Asterisk IAX2 not listening on port 4569

Asterisk Asterisk Support

Hi folks

I’ve trawled the forum and FAQ and googles till the sun has set and still I have no idea why my Asterisk (1.2.9.1) is not listening on 4569.

During startup it clearly states that it is listening and has bound to port 4569 but when i use nmap or telnet it clearly is not listening on the port and therefore is not accepting any incoming calls.

Anyone seen this before.

Later I’ll upgrade to the latest release but thought I’d throw my stupidity to the wolves first !

Many thanks

John

What does your iax.conf look like? remove obvious passwords and IP addresses.

Hi Ian

I’ve stripped out all the comments and am left with:

[general]
bindport=4569
bindaddr=192.168.1.xx
allow=all
disallow=g723.1
disallow=lpc10
tos=lowdelay

[voiptalk]
type=peer
username=uuuuuuuuu
secret=ssssss
host=iax5.voiptalk.org

[01xxxxxxxxx]
type=friend
username=01xxxxxxxxx
context=voip-in

Any clues?

By the way - outgoing works fine.

Hi Ian

No traffic on tcpdump as the port is not open to listen for any traffic.

Hi Ian

Found it - I think…

I added

           permit=0.0.0.0/0.0.0.0

like in the sample file, and now it works.

I probably need to tighten up that definition for security but at least it is working.

Thanks
