Turn Traditional Telephones Into IP

Endpoints

The cost-effective, standards-based Cisco ATA

187 Analog Telephone Adaptor protects your

existing analog telephone investment while

delivering true voice-over-IP (VoIP) terminations.

Simply connect traditional analog devices to

the Cisco ATA 187 and a traditional telephone

becomes an IP endpoint. You can use the Cisco

ATA 187 in both businesses and residences

worldwide, where it:

• Delivers clear, natural-sounding voice quality

• Supports two voice ports, each with its own

independent telephone number

• Provides a single RJ-45 10/100 BASE-T

Ethernet port

• Can use existing Ethernet LANs in addition to

broadband pipes such as DSL, ﬁxed wireless,

and cable modem deployments

When telephones are connected to the Cisco

ATA 187, companies can take advantage of many

cost-saving, productivity-building IP telephony

applications, including:

• User conﬁguration

• Full-duplex capability

• Central provisioning for ease of administration

• Session Initiation Protocol (SIP) support,

which allows interoperation with Cisco Uniﬁed

Communications Manager

• SIP services such as dynamic IP address

assignment, VLAN conﬁguration, user

authentication, etc.

• Fax support so you can send faxes cost-

effectively over the IP network

The Cisco ATA 187 enables secure media and

signaling support through Secure Real-Time

Transfer Protocol and Transport Layer Security

(SRTP/TLS) over SIP. The adaptor is also

ﬁrmware-upgradable.
