Hello Folks, We have a client team working from our office, utilizing Cisco AnyConnect VPN on our guest VLAN. The issue is that during both inbound and outbound calls, the call rings and can be answered; however, there is no audio. Approximately 8 seconds later, the call disconnects as a failure. The client VPN uses split tunneling, where SIP signaling is routed via the VPN, but once the call is established, media is transmitted through the local router and onto the internet. Initially, there were numerous retransmissions observed in the pcap targeting the team's destinations. After whitelisting one client, these retransmissions disappeared, but the issue persists. Any advice or suggestions on resolving this would be greatly appreciated.
