3CX Windows Installation Config Issues

[Gavin Nortje]

Hi

Please could I ask for assistance.

We have a 3CX that we inherited on a customers site and have the following setup.

1. VM with 3CX installed (Windows 7)
2. Yeahlink Handsets
3. Mikrotik Router

All works fine if everything boots together.

If the router is only rebooted the SIP trunk shows registered but I cannot make any inbound calls, i get a dead tone.

BUT if i reboot all services on the 3CX it start working, is there anyway to get around this?

Hello @Gavin Nortje

The first thing you need to do is see what is causing the issue. The next time you restart the router start a wireshark capture on the server and make an inbound call. See if the Invite reaches the PBX. If not look at the Mikrotik configuration and check why the call is not reaching the PBX.
If the call does reach the PBX check why the PBX rejects the call. The Activity log of the PBX can also provide useful information regarding this.

It is never a good idea to share captures in a public forum. I would creating a ticket with our support department so they can take a look at the issue.
