Informacast Setup Help

[MacroConnect]

Hello all,

I have been attempting to set up Informacast Fusion with 3CX. I get as far as registering an extension within Informacast, but as soon as I make a call to the extension Informacast will answer but no audio will come through. With my attempts from working with support on Informacast, they said it is due to 3CX not sending an ACK to Informacast.

Has anyone been able to get this equipment to work? Does it make a difference that it is in the cloud versus onsite? Is there some equipment that needs to be in the middle of the 2 systems?

Generally a no audio issue is because of a firewall, or something else blocking certain ports. Have you successfully run the 3CX firewall Checker?
How are you calling from 3CX...though a VoIP provider trunk? If so, have you had any audio issues calling any other numbers?

I have no other issues with any other calls. Internally nor externally. Only with this system. Firewall checker passes everything. I even disabled the firewall on the cloud and locally for a few minutes to see if that was the case. Still same issue.

The system requires an ACK from 3CX during the call and 3CX does not send it. That is the issue I see happening.

I'm assuming you are placing am outgoing call to them. That being the case, would this be the ACK after they (supposedly) send a 200 OK?

Have you used something like Wireshark to confirm the SIP messaging being sent. It may be that 3CX is not responding because the are not receiving something to respond to.
