This guide explains how to use the Groundwire app on your smartphone
Setting Up Groundwire hostedPBX on Android

Setting Up a SIP Account on Android
SIP Account
Here you can see the configuration window. In the "Title" field, you can enter the name of your account, e.g., Test123 or whatever you like. In the "Username" field, enter the extension number defined on the hostedPBX. In the "Password" field, enter the password you set on the hostedPBX. The domain is the location where the client should register (hostedPBX). Here, you can enter the name of the PBX or its IP address. Both work exactly the same way. If you do not have this information, please contact your IT service provider or send us an email at customer.service@winet.ch.

Important Information
Multiple Registrations
Not all hPBX systems support multiple registrations. The Ayrix hPBX supports multiple registrations starting with version 5.0.
If you're unsure whether you're eligible for multiple registrations, feel free to contact us at any time at customer.service@winet.ch Contact us.
Ad Format
This is a phone setting, not a setting within the app itself. Every phone has its own settings for this. There are also differences among Android models. While a Samsung and a Xiaomi are similar, they aren't exactly the same. You'll have to figure out for yourself how it works on your phone.
