Connecting Cisco 2801 Voiceports

Here two approach of connecting a Cisco 2801 voice port to Cisco Unified Communication Manager (CUCM).

  1. Configure the voice port directly which make it use H.323 protocol and add them to the CUCM server
  2. Add the routers voice port to be manage directly from CUCM and set the router to download the config from CUCM

Let’s look at the first approach. MGCP-to-H.323

  1. Configuring H.323 on the voice port of the 2801Voice

  2. 2801voice(config)#dial-peer voice 1101 pots
    2801voice(config-dial-peer)#destination-pattern 1101
    2801voice(config-dial-peer)#port 0/0/0
    2801voice(config-dial-peer)#exit
    2801voice(config)#

  3. Configuring H.323 to connect to MGCP (CUCM)

  4. 2801voice(config)#dial-peer voice 1000 voip
    2801voice(config-dial-peer)#destination-pattern 10..
    2801voice(config-dial-peer)#session target ipv4:10.30.100.15

  5. Add the 2801Voice router as H.323 gateway in CUCM

  6. At this stage, the 2801Voice connected phone can call to the CUCM managed IP phones but not vice versa.

  7. We need to add RoutePattern to make all work

  8. Now the calls can be initiated both ways. From CUCM managed IP Phones to the POTS or vice versa.
