An end user can switch from one softphone to another during an active call without putting the call on hold. The switch happens between VoIP applications registered to the same account. The other party remains connected throughout.
EXAMPLE
On his way home, John, a sales manager, receives a call from a customer on his mobile app. As the conversation continues, John arrives home and logs into the web app on his laptop. The web app notifies him of an active call on his account, and John clicks “pull call” to switch the call to his laptop. In the background, the web app sends a SIP request to PortaSwitch to pull the ongoing call with the customer to the web app. The call from the web app starts, using the same call ID and tags, and the mobile app is disconnected from the call. John continues the conversation from the laptop, while the switchover is seamless for his customer. PortaSwitch considers this switchover as a single call, and the call history reflects it as a single call detail record.
Benefit
Users can have uninterrupted conversations while using multiple devices.
