Configuration Details
The configuration will be done in only 3 steps. Once you have downloaded GroundWire from Google Play/Apps Store, you will need to start the application.
On the initial start up for Android, the Acrobits Groundwire App will require some rights such as access to your microphone and call information to be able to fully use this application.
Once this is done, you have to create your first SIP account. In this section, VoIP.ms has been certified by Acrobits and we are in the provider list. Simply type "VoIP.ms" into the upper search box and click on it to start the configuration.
In this section, you will need to fill the fields with your main account/sub account information. You will also need to specify the server that you want to be registered on.
- Title: You will be able to rename this field if you plan to use more than one account on this apps.
- Username: You main SIP account or sub account username
- Password: The password you set for the account / sub account
- Domain: One of VoIP.ms multiple servers, you can choose the one closest to your location.
- Advanced Settings: Secure Calls: Set to "Disabled" unless you already have "Encrypted SIP Traffic" set to yes in your main Voip.ms account, and the sub account advanced settings also set to "Encrypted SIP Traffic" - Yes.
- Advanced Settings: Transport Protocol": Set to UDP, or if using Secure Calls, then set to "tls (sips)"
Finally, click on the upper right "Save" button and you will be able to start using your VoIP.ms account with Acrobits GroundWire softphone apps.
If you need assistance during the configuration, don't hesitate to contact VoIP.ms support.
Call Encryption - TLS/SRTP
To use encrypted calls (TLS), once your main Voip.ms account, or any sub accounts have been properly configured, the following setting must be set in Groundwire:
- Open the advanced settings of the account to configure for TLS:
- Settings -> Accounts -> (select the account) -> Advanced Settings
- Once in Advanced Settings:
- Set Transport Protocol to “tls (sip)”
- Go in Secure calls setting.
- In the SDES (RFC 4568) section, set both Incoming Calls and Outgoing Calls to “Required”.
- Validate all these changes, and your secured call connection (TLS) should register as expected.
Outbound CallerID Name
Under the apps settings, click on "Accounts" then on the SIP account you need to add an Outbound Caller ID to. Click on "Advanced settings". Scroll down to "Caller Identification".
Voicemail settings
If you would prefer to have easy access to your Voicemail instead of dialing *97/*98, you can set your voicemail number directly in your settings. Doing this, you will be able to click directly on a "voicemail" button directly from your dialpad when you have a voicemail.
Under the app's settings, click on "Accounts", then the SIP account you need to add a Outbound Caller ID. Click on "Advanced settings". Scroll down to "Voicemail Settings"
Codec G.729a
The codec G.729a is an advanced biterate codec that requires less bandwidth, ideal if you have only access to a 3G network. This codec requires you to purchase the license to be able to used it. To do so, you need to go on your in-apps settings, above "Application settings" click on "Complement", then under Codecs "G.729 Codec of Annexe A", you will be able to purchase it.
