What will be the outcome of an incomingVoIPcall arriving at TK2 from TK1, given the following router configurations?
TK1 Configuration
dial-peer voice 1 pots destination-pattern 1111 port 1/0/0
TK2 Configuration
dial-peer voice 1 pots destination-pattern 2222 port 1/0/0 !
dial-peer voice 2 voip destination-pattern 1111 session-target ipv4:172.16.1.1

A.
The call setup will proceed by matching dial-peer 1 pots, but will have one-way audio.

B.
The call setup will fail.

C.
The call setup will proceed and audio path will be established by matching the inbound call to the default dial peer.

D.
The call setup will proceed, but will have no audio path.

Explanation:
Based on the configuration shown the correct answer concern aVoIPcall arriving at TK2 from TK1 should be “The call will fail”. The reason is that TK1 does not have a dial-peer statement defining a session target with the “session target ipv4:” command. The telephone on TK1 has no route defined on how to reach TK2. Reference page 4-24 ofCVoiceversion 4.1 class books. If the call was originating from TK2 to TK1 the correct answer would be “C” OR if the configurations were reversed then the answer would be “C”.
