEFAULT 
    !
    voice service voip
        allow-connections h323 to h323
    !
    voice translation-rule 9
        rule 1 /.*/ /646/ 
    ! 
    voice translation-profile ivrmanager 
         translate called 9 
    ! 
    dial-peer voice 1 voip 
        service sv_main 
        translation-profile incoming ivrmanager 
        incoming called-number 8888  // 8888 is a virtual number to catch the call for the IVR script 
        dtmf-relay h245-alphanumeric 
        codec g711ulaw 
        no vad

Please, notice that an IVR behaviour triggered by a voip dial-peer cannot transfer to another IVR Manager dispatcher defined on the same router.

Troubleshooting

if experiencing  audio issue for some audio files, add this commands in the voice gateway configuration

http client cache memory file 10000
http client connection timeout 10
http client connection idle timeout 10
http client response timeout 300
