Thanks very much. I really can't remember much voip or volte settings in the router configurations but I'll check again and try some of your tips.Ref using the RJ11 socket on the back for phonecalls using a normal phone with an adaptor/converter.
There are 2 ways to use the socket.
1. As VOIP, there may be a voip setup page in the router configuration, use a free VOIP provider like Sipbasic and there is only a charge for outgoing calls all incoming are free and you can be assigned a local phone number. I ported accross my old BT number. No sim minutes are used. Voip is not in all firmwares and Three was an issue for a few months with the phone not registering on Sipbasic all the time.
2. Using the sim minutes (again firmware dependant)
For it not to revert to 3G you need to access the VoLTE settings in the router configuration and turn VoLTE on, not all firmwares have this and also not all masts can handle VoLTE.
On my B715 I have both Voip and VoLTE on the router configuration. With VOIP not setup and before VoLTE was enabled on the local mast with a handset plugged in if I used the handset the connection dropped to 3G when making or receiving a call. This affects the download speeds but the timelag dropping back to 3G mean't it took 30 secs for a dial tone to appear and the call was very laggy. VoLTE solved all of this.
The speeds I'm getting are pretty impressive by UK standards so I'm hoping the cell im hanging off is modern enough to support such settings.
