Pjsip double contacts

Asterisk Asterisk SIP
1

Hello,

Since upgrading to 13.24.1 from 13.23.1, pjsip show contacts shows two entries for each contact. For example:

pbx*CLI> pjsip show contacts

  Contact:  <Aor/ContactUri..............................> <Hash....> <Status> <RTT(ms)..>

However, when examining a single contact, there is only one:

pbx*CLI> pjsip show contact 10_q2yJKX3BI3/sip:10_q2yJKX3BI3@192.168.71.10:5060

  Contact:  <Aor/ContactUri..............................> <Hash....> <Status> <RTT(ms)..>

Interestingly, the only exception is the last entry, to sip.digiumcloud.net, for which there is only one contact. The only difference I can think of is that I’m registering to it:

pbx*CLI> pjsip show registrations

 <Registration/ServerURI..............................>  <Auth..........>  <Status.......>
==========================================================================================

 digium/sip:sip.digiumcloud.net:5060                     digium            Registered

Objects found: 1

I have tried deleting the database entries with database deltree registrar/contact, but when the new entries are added there are still two of each.

None of this seems to affect calls; all seems to working as before. Is this expected behavior?

Regards,
Ian

Update:

I have just updated another Asterisk installation, and it’s showing the same behavior:

cal*CLI> pjsip show contacts

cal*CLI> core show version
Asterisk 13.24.1 built by root @ cal on a x86_64 running Linux on 2019-01-01 19:07:27 UTC

So it’s new in 13.24.1.

Happy New Year!

This is not expected behavior, but is likely just something in the way the data is presented. Please file an issue on the issue tracker[1].

Will do - thanks!

4

We are mysteriously seeing the same exact issue. Was this ever figured out?

5

There is an open issue[1]. It’s only a cosmetic CLI issue, so noone has taken on fixing it as of yet.

THANK YOU sir. I looked thru the issues and could not find it earlier.

Hi guys,

In the CLI I see the same problem on Asterisk version 16.2.1 installed as a debian package on the new Linux Debian 10 Buster. Perhaps it has been fixed on the Asterisk source code but not on the .deb binary package.

CLI> pjsip show contacts

I don’t believe anyone as of yet has touched the bug or fixed it.

9

Thanks for the quick answer. I don’t know about the most recent source code of Asterisk version 16.x.y but you’re right that the Asterisk 16.2.1 package on Debian 10 hasn’t touched it yet.

10

The linked issue is still open. When it is resolved it will be automatically closed and tagged with the fixed versions.

11

Hi guys,

Are there any news? A few days ago there was an update of the Asterisk 16.2.1 binary package on Debian 10 Buster but I see that the problem is still there. This update has not affected this annoying cosmetic problem. I assume the problem has not been solved even on the source version.

Thanks in advance

12

The problem is fixed in the latest release candidates across branches. It will therefore be fixed in the 16.6.0 release. The full version list is on the previously linked issue under “Target Release Version/s”.

13

Typically Debian, and other Linux distributions fix on a version quite early and then back port security fixes to it. That means that, if you want the latest non-security bug fixes, you should build from source and not use the official packges.

14

Hi,
Thanks for the clarification, I am aware that since it is not a security bug it will not be solved quickly by the Debian team, and perhaps never. However, I reported the bug to the maintainer of the Debian Asterisk package.
I compile and install Asterisk from source as of version 1.4 when I used ISDN PRI and BRI cards but now I only use VoIP providers and virtual machines and the features of the official Debian package are enough.

Regards
