Troubleshooting

Start with resource status:

kubectl -n telephony get networkprofile,sipgateway,mediarelay,asteriskpool,sipuser,siptrunk,callscope,dialpolicy,callroute
kubectl -n telephony describe sipgateway main
kubectl -n telephony logs deployment/kubevoip-kubevoip

For one-way audio, check RTPengine Service addresses, firewall rules, and RTP port forwarding. SIP and RTP public ports must match the private ports.
