SIPp

Installed from apt package 'sip-tester' onto Bellman.

Hit the server with one request and repeat every 1000 milliseconds. Use 192.168.1.2 as the source IP address (bellman) and send from port 5123.

sipp -sn uac -r 1 -rp 1000 cds.wildsong.biz:5060 -p 5123 -i 192.168.1.2

On the asterisk console,

core set debug 10
sip set debug on

Then I can see

Sending to 192.168.1.2:5123 (no NAT)

So I add a peer called 'sipp' in sip.conf:

[sipp]
type=friend
context=testing
host=192.168.1.2
user=sipp
canreinvite=no
disallow=all
allow=ulaw

Progress: now I get this:

So I add the context and the extension to 'extensions.conf' and do 'dialplan reload'.

[testing]
exten => service,1,Verbose(1,SIP test)
 same => n,Answer()
 same => n,Playback(SIP_Test_Success)
 same => n,Hangup()

And it works! I turn off SIP debug and I can see this in the asterisk console.

sip set debug off
