Thank you, but that tells me how to configure the servers for redudancy but my issue is to have two voice gateways in a failover configuration, we are using HSRP but not sure how to set the failover router to become the active gateway, providing DHCP if the primary fails. Any help greatly appreciated.

Hi,

If you're using CUCM you will need to put your 2 Voice Gateways into a Route Group and Route List so that if one gateway fails calls will be routed via the other.

On your Voice Gateways themselves you will need to configure VoIP dial-peers to point inbound calls to your CUCM:

dial-peer voice 22 voip

preference 1

destination-pattern 22.. (Phone Extn)

progress_ind setup enable 3

no modem passthrough

voice-class codec 1

voice-class h323 1

session target ipv4:x.x.x.x (CUCM Subscriber Address)

dtmf-relay h245-alphanumeric

fax rate 7200 bytes 48

fax nsf 000000

fax protocol pass-through g711ulaw

no vad

!

dial-peer voice 23 voip

preference 3

destination-pattern 22..

progress_ind setup enable 3

no modem passthrough

voice-class codec 1

voice-class h323 1

session target ipv4:x.x.x.x (CUCM Publisher address)

dtmf-relay h245-alphanumeric

fax rate 7200 bytes 48

fax nsf 000000

fax protocol pass-through g711ulaw

no vad
