CHAPTER 15
VoIP
15.1 Overview
Use this chapter to:
• Connect an analog phone to the LTE Device.
• Make phone calls over the Internet, as well as the regular phone network.
• Configure settings such as speed dial.
• Configure network settings to optimize the voice quality of your phone calls.
15.1.1 What You Can Do in this Chapter
These screens allow you to configure your LTE Device to make phone calls over the Internet and
your regular phone line, and to set up the phones you connect to the LTE Device.
•Use the SIP Service Provider screen to configure the SIP server information, QoS for VoIP
calls, the numbers for certain phone functions (Section 15.2 on page 123).
•Use the SIP Account screen to set up information about your SIP account, control which SIP
accounts the phones connected to the LTE Device use and configure audio settings such as
volume levels for the phones connected to the LTE Device (Section 15.3 on page 129).
•Use the Phone Device screen to control which SIP accounts the phones connected to the LTE
Device use (Section 15.5 on page 133).
•Use the Region screen to change settings that depend on the country you are in (Section 15.6
on page 134).
•Use the Call Rule screen to set up shortcuts for dialing frequently-used (VoIP) phone numbers
(Section 15.7 on page 134).
You don’t necessarily need to use all these screens to set up your account. In fact, if your service
provider did not supply information on a particular field in a screen, it is usually best to leave it at
its default setting.
