Hi all,
Does anybody know if it is possible and how to measuring call signalizing speed?
I really appreciate any help.

Define speed. One measurement would just be network round-trip delay the signaling packets experience. Another could be the call setup time. Another still could be how quickly the call agent responds to a signaling event. What specifically are you asking?
The first you can measure with a ping. The later two you would need to review the timestamp on logs to see.

Hi Jonathan,
The idea is try to compare the signaling round trip delay between the ip phone and the cucm on two different sites.

Perform ping from Sita A to site B.

Chris,
Ping is not a valid test. It will not get into the qos.

Sure it is, sims perform it when there is no congestion, QoS comes into play when there is congestion on the network.
No need to get scientific here.

Agree, but maybe there is congestion, And the idea it's to have some instrument (a procedure) to measure sometimes in the day and compare the collected data.
Thank you,

You can use IP SLAs to accomplish most of what you want here. Specifically the VoIP Call Setup Monitoring and UDP Jitter for VoIP Operations. Be warned, these consume real bandwidth. If you are running an RTP test you will need to decrament one call's worth of bandwidth from CUCM CAC to ensure the priority queue is not overrun.
