asterisk version: 13.21
using VPN, local and remove both candidate type is the host.
Asterisk sends invite over WebSocket to SIPJs client
SIPJS client response with trying, ringing and 200 ok
SIP JS client retransmit again and again 200 OK as ack not received from call server.
As checked the asterisk sip logs: 200 ok doest received hence asterisk does not sends ack.
any idea why 200 OK not received at asterisk?
