Title: Incoming IAX rejected "CAUSE : No authority found"
Post by: paul_xedos on December 10, 2007, 11:25:32 PM

Having worked on this one a few days I feel I am getting close to receiving my first incoming IAX call but seemed to have hit this final hurdle which has me stumped. Dialing 08458629999 as a would be incoming IAX call now receives "Sorry number is temporarily unavailable" which is a big step up from the silence I was previously receiving. The asterisk server is natted but 4569 has definitely been forwarded

iax2 show registry shows no entries

iax2 show peers looks good though

Code: [Select]

sme*CLI> iax2 show peers
Name/Username    Host                 Mask             Port          Status   
gradwell-user/gradwell-pass        193.111.200.135 (S)  255.255.255.255  4569          OK (54 ms)but iax debug returns:-

Code: [Select]

Dec  9 17:16:33 NOTICE[4004]: chan_iax2.c:6977 socket_read: Rejected connect attempt from 193.111.200.135, who was trying to reach '448458629999@'I'm not sure if the fact that there is nothing after the @ symbol above is significant. I would have thought the server IP should be there but can't be sure

further iax debug output:-

Code: [Select]

Tx-Frame Retry[000] -- OSeqno: 000 ISeqno: 001 Type: IAX     Subclass: REJECT
   Timestamp: 00004ms  SCall: 00004  DCall: 00001 [193.111.200.135:4569]
   CAUSE           : No authority found
   CAUSE CODE      : 50
My settings are:-
gradwell control panel:-

Code: [Select]

IAX2/gradwell-user:gradwell-pass@80.xx.xxx.xx/448458629999The 80.x.x.x address above relates to the non-natted public address of the asterisk server.  I'm assuming the port forwarding gets it to the real 192.168.x.x private address. A tcpdump -i eth0 port 4569 does show incoming traffic when the call is made  so I'm assuming its getting through ok
   
iax.conf :-

Code: [Select]

[gradwell-user]
type=peer
host=iax.gradwell.net
qualify=3000
canreinvite=no
username=gradwell-user
fromuser=gradwell-user
secret=gradwell-pass
disallow=all
allow=alaw
allow=ulaw
[448458629999]
type=user
context=mainmenu

Code: [Select]

[mainmenu]
      include => extensions

        exten => 448458629999,1,agi(selintra,Inbound,${EXTEN})
I have also tried changing iax.conf a bit to reflect gradwell's advice

Code: [Select]

[gradwell-user]
type=peer
host=iax.gradwell.net
qualify=3000
canreinvite=no
username=gradwell-user
fromuser=gradwell-user
secret=gradwell-pass
disallow=all
allow=alaw
allow=ulaw

[448458629999]
type=user
host=dynamic
username=gradwell-user
secret=gradwell-pass
disallow=all
allow=alaw
allow=ulaw
context=mainmenu
but no different - call still gets rejected instantly

My dialplan for mainmenu looks like this:-

Code: [Select]

sme*CLI> show dialplan mainmenu
[ Context 'mainmenu' created by 'pbx_config' ]
  '448458629999' => 1. agi(selintra|Inbound|${EXTEN})             [pbx_config]
  'fax' =>          1. GoToIf($["$FAX" = ""]?3:2)                 [pbx_config]
                    2. GoTo(extensions|${FAX}|1)                  [pbx_config]
                    3. Playtones(congestion)                      [pbx_config]
  'h' =>            1. Hangup()                                   [pbx_config]
  'i' =>            1. Playtones(congestion)                      [pbx_config]
  's' =>            1. agi(selintra|CheckState|)                  [pbx_config]
  't' =>            1. GotoIf($["${OPEN}" = "YES"]?t|4)           [pbx_config]
                    2. Voicemail(su${SYSOP})                      [pbx_config]
                    3. Hangup()                                   [pbx_config]
                    4. Goto(extensions|${SYSOP}|1)                [pbx_config]
                    5. Hangup()                                   [pbx_config]
  Include =>        'extensions'                                  [pbx_config]

-= 6 extensions (12 priorities) in 1 context. =-
Finally pointing the 448458629999 to something other than the selintra agi to say a sip extension fails in the same way. Sorry for the long winded posting. I'm pretty sure its my config and not selintra but I've run out of things to try so any suggestions gratefully received

Cheers
Paul

Hello Paul,

Let's see if we can help...

This has to do with the way IAX destinations are created and the way in which SAIL creates the receiving set-up.  Most IAX set-ups use the "friend" stanza to set things up in iax.conf.  SAIL uses the twin peer/user entries. 

Let's look at your IAX address at Gradwell (who, by the way, we have nothing but praise for)...

IAX2/gradwell-user:gradwell-pass@80.xx.xxx.xx/448458629999

This will attempt to deliver a DNID (Dialled Number ID) of 448458629999 to a stanza called gradwell-user.

The thing is, you don't have a user or friend stanza called gradwell-user.  You do have peer entry called gradwell-user but that won't help.

So...  you can create a stanza called gradwell-user or you can change the delivery address at gradwell.  Quickest way is to make a small change to iax.conf.

Click on Headers=>iax.conf and add the following at the bottom...

Code: [Select]

[gradwell-user]
type=user
context=mainmenu


issue a commit and make your call again.

I think this may get you back on the road.

Kind Regards

S
