Scenario: In this scenario there are 3 routers interconnected, with 3 VRFs namely Android, IOS and WP7 created. VNET trunk is configured in order to reduce the complexity and administration effort in configuring the routers in between.

Scenario: In this test lab setup, there are 2 CM clusters and 1 CME and they are using SAF to advertise and learn their dial plan. Both CM clusters are sharing the same SAF Forwarder, on the other hand CME are co-host with the SAF Forwarder using the same ISRG2 router.
The IOS version is 15.2, and it is a bit different from the configuration in the past. The “external label” is removed from the EIGRP service family configuration, the new XMCP service routing is introduced. The SAF Forwarder is the XMCP server and the UCM is the XMCP client.

Note
- When privacy on hold is enabled globally, when the phone enabled privacy (the privacy button is on), you can't see the phone is on hold on the shared line. If you disable the privacy on hold, then even the privacy button is on, you can see the phone is on hold.
When you have started to work on CME, you will find that there are several types of shared DNs that is possible which allow great flexibility to fit your customer needs. In this post I will lay out 3 scenarios with configuration and expected result, so that you can get better understanding on how it works.
My environment: CME 7.0
Scenario 1 - one ephone DN for multiple ephone
ephone-dn 1 dual-line
number 4001
ephone 1
button 1:1
ephone 2
button 1:1
- When receive a call to 4001, both ephone 1 and 2 will ring.
- ephone 1 answers call, ephone 2 in remote in use state
- another incoming call will go to ephone 1 second channel
- yet another incoming call - will busy out, the call will not roll over to ephone 2
- ephone 2 can't use that line for outgoing call
Scenario 2 - 2 ephone-dn with same number with preference
ephone-dn 1 dual-line
number 4001
preference 1
ephone-dn 2 dual-line
number 4001
no huntstop
huntstop channel
ephone 1
button 1:1
ephone 2
button 1:2
- ephone-dn 2 is preferred to ring when somebody calls 4001
- no huntstop on ephone-dn means it continues to search for another ephone-dn with the same number, so the call will roll over to ephone 1 when ephone-dn with at least 1 channel occupied, because of the huntstop channel command
Scenario 3 - 2 ephone-dn overlays to the same button
ephone-dn 1 dual-line
number 4001
preference 1
ephone-dn 2 dual-line
number 4001
no huntstop
huntstop channel
ephone 1
button 1o1,2
ephone 2
button 1o1,2
- Both phones will ring. Say for example ephone 1 answers the call, ephone 2 still able to receive new incoming calls to 4001, and make call using the line 4001
- When ephone 1 answers the call, a new call to 4001 coming in and ephone 2 will ring, without showing call waiting on ephone 1
- If you want call waiting, then use "c" instead of "o"
