VOIP over 5G

Hi Everyone

I have decided to port my BT landline number to a VIOP provider and I will be connecting my VIOP phone via a 5G router.

I am in a pretty good 5G area in Central London. However, I have discovered from doing some tests that my connection is not 100% free of latency, jitter and packet loss.

I am hoping that someone on this forum will be expert enough to be able to answer this question.

I am guessing that the three issues I have mentioned above are caused by one of, or a combination of, the following three things:

1. Radio signal interference between my 5G router and the mast.
2. Too many people connecting to the same mast.
3. Congestion on the fibre network the mast is connected to.

To what extent are each of the above three things causing the latency, jitter and packet loss?

I would be very grateful to anyone who can provide me with a detailed understanding of this.

Thank you very much.

Kind regards

Tim

A lot of the time the problems stem from oversold mast or poor backhaul (mast's connection to the mothership). There's little one can do except find a better spot for the router.

In addition to this, do keep in mind that VoIP can break over LTE/5G. For example VoIP has loads of problems on EE, it's basically unusable.
I works on Three, at least for now.
For best results you'd be using some sort of VPN, perhaps like AAISP's l2tp offering or anyone else who doesn't employ CGNAT and messes up UDP ports.

I switched to VoIP over 4G (Three, no 5G where we live) at the beginning of the year and it has been working very well without any glitches. Inbound via A&A, outbound on FreeVoipDeal.
VoIP only needs about 100kb/s in each direction, which should be available even in busy cells.

I use VOIP over a very marginal 5G and when tested it seems to work fine. I do not use it very often though. NR5103E as per sig' below. Three business data sim.
