Looking for a bit of help. Working on a 7100 with the newest software, connection with softphone and though it registers just fine, I have no audio. Ports are all forwarded. The firewall is a Meraki MX.

Anyone with experience on that platform?

It's possible that the meraki thinks the voip traffic is a dosb attack and is blocking the traffic.
Rtp is a large number of udp packets, this could look like ados attack. I've had some cheap netgear routers do this.

Try running wireshark on the pc end and see if you can see the voip traffic.

You do have the correct public ip configured on the system/oas card? This doesn't matter as much with sip but does with ip/soft phones

Figured it out. This Muppet right here forgot to set the private with public and enter the address.

Sorry to waste the bandwidth.....
