[Asterisk-Users] ASTERISK AND 120 CONCURRENT CALLS

[Scott Stingel]

Hi Sebastian-

My guess is that running 4 E1's with transcoding on all channels will
overpower any single processor solution.  I base this only on my own testing
with 4 E1's running a simple IVR solution, with no transcoding.  The
processor (2.8 GHz Xeon) barely keeps up with this load.  I have 5 systems
installed that run this kind of load.  I tried dual xeons and this didn't
improve things much, but I was running an older 2.4 kernel.
 
These results could be a bit pessimistic.  My load tester produces a high
volume of short calls.  There is likely a lot of call setup & teardown load
contributing to the overall load.  
 
Someone should try a multiprocessor solution with 4 E1's and some
transcoding and see where the limit really is.  Should be easy enough if you
have 2 boxes available - running 4 E1's on one to generate calls to 4 E1's
on the other.

E1's, only G729 and from SIP to E1 or from E1 to SIP

Will you have E1s? will you restrict users to 729 or will you allow other
codecs? will most calls be from SIP to SIP? or SIP to E1 lines?

		hello all, does anyone has experiencie using asterisk with a
digium CARD using G729 managing 120 concurrent calls with SIP and/or H323???
I wanna know if Asterisk is stable doing this....because we wanna implement
it in some locations!!
	 
	Thanks All!!
