But what is the software limit of the library?
Support >>>
There are 2 issues facing the total number of lines the media engine can support.
1) Architectural limitations imposed by the operating system.
Each process has a max amount of memory it can use. Depending on the stack
size of each process thread, you are limited to the total number of threads you can have in an
application. This is the number one factor in increasing the max number of supported phone
lines in a media engine. I don't have hard numbers for you right now but I think we have
gone as high as 500-800 lines without modifications of the current product.
To go higher requires that we change the default stack size of threads in the application
process and/or possibly turn off selected media engine functions that create new
threads - such call recording, conferencing, etc. In this case we have broken the
1024 line scenario.
2) Speed of the underlying hardware
The max number of lines that can be used on a host machine also depends on the underlying
host hardware. We don not publish execution capabilities for host hardware because of the
huge number of differences that can exist. We are however working on publishing some sort of
normalized operating data somewhere in the future. There are posts in the forum that discuss
these issues.
<<< You
How much is a license for let’s say 512 channels or 1024?
Support >>>
Unknown at this point.
<<< You
I guess a dual XEON could easily handle that if there is no transcoding (like G711-> G729) involved?
Support >>>
Yes. Exactly correct.
These are good questions. Please post all future questions to the support forum so others may benefit from
our interchange. You may remain anonymous.
Thanks,
Support
