VoiceEncapPeer33
tag = 1, destination-pattern = '5558810',preference = 0,
Admin state is up, Operation state is up
type = pots, prefix = '',
session-target = '', voice-port = 1/1
VoiceOverATMPeer333
tag = 2, destination-pattern = '559...',preference = 0,
Admin state is up, Operation state is up
type = voatm, session-target = 'ATM0'
nsap '47.0091810000000002F26D4901.567856785678.56',
Router2# show dial-peer voice
VoiceEncapPeer44
tag = 20, destination-pattern = '5559810',preference = 0,
Admin state is up, Operation state is up
type = pots, prefix = '',
session-target = '', voice-port = 1/1
VoiceOverATMPeer444
tag = 10, destination-pattern = '5558...',preference = 0,
Admin state is up, Operation state is up
type = voatm, session-target = 'ATM0'
