Real call rate in Netork

[soohyung choi]

run C90,MXP

We connect vidoe conference using vc call rate option 1920kbps

but monitor 2.5M flow in PRTG program (over recive,transfer rate)

Call rate in VC and  flow rate in Network is different?

if these is different, how fix Call rate comparing  network line speed ?

[Nick Halbert-Lillyman]

Is 1920 Kbps your max call rate or your default call rate?

Make sure you set it as your max.

1920 is default call rate, but i change call rate often

At that time, monitoring call rate in PRTG is over flow always

[Nick Halbert-Lillyman · Accepted solution]

Yes but you should be able to change the maximum call rate instead of the defayult call rate, at least on the C90 (not sure about the MXP).

Does it happen when the other end places the call? It could be the recieving endpoint setting the call rate, you should ensure that the setting is checked at both ends.

Lastly, are you calling via VCS? Check the default call rate on VCS.

thank for your answer

vcs is no one

i understand your knowledge..

but my curiosity is that Call rate in status of Codec and Badwidth Flow using PRTG is different

for example,

Using 2M mpls line, what is moderate call setup and reason for that

Not too sure if I understand the question correctly, but....you also need to allow for overheads, which is roughly 20%, so for a 1920 call rate you will need close to 2.5Mbps of bandwidth.

This might be of interest (requires a free account to read);
