One of the concerns I would have for the callers at the remote site is emergency or 911 calling. &nbsp; Since they have no ShoreTel switch, they will either connect to your HQ switch or the other site depending upon the phone address map. &nbsp; If a user at the remote site attempts to call for emergency services, the address displayed would not be that of the remote caller.

We have Shoretel running across 2x sites at present. &nbsp;Head Office and a remote site (with no dhcp servers). &nbsp;<br />
I have a third site that replicates the same setup as head office, apart from there not being any shoretel switches, director etc at this site. &nbsp;<br />
Is it possible to use dhcp scope, helper etc to get a local voice vlan ip and point the phone using the 156 dhcp option to point back across the vpn to head office?<br />
<br />
The switch knows about the 2x vlans and gateway will be the switch. &nbsp;I can route between the 2x vlans. &nbsp;will just need to tweak the firewall(s)..<br />
<br />
Thanks

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).

Voice Over IP

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
