Documentation for syslog messages

Hi there,


I'm trying to debug an issue regarding phone call qualities on a multicell m700 setup.


I tried to dig into syslog message but I didn't find any documentation about syslog messages. Some are straightforward but others are a bit more cryptic like those two.
- [ HS: 5, Pmid:00106, CallId#11704, RxCnt:1065, Discrd:32.7 %, Type:Relay]
- [ HS: 4, Pmid:00205, CallId#8605, rJit: 13852.625, rRTT: 0.000, rR:0.00, rMOS:1.000000, rLoss:57996.4 %]


Thanks in advance,


Gaëtan

Gaetan,


The log entries indicate what appears to be two calls. 


1. The first one appear to indicate the handset 5, was on a call (CallId#11704) and 32.7% of the received packets (RxCnt:1065) were discarded.


- [ HS: 5, Pmid:00106, CallId#11704, RxCnt:1065, Discrd:32.7 %, Type:Relay]


Without more information on this call (was the handset the caller or callee, what was the problem with the call, firmware version on base and handset) it is a little difficult to offer more information. If you want to deep dive into "discards" I believe the ETSI EN 300 175-5 standard addresses this 




2. The second call (CallId#8605) on handset 4 would indicate a call quality issue based on the R-factors and rMOS of 1


- [ HS: 4, Pmid:00205, CallId#8605, rJit: 13852.625, rRTT: 0.000, rR:0.00, rMOS:1.000000, rLoss:57996.4 %]


I believe the standard that defines call/speech quality is the ITU-T PESQ p.862 standard.


Some things that could be causing this are DECT rssi signal strength from the handset to the base, Network issues, firmware on the base and handset (see firmware release notes for known issues). You may want to take a look at our Wiki article which discusses doing a DECT Multicell deployment and usage of the Site Survey tool on the handsets in order to do an assessment and use for troubleshooting call issues.

Thanks a lot for those information. With fields explained I would be able to diagnose better.
