Resolving SIP Communication Problems
Step 6 Deploy the updated dial plan by issuing the chg-dpl:custgrpid=” group_number ” MML command:
Wher:
group_number—Customer group identification number that is associated with the affected dial plan.
Step 7 Re-run the diagnostic trace on the dial plan according to way described in Step 1. If the system finds no
errors, the procedure is complete. Otherwise, return to Step 3 and continue to modify your dial plan.
Note If you repeatedly modified your dial plan and routing data and errors are still appearing in the
diagnostic trace, proceed to Step 8.
Step 8 Contact the Cisco TAC to analyze the problem further and to determine a solution. For more information
about contacting the Cisco TAC, see the “Obtaining Documentation and Submitting a Service Request”
section on page xviii.
Resolving SIP Communication Problems
The Cisco PGW 2200 Softswitch software enables SIP communications. The procedures that resolve
signaling channel and bearer channel problems also serve to resolve SIP communication problems. This
section presents procedures for resolving SIP problems.
Stopping SIP-to-SIP Calls
Cisco PGW 2200 Softswitch software can control SIP-to-SIP calls. To stop a particular SIP-to-SIP call,
log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
kill-call: sip_sig_srv :cid=” name ”,confirm command:
Where:
• sip_sig_srv—MML name for the SIP signaling service that is associated with the SIP-to-SIP call.
• name—SIP call identification name. You can get this name by issuing the rtrv-sip MML command
according to instructions in the “Retrieving SIP Call Information” section on page 3-62.
For example, the
kill-call:sip_svc1:cid=”ccdd33ee-423fdedd-55438954-1@172.22.119.215”,confirm MML
command stops a SIP-to-SIP call that runs on a SIP signaling service that is called sip_svc1:
