OK. I did that, but now, all I do is get into an infinite loop with the registrations at the callee. Here's the gist: https://gist.github.com/ticklingcontest/a0754549a88dc748f52dIdeally, here's what I need:callee registers, and accepts an infinite number of calls.caller registers, and then sends INVITES an infinite number of times so as to keep the total number of calls per the (-l parameter).It is not clear to me how I would loop at the callee scenario or caller scenario.
You don't loop anything. sipp runs the scenarios itself repeatedly until -m calls have been processed.
I'd start without your script or the csv files and just get a simple 1 call scenario to work.
If you want some good examples, look at the Asterisk testsuite tests/channels/pjsip/basic_calls scenarios.
Here's a caller file I used often...
register
pause 1 sec
invite
pause 1 sec
bye
pause 1 sec
unregister
To simulate a call from a phone with extension/endpoint name 1100, run it like so...
# sipp -sf reg_and_call.xml -s 1100 -au 1100 -ap <password> -m 1 <server:ip>
If you want it to resister/call/unregister 100 times with 10 parallel calls over TCP, run
# sipp -sf reg_and_call.xml -t tn -s 1100 -au 1100 -ap <password> -m 100 -l 10 <server_ip:port>
Once you get that working by itself to an existing extension, set up your callee the same way, then call it from a normal working extension and make sure it responds correctly.
Then have your caller call the callee, first as a single call, then try multiple calls.
Only when you have that working should you introduce your injection files.
What is really confusing in the caller script apart from the real confusion I have with -m and -l parameters, is how the caller's INVITE goes out from the same port as the registered port especially when they are called as two separate processes. Does sipp write a dot file somewhere where it gets its information from?
Nope.
BTW, In this model, I pass the CSV file that is pre-generated for the calls using a python script that looks like this:SEQUENTIALcallerID1;AsteriskIPAddress;[authentication username=silly password=sillier];calleeID1;callDuration1;callerID2;AsteriskIPAddress;[authentication username=silly password=sillier];calleeID2;callDuration2;...callerIDn;AsteriskIPAddress;[authentication username=silly password=sillier];calleeIDn;callDurationn;etc.Again, any help is appreciated. I can see how this is turning into a sipp tutorial, so I understand if you have issues dealing with this here, but I can tell that SIPp help is very sparing online.Thanks!
I'll say again... If you want some good examples, look at the Asterisk testsuite tests/channels/pjsip/basic_calls scenarios. There are both inbound and outbound scenarios, authed and unauthed.

I appreciate your energy into this: https://gist.github.com/ticklingcontest/4762a57457b73db1a170Hmmm.So are you running 1 instance of the script for each call? I think that's the issue.Why not let sipp do the work?For the callee, combine registration.xml and callee.xml into the same file and set -l to the max number of simultaneous calls to process. Then set the transport to tn instead of t1 and just let it sit and listen for connections.Same thing for caller, except for the registration.Now you only have 2 instances of sipp.On Sun, Mar 20, 2016 at 10:15 AM, George Joseph <george.joseph@xxxxxxxxxxxxx> wrote:On Sat, Mar 19, 2016 at 8:29 PM, Tickling Contest <tickling.contest@xxxxxxxxx> wrote:Thanks again, George,I am running PJSIP v. 2.4.5 that is prescribed for Asterisk 13.7.2.

There cannot be network related latencies as the entire test is in the local network.Any insight is deeply appreciated.Those errors you're seeing are outgoing connection attempts so there a few things to check...What version of pjproject are you running? There's an issue in 2.4.5 and earlier where TCP sockets aren't being reused. It's fixed in their trunk. Unfortunately, you can't use their trunk with Asterisk 13.7.2 because of a new api they introduced. You'll have to use Asterisk's current 13 branch from git. If you 're going to do that, check out the bundled pjproject option which also has that patch.Check that sipp isn't terminating early and forcing Asterisk to open a new connection just to send the BYE.How many connections are you attempting?If you really want to get the max connections, set the --enable-epoll option on pjproject's ./configure line (assuming you're on Linux) and set PJ_IOQUEUE_MAX_HANDLES to 5000 or something. This won't fix the connection refused messages however.On Sat, Mar 19, 2016 at 12:09 PM, George Joseph <george.joseph@xxxxxxxxxxxxx> wrote:I'll bet your pjproject install still has the default value of 64 for PJ_IOQUEUE_MAX_HANDLES.
