US calls not coming through

redsox9 — Fri, 02 Jan 2026 23:22:49 GMT

Using VOIP with Plusnet Hub 2, a Grandstream adapter and the Andrews & Arnold service, I notice that phone calls from the USA are being cut off after one ring. What can I do to prevent this?

Waiting to hear from A&A Support but would be grateful for your thoughts.

@redsox9 I cant quite see why calls from the US would be treated any differently by either A & A or your Grandstream.

My guess (and its just a guess!) is a poor internet connection to the US endpoint.

A SIP log from the Grandstream (if it can provide one?) or a Wireshark trace may provide some insight.
