Software Specifications
Cisco ATA SIP services	• IP address assignment: Provided by DHCP or statically configured • Cisco ATA configuration through Cisco UCM configuration interface • VLAN configuration • Cisco Discovery Protocol • Low-bit-rate codec selection • User authentication • Configurable tones (dial tone, busy tone, alert tone, reorder tone, and call-waiting tone) • Dial plans • SIP proxy server redundancy • Privacy features • Domain Name System (DNS) service (SRV) support • User-configurable, call waiting; permanent default setting • Comfort noise during silence period when using G.711 • Advanced audio mode • Caller ID format • Ring cadence format • Silence suppression • Hook-flash detection timing configuration • Configurable on-hook delay • Type of service (ToS) configuration for audio and signaling Ethernet packets • Debugging and diagnostic tools
SIP services	Cisco ATA supports the methods listed here (for more information, refer to RFC-3261): • REGISTER • REFER • INVITE • BYE • CANCEL • NOTIFY • OPTIONS • ACK • SUBSCRIBE
Supplementary services	• Caller ID • Call-waiting caller ID • Voice-mail indication • Conference call • Call waiting • Call forwarding • Calling-line identification • Unattended transfer • Attended transfer • Shared line • Speed dial • Meet me • Pick up • Redial
Other supported protocols	• IEEE 802.1Q VLAN tagging • Cisco Discovery Protocol • DNS • DHCP • Internet Control Message Protocol (ICMP) • IP • Real-Time Transport Protocol (RTP) • TCP • Trivial File Transfer Protocol (TFTP) • User Datagram Protocol (UDP)
Fax services	The Cisco ATA supports two modes of fax services, in which fax signals are transmitted using the G.711 codec: • Fax pass-through mode: The mode enables receiver-side called-station-identification (CED) tone detection with automatic G.711A-law or G.711μ-law switching. • T38 fax relay mode: The T.38 fax relay feature enables devices to use fax machines to send files over the IP network. In general, when a fax is received, it is converted to an image, sent to the T.38 fax device, and converted back to an analog fax signal. T.38 fax relays configured with voice gateways decode or demodulate the fax signals before they are transported over IP. Note: Success of fax transmission depends on network conditions and the fax modem response to these conditions. The network must have reasonably low network jitter, network delay, and packet loss rate.
Voice codecs supported	• G.711μ-law • G.711A-law • G.729 • G.729A • G.729B • G.729AB
SRTP/TLS	• SRTP secures voice conversations on the network and provides protection against replay attacks. • TLS is a cryptographic protocol that secures data communications such as email on the Internet. TLS is functionally equivalent to SSL.
VoIP specifications	• LAN port: One RJ-45 10/100BASE-T Fast Ethernet port • Quality of service (QoS): Precedence setting and differentiated services code point (DSCP)
Call progress tones	Configurable based on network locale
Line-echo cancellation	• Echo canceller for each port • 8-millisecond (ms) echo length • Nonlinear echo suppression (echo return loss [ERL] greater than 28 dB for f = 300 to 3400 Hz)
