Re: 3CX phone application cannot fully connect

@tolu82 

The answer is yes and no. Yes in that a tech from Singapore was able to make it work after 2 or 3 tries. It then worked well (btw there was no good explanation given as to what was wrong). Recently I received a notification that I should update F-Secure which I did. The update promptly broke the system again. So in the end the answer is no.

 

I have been too busy to deal with tech support again to get it fixed. It's kind of annoying turning the security features off, reconnecting, and then turning them back on again..

 

@Jake How do you add that exception in the F-Secure Antivirus product?

 

Regards.

Re: 3CX phone application cannot fully connect

I must add that I'm using F-Secure Protection  Service for Business, for workstations.

 

 

@Jake But no the suggested solution did not work for me.

Got a message from F-Secure support.

 

Stopping the service FSGKHS and renaming the following:

 

<F-Secure>\NIF\bin\

 

fsni32.sys

fsni64.sys

fsnitdi32.sys

fsnitdi64.sys

fsnixp32.sys

fsnixp64.sys

 

to filename.sys.old

 

Starting the service FSGKHS.

 

This worked for me!

Re: 3CX phone application cannot fully connect

@tolu82  You must have a significantly different version than I do. I do not have the FSGKHS service.

 

So what I did was turn off all of the F-secure services and rename the fsni64.sys and reboot.

Will post back if it works.

I'm using F-Secure PSB Workstation Security as I mentioned in an earlier post.

 

Got a new message from F-Secure where they said that the renaming of files was just a step to pinpoint the problem.

 

 

When it worked after doing this procedure they told me that the problem is caused by the Network Interface Framework module.

 

Still waiting for the next step.

Re: 3CX phone application cannot fully connect

Ok, here are my results. I renamed that file "fsni64.sys" and rebooted my computer. 3cx now works just like it should.

 

Now I am concerned that F-Secure is operating correctly. Maybe one of the techs could fill us in.

That testing confirms, that the problem is caused by Network Interceptor Framework.

Have you excluded all 3CX server ports from Web Traffic Scanning?

See pg. 14 of Manual 3CX Phone System for Windows Version 12

Re: 3CX phone application cannot fully connect

@Jake That would make sense, however I cannot find the interface/ui to exempt ports from scanning in my version. I can only exempt programs...of which 3cx is listed as a trusted program.

Re: 3CX phone application cannot fully connect

Hi codeslinger,

 

since there hasn't been any activity on this thread for a few weeks, I just wanted to check in and see if you still have any issues to be addressed?

 

Thanks!

Re: 3CX phone application cannot fully connect

Hello,

Addressed, no not really. I am running f-secure with the network filter (??) disabled. I have the above mentioned file renamed and now it works. Kind of seems like it defeats the purpose of an anti-virus software. My subscription runs out in a few days and at that time I am planning on trying a different company to see if things work better. The 3cx application is really the only compaint I have about F-Secure.
