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.

Hi Alan,

Please test with your Brisbane no. NO issues. Have checked all port forwarding and the 3CX tests come up ok. But that doesn't necessarily means its ok!! IF you need some changes to our NATTING please advise and will do.

Also just as a side note: perhaps you should change your 000 reception to 999 or something else. 000 can be set up as your emergency number

I noticed that the Cisco phone 401 has been setup as a 3cx client. Although I have made this work with the 504g before. I think it best if it was provisioned as a 504g. I am familiar with this model but not he polycoms and linksys models. so You may want to provision them correctly as well.

Which extension are you on. May I call you to check your port forwards

Extension 102
And yes good idea about 000
