Hello Uli, Thank you very much for your informative response.
I totally agree with you that TCP-probe may be a painful path to deploy and support. I will definitely look into CallManager by SNMP. Since we are new to the world of Cisco, can you point us to the right direction on where we are read me about CallManager, CDR/CMR, CISCO-CCM-MIB and Cisco-SNMP-Server? Thank you in advance and wish you and your team the very best.

Asking the CallManager by SNMP. You have to activate the CDR / CMR recording, then try a snmp-walk We didn't test this way. But we found hints in the net. Actually we tested the CISCO-CCM-MIB for inventory-purpose. Please keep in mind that you have to activate a (Cisco-)SNMP- Server in the web-interface of the callmanager in addition to the running linux-SNMP-Server. 2. Asking the devices directly. You are right - this can be done by a TCP-Probe, only. You have to collect your information from the different (HTTP-)status pages of the phone. We did a lot of tests but finally gave up. There is no way to implement a single TCP-Probe for all devices. The variables are: - language - kind of device - software-version With this variables the HTML-code changes, You will get several - HTTP-Page-Names - Descriptor-names - Delimiters To define regular-expressions fitting for all cases is nearly impossible. You can try to write 4 different TCP-Probes but only if you are sure about - the amount of only 4 different kinds of devices - that nobody will switch the language, - the device will not be updated. The variables for call-quality are ... Jitter (avg/max) ... MOS LQK (avg/min/max) ... Latency From the HTTP-Page you will get the summary of the last completed call. So the Min / Max gives you additional information of the best and worst part of the call If you need more detailed information you have to use a sniffer or Cisco-Service-Monitor-Appliance (sold with the CUOM). If you are interested in our Test-TCP-Probes please feel free to contact us.
