I have a couple questions as it relates to monitoring a Kamailio SIP Server.
1. Do you have an OID that we can poll via SNMP-GETs to show call completion statistics? Either the % of completion or the accepting/connecting statistics. If you do not have an OID, do you have a syslog or trap message that can be generated?
2. Do you have an OID that we can poll to get a list errors that were generated? Ex-OID for a 408 or 503. If not, is there a syslog or trap?
3. Can you recommend a way to view the MOS score - possible hardware tap on network to get MOS?
Thanks in advance

the snmpstats module exports the statistics of the dialog module, which counts completed calls, failed calls, a.s.o.
You can get the statistics also via MI or RPC control interface, for example with kamctl:
kamctl fifo get_statistics all
2.Do you have an OID that we can poll to get a list errors that were generated? Ex-OID for a 408 or 503. If not, is there a syslog or trap?
There are internal statistics for classes of reply codes and also to some very common ones -- you can get them in the same way, via mi/rpc or snmpstats.
3.Can you recommend a way to view the MOS score -- possible hardware tap on network to get MOS?
Never worked with such thing, maybe someone else can help.
Cheers, Daniel

As Kamailio doesn't handle media by default, we can not get a MOS.
There are multiple ways, most commercial software duplicate a port in a switch and process a copy of all the RTP data (provided there's a central point where you can get this).

Hi,
there is also probing hardware from e.g. tektronix communications - it generates dedicated test calls with defined media streams and then measure the distortion and report MOS values and others.
Best regards,
Henning
