Step 1 |
show sccp Before the start of a call, use the show sccp command to verify that the MTP or transcoder device is successfully registered with Cisco Unified Communications Manager:
Example:
Router# show sccp
SCCP Admin State: UP
Gateway IP Address: 192.168.20.1, Port Number: 0
IP Precedence: 5
User Masked Codec list: None
Call Manager: 192.168.20.11, Port Number: 2000
Priority: N/A, Version: 5.0.1, Identifier: 3
Call Manager: 192.168.20.12, Port Number: 2000
Priority: N/A, Version: 5.0.1, Identifier: 1
Call Manager: 192.168.20.13, Port Number: 2000
Priority: N/A, Version: 5.0.1, Identifier: 2
.....
Software MTP Oper State: ACTIVE - Cause Code: NONE
Active Call Manager: 192.168.20.12, Port Number: 2000
TCP Link Status: CONNECTED, Profile Identifier: 10
Reported Max Streams: 1004, Reported Max OOS Streams: 0
Supported Codec: pass-thru, Maximum Packetization Period: N/A
Supported Codec: g711ulaw, Maximum Packetization Period: 30
Supported Codec: rfc2833 dtmf, Maximum Packetization Period: 30
RSVP : ENABLED

Step 2 |
show sccp connections During the call, use the show sccp connectionscommand to display information about the active SCCP connections established for the call, the DSP farm service type (MTP or transcoding), codec (for example, pass-through or g711ulaw), and remote end information:
Example:
Router# show sccp connections
sess_id conn_id stype mode codec ripaddr rport sport
17537646 19438263 mtp sendrecv pass_th 192.168.20.5 35548 16576
17537646 19438260 mtp sendrecv pass_th 192.168.22.1 16832 19164
Total number of active session(s) 1, and connection(s) 2
|
Step 3 |
show sccp connections details Use the show sccp connections details command to display details about active SCCP connections, including the internal call leg ID:
Example:
Router# show sccp connections details
bridge-info(bid, cid) - Normal bridge information(Bridge id, Calleg id)
mmbridge-info(bid, cid) - Mixed mode bridge information(Bridge id, Calleg id)
sess_id conn_id call-id codec pkt-period type bridge-info(bid, cid) mmbridge-info(bid, cid)
17537646 - 326 N/A N/A swmtpmsp All RTPSPI Callegs N/A
17537646 19438263 324 pass_th 20 rtpspi (221,326) N/A
17537646 - 326 N/A N/A swmtpmsp All RTPSPI Callegs N/A
17537646 19438260 325 pass_th 20 rtpspi (222,326) N/A
Total number of active session(s) 1, connection(s) 2, and callegs 4

Step 6 |
show sccp statistics Use the show sccp statisticscommand to display the SCCP messages exchanged between the RSVP agent and Cisco Unified Communications Manager:
Example:
Router# show sccp statistics
