Thanks for the response guys. &nbsp;I talked to Shoretel and they said they do support SIP phones but only 7-8 basic functions. <br />
<br />
I will give you a heads up on what I come across.

Hello all. <br />
<br />
We currently have a hosted VoIP system using Cisco phones that are SIP enabled.<br />
<br />
We want to go back to PBX systems so I was wondering do you know of any PBX systems that will support the Cisco IP phones?<br />
<br />
I know Asterisk does, how about some of the other mainstream guys like Shoretel or Mitel?<br />
<br />
Thanks!!

Which IP/PBX systems can support Cisco IP Phones with SIP Enabled?

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
