Tracing calls
Tracing calls at SIP / H.323 level
1. Log in to Cisco VCS Control web interface as admin.
2. Go to
Maintenance > Diagnostics > Diagnostics logging
.
3. Ensure all log levels are set to DEBUG and click Start new log.
4. Retry the action for which the problem occurs (such as setting up a call or similar).
5. Click Stop logging followed by Download log.
The log file will contain information related to the events triggered by the action performed in step 4.
My MXP will not create a Multiway call
Whether the MXP uses H.323 signaling or SIP signaling to call the Multiway Conference Factory Alias
is defined by the Multiway URI configured on the MXP.

If the Multiway URI is prefixed with “sip:”, e.g. sip:multiway@domain then the MXP will always make
the call to the Multiway™ Conference Factory Alias using SIP signaling; if it does not have the ‘sip:’
prefix e.g. multiway@domain or has an h323: prefix, e.g. h323:multiway@domain then the MXP will
always make the call to the Multiway Conference Factory Alias using H.323 signaling.

The MXP must therefore be registered to the VCS, or be configured so that it can route calls to the
VCS using the appropriate protocol (H.323 or SIP). Otherwise although “Merge” will be presented on
the screen, when pressed the Multiway call will fail.
