Hello to everyone, i have a very strange problem.
When someone is calling me, the first time, i can’t hear him, but if they call me 1 minutes after, then i can hear him ?
I really don’t know why i can’t hear the first time they call me, but the second will work ?
This is not port issues, my VPS provider told me they not block these port…
Any help ?
I am running my FreePBX on VPS, but my IP phone at my shop is on my network, so do i have to forward port on my own network for the Ip phone or not…
My problem seem to be port problem, but here my VPS port…
