Use a SIP Phone with a Workflow Application
When choosing a SIP phone for use with a Microsoft Unified Communications Managed API (UCMA) application, consider three options:
Microsoft Lync 2010 Phone Edition
Microsoft Lync 2010
Microsoft Lync 2010 Mobile
Understanding SIP Phones
A SIP phone can natively connect to the Internet through SIP instead of the Public Switched Telephone Network (PSTN). A softphone is a software program integrated within your computer to serve as a telephone, typically using a headset. SIP clients, such as SIP phones and softphones, require software to send and receive calls. A SIP phone or softphone is a SIP peer and an endpoint because it connects the caller to the host through a SIP line without requiring a gateway.
Lync 2010 Phone Edition
With Lync 2010 Phone Edition you can:
Make outbound audio calls to phone users, answer inbound phone calls, and make Voice over Internet Protocol (VoIP) calls.
Set call-handling options to forward calls to another number or contact, so you can retrieve calls on your mobile phone, for example, when you are not in the office.
Keep a record of all phone conversations in Microsoft Outlook messaging and collaboration client.
Make calls from wherever you are located, regardless of whether you are inside or outside a firewall.
Lync Client
With Lync 2010, a user can make an outbound call using their computer or a traditional desktop phone. For inbound calls, users can answer a call, redirect it to an alternate number or voice mail, or answer with an instant message.
Lync Mobile
Use Microsoft Lync 2010 Mobile to send an instant message.
