About SIP Addresses
SIP addresses are used to identify users within a network just like you would use a phone number or an email address to contact a
friend or colleague.
Like email addresses, SIP addresses are a type of uniform resource identier (URI) that includes two user-specic parts, a user ID or
extension and a domain or IP address. Together with a prex and the @ symbol, they make up a unique address. For example, if
Caesar of ancient Rome had both an email address and a SIP address, they would be mailto:caesar@ancientrome.it
and sip:caesar@ancientrome.it respectively. For local peer-to-peer calls only the IP address is required. For more
examples and descriptions, see below.
SIP addresses are also known as SIP URIs or, in some cases, SIP numbers. For more information, see the PBX’s and service provider’s
instructions.
Example
sip:192.168.0.90
sip:3468@172.25.33.142
sip:3468@voipprovider.com

The DTMF Settings Page
Dual-Tone Multi-Frequency (DTMF), also known as touch-tone, is a signaling system used by telecommunication devices such as
telephone handsets, switch centers, door stations, and other communication devices.
DTMF is used to remotely control other devices. When you press a button on a keypad, a DTMF packet is created and sent to the other
device. The receiving device decodes the packet, identifying what you want to control and which action you want it to take.
When a SIP account is added, a DTMF conguration associated with the new SIP account is automatically created. The DTMF Settings
page presents and enables access to the DTMF congurations for all peer-to-peer and registered SIP accounts.
