Can I connect my employees' iPhones to our office phone system?
Yes. If your office phone system is SIP-based, including hosted PBX, on-premise Asterisk/FreeSWITCH, 3CX, or FreePBX, employee iPhones can be connected as SIP extensions. Each iPhone runs a softphone app that signs in with the employee's SIP credentials and connects to your PBX. Small teams can each install a retail app like Groundwire; operators deploying to dozens or hundreds can push a branded app with Cloud Softphone.
How do I forward my office phone to my mobile when I'm out?
Use Groundwire to register your office extension directly on your phone. Your mobile becomes the extension, not a forwarded destination, so you keep the full PBX feature set on the go: transfer back to a colleague, conferencing, internal directory access, and office caller ID on callbacks. Traditional call forwarding only sends office calls to your cell number, and you lose many of those PBX features in the process.
How do I get my team to receive calls from our business phone system on their personal phones?
Create a SIP extension in your PBX for each team member, then have them install Groundwire ($9.99, one-time purchase) and enter the extension credentials. Each personal phone then registers as a full business extension, with push notifications so calls ring even when the app is closed.
Is there an app that lets me make and receive calls from my business number on my iPhone?
Yes. Groundwire is an iOS SIP softphone that lets you make and receive calls on your SIP-based business number for a $9.99 one-time purchase. Enter your SIP credentials from your VoIP provider, and your iPhone rings with your business number.
