Store Statistical Information of RTP (Release 3)
The SV9100 can now store statistical information of RTP on the SD Card. This information once
stored on the SD Card can then either be retrieved using PC Pro to download or by saving to a USB
stick using telephone programming.
Easy Edit –

Save Statistical Information of RTP - This class of service option sets the
information being saved to SD Card.
Save Store Statistical Information or RTP - This sets the service code that when used RTP statistical
information is saved on SD Card immediately. Normally the RTP statistical information is saved every 1000
telephone calls. Default value is 760.
Service Condition
RTP Information is saved by considering the period as one call as it opens and closes. When closing an
RTP stream and reopening by hold, transfer, etc., it saves as a separate call.
Even if an RTP stream is not able to open, when an RTP Open Request is notified to the VoIP DB, then
RTP statistical information is stored. Since the actual communication is not performed, all information is
set to 0.
The saved information is written in the file on SD Card every 1000 calls. However, the service code
operation can only be performed, when the Save Statistical Information of RTP (PRG20-07-35) is On.
When RTP statistical information is written to the SD Card, it is not concerned with the success or
failure. The number of calls for the writing for every 1000 calls is returned to 0, and begins a count from 1
again.
After saving onto the SD Card, the statistical RTP information in CPU memory is deleted.
When a write error occurs during the writing to the file on SD Card. The RTP statistical information data
being written is canceled including the RTP information in the CPU Memory.
In order to perform the writing to the file on SD Card the task is set as a low priority, so as not to affect
other services.
Saves 20000 calls to a single file, and then saves from the next telephone call to another file.
The number of files to save is to ten files, after that, the oldest file is erased and new information is
saved. Old and new files are decided using the time of the creation date of a file. Therefore, it is
dependent on the clock information on the system at the time of creating a file.
About 4.6MB per file in memory is used. About 46MB memory is used by ten files. (230Byte/call.)
When creating a new file, the system doesn't reserve the memory for 20000 calls, but file size increases
during writing.
When writing the RTP statistical information data , and the capacity of SD card is 30 MB or less, the
oldest RTP statistical information file is deleted until 30MB or more availability is made to SD card.
Even if all the RTP statistical information files are deleted, when sufficient capacity on the SD Card is not
securable at the time of writing, then it becomes a write error and the RTP statistical information data
being written is canceled.
File format is csv.
In the "DATA" folder on SD card, it saves by the name "MMDDhhmms.csv."
When the remote terminal side is not supporting RTCP, only the information on the system side is
obtained and all the information on the remote side is set to 0.
IPLE requires transmission of RTP statistical information every 5 seconds after RTP is opened including
from the remote side and updates to the newest information at the time.
The timing which asks VOIP RTP statistical information is just before closing RTP.
When a call is closed and RTP is closed before receiving the answer of the RTP statistical information
from the remote side. Only the information on the system side is obtained and all the information on the
remote side is set to 0.
The statistical information of RTP on a secondary node of Net Link is also saved by the primary system
