Hi,

I have to monitor a customer who's complaining about bad call quality.

I've installed the prognosis server in our office and the customer's ipoffice is located in their office.

I've set up the rtcp monitoring port to our public ip and i've natted the 5005 port to the prognosis server.

Any idea if the phones use other port to the prognosis server ?

The invenrtory is ok in the prognosis server.

One other question, did the phone receive the RTCP server adresse trough dhcp or when they register ?

What about remote phones ?

You can try playing with the 46xxsettings.txt file and see if that works, it mentions RTCP in there I believe :)

 
Actually, I believe R10 can do that...

For IP Office Release 10.0 and higher, in addition to having the individual phones send RTCP call quality reports the system can also send RTCP reports for calls.
 
Shows how much interest I have in R10 :)
Either way remote monitoring jitter and packet loss won't really help you find the problem, just confirm it's happening, onsite testing is the ticket here :)

 
Then what's that feature in LAN/Voip?

RTCP Collector IP address for phones Default = Blank.
This setting defines an alternate destination for the RTCP Monitor data described in the Enable RTCP Monitor On Port 5005 field above. This enables you to send the data collected to a third party QoS monitoring application.

The Enable RTCP Monitor On Port 5005 must be turned Off to enable this field.

Changes to this setting requires a reboot of the phones.

Quality issues on VoIP are Always* a data network issue.

what are the Bandwith & Qos settings on their internet connection
are internal calls affected as well.
What codec is the customer using
do the data switches support QOS
do they have a seperate Vlans for voice & data
have the prioritys for the Voice & data Vlans been set accordingly.








* at least nobody has had any other cause yet.


Do things on the cheap & it will cost you dear
 
what are the Bandwith & Qos settings on their internet connection => VDSL i think
