Hello,
Looking for assistance from the collective expertise of the community with regard to running a VOIP telephone via 4G
Scenario thus
An elderly friend (95) has recently moved into a care home. His faculties are failing somewhat so what I would like to replicate is his home phone next to his bed to allow for easy in/out calls on the normal traditional “land line” with which he is familiar.
Previously had FTTP (Zen - so had benefit of fixed IP) at his residence with his (previous) BT line ported to AAISP and connected via a Fritzbox 7530 His home extension wiring plugged directly into port on rear of Fritzbox, so just used standard phones around the house.
He does have a mobile (ID Mobile) on an unlimited calls/4Gb data contract £6pm rolling monthly but is struggling somewhat using the mobile phone. Potentially (I hope) this SIM could be used for the proposed VOIP 4G connection.
Kit wise we (obviously) have the Fritzbox 7530 and I also have a Netgear 4G LTE modem (LB2120) lying around which is functional.
The connection is very unlikely to be used for general internet browsing etc, so anticipate data usage and speed requirements low.
I understand that a key concern for VOIP functionality is NAT and CGNAT throws a further spanner into the equation. Only the main stream providers (EE, Three etc) seem to provide routable IPv4 addresses and charge a substantial premium for the privilege. The rest seem to be exclusively CGNAT.
I am aware that AAISP offer a L2TP service to circumvent the absence of a routable IPv4 and their light service looks promising and good value.

This potentially would work with the existing kit, apart from we need to have a L2TP client to connect to AAISP servers.
Unfortunately the Fritzbox seems to only accommodate IPSec and Wireguard clients, so it appears that replacement/additional hardware may be required. Note that I am attempting to keep costs low (we’re not in Draytek territory!)
Just wondering if anyone has come up with a functional solution (the simpler the better) and if so what was their solution?
Finally, I am not convinced given the location of the care home (L8 5XW) that IDMobile (Three) is the best provider mast wise and wonder if an alternative virtual provider on a different network may be a better bet. Is anyone able to advise what is likely to be the best provider for this location?
Needless to say, give the age of my friend, we are only looking for monthly rolling mobile contracts.
Cheers
Alan
