Same issue here… Been troubleshooting internally for a few days. Trying to determine if its a Vital problem or Yealink problem. My tests are inconclusive so far. My environment is difficult to troubleshoot as I use the VPN client on the phones. All the SIP traffic is in the tunnel. So PCAP is useless.
Any input as to what may be causing this would be greatly appreciated.
There has not been any change here. My customer is living with it but it does not look good on the system. I’ve had multiple issues BLF included with PJSIP which we are forced to use now.
