ShoreTel Remote phone system

Remote Phone

Overview

As part of the ShoreTel Sky phone system, you can use an IP phone from a remote location, such as a home office or any location with a broadband connection to the Internet. A remote phone enables you to call associates in different offices as if you were calling from your desk in your main office. In addition, you have access to all of the features of the phone, including the ability to access voicemail and directly dial extensions. The remote phone functionality of ShoreTel Sky's service is ideal for salespeople and employees who work from home or from remote locations.

Note: If your location is an Off-net Location, then your phones are considered remote.

Requirements

In order to operate a remote phone in the ShoreTel Sky phone system, you must have the following:

• An "always-on" broadband connection. (Data rate must be at least 128 kbps, which most cable modems provide.)
• A router to provide your IP phone with a private IP address.
• A power supply for your IP Phone.
• Cat 5 Ethernet cable to connect your IP Phone to your router.
• An IP Phone supported by ShoreTel
• A managed profile

You or your IT Department are responsible for the purchase or maintenance of any cables, routers, hubs, Network Address Translation (NAT) devices, PC network cards, modems, switches and any required network equipment. Your Phone Manager is responsible for the purchase of any IP phones, power supplies and phone profiles. The specific equipment required for each installation will depend on your Broadband Internet Service Provider.

Setup

Review and confirm the following information before proceeding:

• You have met all of the remote phone requirements.
• The broadband internet connection is working.
• You have verified the appropriate ports on your firewall have been opened outbound (see Firewall Settings below).
• Your IP phone is powered and plugged into your network as shown in the Network Diagrams section below.
• Review the "Off-Net Firewall Best Practices" section of the Data Network Best Practices Guide.

After you have confirmed the requirements listed above, the last step is confirming that the TFTP/Config Server IP address on your phone is set correctly. Note that following:

• "Config Server" refers to IP address settings configured on all ShoreTel phones
• "TFTP" refers to IP address settings configured on all Cisco phones

In the list below, click the link that corresponds to your IP phone model. Review the instructions for accessing the TFTP/Config Server setting on your phone to make sure the setting is correct. See the TFTP/Config Server article for a list of all instances (clusters) and the associated TFTP/Config Server IP addresses utilized in the ShoreTel Sky phone system. Compare the setting on your phone with the "TFTP/Config Server 1" setting listed next to the instance (cluster) associated with your account. Note that Authorized Contacts can view the "Instance" for their account in the Account Details screen. See the Account Facts section of our Account Details article for more information.

Firewall Settings

To enable phones and the Phone Assistant application to communicate with the ShoreTel Sky phone system over a broadband internet connection, firewalls must be configured to allow outbound and inbound traffic to and from the ports listed below.

• TCP 12000 SCCP
• TCP 12001 SCCP/HTTP
• TCP/UDP 5060 SIP
• TCP 5061 SIP
• TCP/UDP 15061 SIP
• TCP 5443 and 5448 CAS
• UDP 69 TFTP
• UDP 16384 through 37000 RTP Media Server
• TCP 80
• TCP/UDP 443
• TCP Proxy.m5net.com:8XXX (where 8XXX is the Server/API Port Number for your organization's account as explained in the TFTP/Config Server article)

Note: Depending on your firewall type, you may not be able to specify individual ports or port ranges. In this situation, we recommend opening all outbound/inbound traffic for your instance (cluster). See the TFTP/Config Server article to identify the "Primary TFTP/Config Server 1" IP address and "Server/API Port Number" associated with the instance assigned to your organization's account. Note that the instance is the server where all of your organization's phones are connected.
