[asterisk-users] A problem with IAX2
B.H. Hello! We have several Asterik boxes that are connected to PSTN using PRI cards and they are interconnected using IAX2 trunks so that incoming calls are delivered from PSTN to the servers they belong to. In past we were using asterisk 1.4 on the server that is receiving IAX connections and everything worked as expected. Recently, we have switched to a newer box with asterisk 1.8.22 and then we began to experience sometimes a strange problem: At some point of time, incoming IAX connections begin to get refused by the server and we get the following messages in the logs: WARNING[] chan_iax2.c: Too much delay in IAX2 calltoken timestamp from address X.X.X.X where X.X.X.X is the IP of the PSTN-IAX gateways and all the incoming calls start to be rejected. Direct PSTN calls (both incoming and outgoing) to the same server work OK. The only solution that helps is to kill the asterisk and restart it. All the servers are connected to the same LAN segment, with gigabit switch, there is no problems with the network. No packet loss. There's already bug report present with very similar issue, but it is suspended and, like stated there, the problem is very hard to reproduce.

I too have it there and this does not help :-( Maybe, it's possible to disable calltokens at the originating end? requirecalltoken=no only tells the receiver to accept calls without a valid calltoken. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] Park problem on IAX2 channel
Hi all, I have 2 asterisk box connected with IAX trunk. One box have connected a SIP phone and the second have a TDM card with one analog phone. When from SIP phone I try to park the call from analog phone with #700 the call is correctly parked but in the second asterisk I see this log: -- Executing Dial(Zap/2-1, IAX2/CTM1/STI1|30|rjtT) -- Called CTM1/STI1 -- Call accepted by 172.16.4.1 (format alaw) -- Format for call is alaw -- IAX2/CTM1-2 answered Zap/2-1 -- Started music on hold, class 'default', on IAX2/CTM1-2 -- Zap/2-1 Playing 'pbx-transfer' (language 'en') -- Unable to find extension '77' in context 'from-internal' -- Zap/2-1 Playing 'pbx-invalid' (language 'en') -- Stopped music on hold on IAX2/CTM1-2 The line: -- Unable to find extension '77' in context 'from-internal' appears also with '#', '#7', '', '0'... It seems that the dtmf came across the iax channel and arrive to other asterisk. The are a way to block this dtmf across the IAX trunk?

[Asterisk-Users] Phantom problem authenticating IAX2 with RSA
I'm getting exactly the same behavior as was posted about in
http://lists.digium.com/pipermail/asterisk-users/2004-March/040380.html
I've upgraded (both ends) to CVS stable (CVS-v1-0-06/17/05-13:15:49).
Jun 17 13:46:17 NOTICE[15942]: chan_iax2.c:4053 authenticate: No way to
send secret to peer 'a.b.c.d' (their methods: 4)
Immediately after that, I'll see frames go by with
Tx-Frame Retry[000] Subclass: NEW
Rx-Frame Retry[ No] Subclass: AUTHREQ
Tx-Frame Retry[000] Subclass: AUTHREP
Rx-Frame Retry[ No] Subclass: ACCEPT
that make it look very much like rsa authentication is being done, and the
call is accepted.
I noticed this while cleaning up my IAX config...moving away from
type=friend entries to a type=user and a type=peer entry for each system I
send/receive calls to/from.
i.e. on the remote end, I have:
[my.system.name]
username=my.system.name
type=user
auth=rsa
inkeys=my.system.name
context=my.system.name-iax
qualify=no
disallow=all
allow=g729
allow=gsm
deny=0.0.0.0/0.0.0.0
permit=[IP of my.system.name]
On the end I'm calling from:
[remote.system.name]
type=peer
username=my.system.name
auth=rsa
outkey=my.system.name
qualify=no
disallow=all
allow=g729
allow=gsm
host=remote.system.name
The test call is dialed as IAX2/remote.system.name/${EXTEN}
Is there a problem with my config, or is this just an iax2 cosmetic bug?
Each end does have appropriate rsa keys (readable by asterisk) in
/var/lib/asterisk/keys.
BTW, if I'm reading the docs correctly, there are multiple errors in the
wiki:
http://www.voip-info.org/tiki-index.php?page=Asterisk%20IAX%20authentication#comments
where allow is incorrectly used [in the context of allowing an IP] where
permit was meant.
