Problem in VOIP in internal network

Hi There

I have a problem with VoIP in the internal network. I have a VoIP VLAN on the switch and wrote a rule for VoIP on my firewall. Everything works well for the external network, but for the internal network, the phone rings but there is no audio. I created a rule for the internal source LAN with the range of IPs, the destination is the same LAN range, and I allowed all services, but it’s still not working.

Cheers
