Groundwire: the SIP softphone for your PBX or VoIP provider Groundwire is a SIP softphone app from Acrobits, a leader in VoIP and communication software since 2009. It delivers clear voice and video calls for personal and professional use, with an interface built for daily calling and none of the clutter. IMPORTANT, PLEASE READ Groundwire is a SIP client, not a VoIP service. You need service from a VoIP provider or PBX that supports standard SIP clients. Business calling features Groundwire carries the call handling you expect from a desk phone: - Group calls, for conferencing several people into one conversation. - Attended transfers, so you can announce a caller before handing the call over. - Unattended transfers, when the caller just needs the right extension. - Voicemail with notifications, so a missed call still reaches you. - Instant messaging, for the things that do not need a call. - Per-account settings, so one device carries several SIP identities cleanly. Works with your PBX or VoIP provider Groundwire is a universal client and true VoIP for PBX users. Teams run it as an Asterisk softphone, a FreePBX extension, or a 3CX endpoint, and it connects just as readily to hosted PBX systems and business phone providers. It also comes preconfigured for major providers, so setup takes minutes. Because it is a standard client, there is no lock-in: bring the account you already have, and Groundwire becomes the mobile extension of your PBX, with encrypted SIP calling on every network. On a team it is the business softphone dialer sitting on top of the PBX you already pay for. On your own it keeps a work line separate, or carries a desk extension in your pocket. Key features of the softphone - Audio on widely used codecs, Opus, G.729 and G.711 among them. - Video calls at 720p HD, carried by H.264 and VP8. - Private conversations with military-grade encryption, including TLS, SRTP, and ZRTP. - Low battery use thanks to efficient push notifications. - The VoIP dialer hands calls over between WiFi and mobile data without dropping them. - Custom call settings, UI, and ringtones per account. - 5G ready and compatible with most mobile operating systems. A softphone app without the fees Groundwire is a softphone for calling over WiFi and mobile data, with the business dialer features that usually cost a monthly fee. One payment, no subscription, nothing hidden: buy it once and it stays yours. Encryption sits inside that price rather than on top of it. Run a call center, manage a fleet of extensions, or keep a dependable sip phone for a home office. The same app covers all of it, without extra tiers. Download Groundwire and put a dependable SIP dialer on your phone, with Acrobits engineering and responsive support behind it.
