Free linphone.org SIP service not working?

Martin Glaser
Hi,

when I try to call my account (from Linphone on iOS), no connection can be established. There is only silence. Yesterday a connection was established, but "busy" signalled.

While registering from Linphone (iOS) works, I have trouble to register from Asterisk:

[Jul 16 21:12:12] ERROR[907] tcptls.c: Unable to connect SIP socket to 37.59.51.72:5061: Connection refused
[Jul 16 21:12:32] NOTICE[902] chan_sip.c:    -- Registration for ... timed out, trying again (Attempt #2)

When I check my logs I see that this problem started already 29th of June and since then it looks like Asterisk was not able to register anymore.

What's wrong?

Best Regards

 Martin

Hi,


Machine 37.59.51.72 has been temporary removed from the sip.linphone.org  cluster.
If you use DNS SRV request against sip.linphone.org it should be transparent to you application.
Best regards

I have a problem with asterisk similar to the OP.

Attempts to register time out, and attempts at peering give the message
"Peer 'linphone' is now UNREACHABLE".

The asterisk 'sip show peers' command shows that asterisk has attempted
to reach 37.59.51.72 (i.e., SIP3).  There is no reference to sip3.linphone.org
at all in my asterisk configuration; only sip.linphone.org is given.

Since you mention SRV records, I checked my resolver, and each of
_sip._udp., _sip._tcp., and _sips._tcp. give sip.linphone.org (5600. 5600, 5601).

Apparently, asterisk's chan_sip driver is not using SRV records in these instances.

To test I added '91.121.209.194 sip3.linphone.org' in my /etc/hosts file, so that
SIP3 would map to the address of SIP.  This workaround allows asterisk to register
and peer.

Since there is no reference to sip3.linphone.org in my asterisk configuration, host
SIP3 must be received from linphone.org during dialog.  How else?

Hello again,

also in my Asterisk configuration is neither a reference to sip3.linphone.org nor to 37.59.51.72.

That here is all:

register => tls://...:...@sip.linphone.org/...

and

[sip.linphone.org]
type=peer
host=sip.linphone.org
remotesecret=...
defaultuser=...
context=public

If I check DNS SRV records, I see:

Correct me if my way to query is wrong (I have no experience with that). Note that I configured my Asterisk to use a TLS connection. I am not sure how to query that. Is it correct to prefix the server name by _sips._tcp.?

What I see above are DNS entries refering to sip3.linphone.org which is 37.59.51.72.

So either Asterisk makes similar queries to the ones above and is directed to 37.59.51.72 or the redirection happens during registration with sip.linphone.org.

Your method to remove 37.59.51.72 from the cluster seems to be wrong to me.

Well, that is interesting.  In my queries, I left out the sip. host,
as in *.linphone.org; your queries include sip. as in *.sip.linphone.org.

Both SRV type queries received answers, and the answers are different.
In queries like _sip._udp.linphone.org, only 1 answer is given, and
it includes sip.linphone.org.

I wonder why these two queries should both receive answers, especially
answers that differ.  A good reason, or error?

I don't know if asterisk[*] is actually doing SRV queries in the form
you used, but if so I would expect it to try sip1 if sip3 is
unreachable.

I suppose I'll keep sip3.linphone.org in my /etc/hosts as a workaround
until linphone folks sort it out.

[*] meaning asterisk chan_sip module.

Re: Free linphone.org SIP service not working?

In reply to this post by Ed Hynan-2
I also think that asterisk is not doing SRV queries, because in that case it would use also the port given there (5223 or 443), wouldn't it? But the error message clearly says that asterisk is trying to reach 37.59.51.72:5061. So that must come from somewhere else. Or maybe there is guesswork going on in the form "if you can't reach what is in DNS then try the default port, maybe that works".

Best Regards
