Yealink Handsets on LTE Connections
Problem
- LTE service has intermittant connection. Reconnects and gets different IP
- Online Sip provider registration is not updated with new IP.
Suggestions
Note this is not proven
- On LTE router
- Configure "unrestricted" APN. (Must be supported by upstream LTE Network Service)
- On Yealink Phone
- Configure "Account" "Advanced" "Keep Alive Type" "Notify"
- Configure "Network" "NAT" "ICE" "Active" "Enabled"
