Is IAX2 Working?

[dallas]

Hi,

I registered a number yesterday and haven't been able to see an IAX call arrive in my Asterisk server. I switched to SIP and I see the call. Unfortunately I don't allow unauthenticated SIP calls so the call gets a recorded message from my Asterisk.

So is IAX working or do I have something configured incorrectly?

I've fixed the unauthenticated call issue and calls are handled OK. Still no IAX calls.

How did you fix this unauthenticated call issue?

I used the Nerd Vittles solution...
I added the following to extensions_override_freepbx.conf

[from-sip-external]
exten => _.,1,NoOp(Received incoming SIP connection from unknown peer to ${EXTEN})
exten => _.,n,Set(DID=${IF($["${EXTEN:1:2}"=""]?s:${EXTEN})})
exten => _.,n,Goto(s,1)
exten => s,1,GotoIf($["${ALLOW_SIP_ANON}"="yes"]?from-trunk,${DID},1)
exten => ipkall1,1,GotoIf($["${SIPCHANINFO(peerip)}"="66.54.140.46"]?from-trunk,400,1)
exten => ipkall1,1,GotoIf($["${SIPCHANINFO(peerip)}"="66.54.140.47"]?from-trunk,400,1)
exten => ipkall2,1,GotoIf($["${SIPCHANINFO(peerip)}"="66.54.140.46"]?from-trunk,400,1)
exten => ipkall2,1,GotoIf($["${SIPCHANINFO(peerip)}"="66.54.140.47"]?from-trunk,400,1)
exten => s,n,Set(TIMEOUT(absolute)=15)
exten => s,n,Answer
exten => s,n,Wait(2)
exten => s,n,Playback(ss-noservice)
exten => s,n,Playtones(congestion)
exten => s,n,Congestion(5)
exten => h,1,NoOp(Hangup)
exten => i,1,NoOp(Invalid)
exten => t,1,NoOp(Timeout)

This piece of code allows unauthenticated SIP calls only from the IPKall servers that are directed to ipkall1 or ipkall2 on my pbxinaflash.

In FreePBX -> General Settings set 'Allow Anonymous Inbound SIP Calls' to no.

Thanks for your quick response. BTW, do you have the link to Nerd Vittles solution you mentioned above?

Sorry for the delay... It took me some time to find the article again...
It's here... http://nerdvittles.com/index.php?p=208

Also this thread on the forum... Resolved: ipkall setup - PBX in a Flash Forum
Good luck.

I think it's easy only to add two following strings to your ipkall peer(s) in sip.conf
deny = 0.0.0.0/0
allow = 66.54.140.46/31

Evgen,

Yes I'm sure you are correct. I got the code from the Nerd Vittles site and it worked so I left it at that. I also noticed that FreePBX 2.5.1.1 you can do this for extensions on a per extension basis.
