Possible Firewall isssue, is the WebRTC service set to Reject or Local? If you can’t get it working, open a support ticket.

#9

The firewall is not activated. A support ticket is allready opened.

Thanks!

#10

I’ve tried to remove and reinstall sangomacrm and zulu module, but it eorks in the same way. User’s zulu configuration are reset to deffault, but softphone still does not work. It’s very annoying because it workes for a week, but now, we have 100 extensions with this issue, and custommer is getting angry :frowning:

Regards

#11

Today I started to have identical issue on one ZULU UC client - and tried almost everything without luck. On remote location ZULU softphone is offline and cannot reconnect. Originate call works without issue.

#12

Yes! We have lots of issues with zulu uc too. It still seems to be very buggy :frowning:

Maybe someone can help us…

Regards

#13

Does anyone know if asterisk version is important on this issue? I use asterisk 11.

Regards

#14

Upgrade to 13, 11 is end of life:
https://wiki.freepbx.org/display/PPS/Changing+Major+Asterisk+Versions+on+the+Fly

#15

Zulu soft phone doesn’t work properly on Asterisk 11. You need 13:

#16

I have Asterisk 13 and have this issue and only on remote ZULU client. Clients on LAN same as PBX server work properly.

#17

Finally SOLVED!!! :grinning: Just upgraded to asterisk13 and it started working again!!!. Thank to anyone!!!

Best regards!

#18

Probably you have port 8089 not properly opened…Did you check it?

Regards

#19

I’ve opened both 8002 and 8089 ports on clients side and server side.

#20

Did you try to telnet to the 8089 port?

#21

Finally, I have resolved this issue.

Somehow in my firewall WebRTC service was set to “Reject”.

After setting them to “Internet” and “Local” remote ZULU softphone has connected.

#22

Cool!

#23

DAMN!! After upgrade to Asterisk 13, it seemed to work the first hour, but now, some modules are stoped: restapps, uco, xmpp and zulu.

This what i get in the log:

http count exceded on 1000 sesions.

Any idea?

#24

Browse to Settings, Advanced Settings and increase the http “Session Limit” to a higher threshold.

#25

Ok, can I get any trouble because of this? Is this a serious problem?

Regars

#26

I usually just bump the 1000 up to 10000, I’ve not seen any negative consequences.
