I have the chance to play with a couple of E400P cards, each installed in a IBM e330 XSeries servers (2 x 1GHz P-III CPU 2 Gb RAM, 36Gb SCSI HDD with RH8.0 2.4.18-smp kernel), and I'm trying to test/benchmark this e330/E400P combo generating calls thru /var/spool/asterisk/outgoing
One e400P if doing the carrier work making calls and the other just receives the calls:
Server#1 Server#2 caller callee +-------+ +-------+ | Span1 |--E1 crossover cable-->| Span1 | | Span2 |--E1 crossover cable-->| Span2 | | Span3 |--E1 crossover cable-->| Span3 | | Span4 |--E1 crossover cable-->| Span4 | +-------+ +-------+
The basic configuration seems ok, since zttool shows the links are OK.
I'm using this UTP cat5 cross-cable (not shielded): pin1 <--> pin4 pin2 <--> pin5 pin3 <--> pin6 pin4 <--> pin1 pin5 <--> pin2 pin6 <--> pin3 pin5 <--> pin8 pin8 <--> pin7
I'm not really sure this is correct, since I've found only how to connect pins 1,2,4 and 5. The other pins are connected as I supposed it should be.
This is my zapata.conf:
Server#1 zapata.conf (Server#2 has the same zapata.conf but pri_net is pri_cpe)
-------------------------------------- [channels] context=inicio switchtype=euroisdn signalling=pri_net rxwink=300 ; Atlas seems to use long (250ms) winks usecallerid=yes hidecallerid=no callwaiting=yes callwaitingcallerid=yes threewaycalling=no transfer=no cancallforward=no callreturn=no echocancel=yes echocancelwhenbridged=yes rxgain=0.0 txgain=0.0
group=1 signalling=pri_net channel => 1-15 channel => 17-31 channel => 32-46 channel => 48-62 channel => 63-77 channel => 79-93 channel => 94-108 channel => 110-124 --------------------------------------
To generate calls, I've done a small C proggie that generates files in /var/spool/asterisk/outgoing/ like this one (filename and callerid are different for each call):
-------------------------------------- Channel: Zap/g1 Context: default Extension: s Priority: 1 Callerid: 55512345 --------------------------------------
The Dialplans are simple...caller machine just plays a 3 minutes gsm and loops, and the callee machine dilaplan launches an AGI that plays some gsm, records 20 secs of the call and hangups the call.
Server#1 (caller) extensions.conf
-------------------------------------- [general] static=yes writeprotect=no [inicio] exten => s,1,PlayBack(laxana) exten => s,2,Goto(s,1) exten => t,1,hangup exten => i,1,hangup exten => o,1,hangup exten => h,1,hangup --------------------------------------
Server#2 (callee) extensions.conf -------------------------------------- [general] static=yes writeprotect=no [inicio] exten => s,1,Answer exten => s,2,Agi,600agi exten => s,3,hangup exten => t,1,hangup exten => i,1,hangup exten => o,1,hangup exten => h,1,hangup --------------------------------------
Everything works pretty well with just 1 call, but my goal is to generate a much high number (a queue of +50.000 calls), but I've run into some problems...
If I try to generate 120 simultaneous calls (top of lines available with my 4 E1), I get a lot of errors in the logs.
I've tried to sleep(1) the begining of each call, and now I can only generate a maximum of 60~80 simultaneous calls. Could it be due to a cross-over cable problem or maybe the server can't deal with it?
Btw, asterisk gets 100% of all available CPU (user CPU) for 10~20 seconds and then it keeps about 80% CPU usage....
Thas's just a portion of the asterisk log:
