Solved ENGIN VOIP and 3CX V15 - NO Incoming calls

[ALANB]

I am having no end of trouble getting my windows 10 - 3CX box to accept incoming calls. I have changed to V15 and the ENGIN phone number doesn't accept incoming calls any more. (Outgoing calls are working)

port forwards include UDP/TCP 5060 / 5090

When calling from mobile I get TELSTRA message 'We're sorry.. this call cannot be completed ....'

It was working OK with V12.5

Has anyone been able to connect V15 3CX with ENGIN phone numbers.

It appears that ENGIN does not work with 3CX V15. 3CX fails to deliver standard SIP protocols to the provider. This is why ENGIN has been removed from the list of SIP Providers.

You should use a supported VoIP Provider...

OK just an update. ENGIN does work with 3CX V15. There is a less than intuitive concept in creating a connection with a SIP supplier. I have successfully made incoming and outgoing calls using ENGIN. Thanks Nick for your comment, I will be purchasing a copy of 3CX very soon. (My third paid copy). Cheers and I love 3CX again.

Hi Alan, Great to hear that - glad you fixed it and thank you for being our customer

Would it be possible if you could share your resolution on the Forum as we are having difficulty in making outgoing calls on an ENGIN SIP.

Thanking you in anticipation.

Hi SSTech,

Engin works perfectly for me and has for the last month or two been 100% reliable with the 3CX V15.5 connection. I have been using ver12.5 for many years and am very familiar with all manner of pitfalls and problems, all which were resolved successfully. At the moment I am using a full version of 15.5 with engin all whilst living in Germany.

As it was over a month ago since I had these issues, I can't remember how I resolved these problems. Could you outline your issues and I will try to assist.

Cheers
Alan

Hi Alan,

Running 15.5 and all incoming calls are fine. No issues at all. SIP trunk is registered OK.

All internal calls to other phones are working perfectly.

We have 18 extensions are of which are registered and working.

However all outgoing calls are failing.

It appears the issue is the outgoing authentication.

So, not sure if the ENGIN have a setting we need to fix.

Thanks

Peter

Hi SSTech,

OK great. In your sip registration details page. Which Authentication method did you use?

 

[SSTech]

The method is Register /Account based

 

[ALANB]

OK, Next two things to check are

1 your outbound rules (Outbound Rules)
2 FQDN settings (Settings :: Network :: FQDN tab)

Can you tell me your outbound rule settings and also the FQDN setting

 

[SSTech]

Hi Alan,

Would you like to login. Office based system so no issues.

On dedicated server I have no concerns.

Have plenty of backups!!

 

[ALANB]

OK, but please change the Password after I have finished. I have logged in May I make some changes?

No probs Alan. Please make any changes you see fit!

 

[SSTech]

Much appreciated.

 

[ALANB]

OK. I have created a new outbound rule. Your rule may have been problematic. (too many options in one rule - although it does look OK so I left it - It may cause problems with my rule but we can deleting it later.

I have also changed the SIP settings to the new ENGIN preferred settings. This may have been the problem.

Also Do you have a dedicated IP address?

 

[SSTech]

Hi Alan. The IP you logged in with is our Static IP

 

[ALANB]

Are you able to make Outgoing calls now? May I set up an extension to test outgoing calls. With your permission I will test call a local Brisbane 07 number - This may cost money depending on what plan you have with ENGIN

 

[ALANB]

If you can't make outgoing calls then I think we need to look at your port forwards. 15.5 introduced some changes to the port forwards. Where you could use port 80 and 443?? instead of 5000/5001
