1.1.4.1. Basic 
Services 
1.1.4.1.1. 
Making Calls to PSTN and IP Endpoints 
This is the most basic service. When the user picks up the handset, the PHONE ADAPTER provides 
dial tone and is ready to collect dialing information via DTMF digits from a touch tone telephone. 
While it is possible to support overlapped dialing within the context of SIP, the PHONE ADAPTER 
collects a complete phone number and sends the full number in a SIP INVITE message to the proxy 
server for further call processing. In order to minimize dialing delay, the PHONE ADAPTER maintains 
a dial plan and matches it against the cumulative number entered by the user. The PHONE 
ADAPTER also detects invalid phone numbers not compatible with the dial plan and alerts the user 
via a configurable tone (reorder) or announcement. 
1.1.4.1.2. 
Receiving Calls from PSTN and IP Endpoints 
The PHONE ADAPTER can receive calls from the PSTN or other IP Telephony subscribers. Each 
subscriber is assigned an E.164 phone number so that they may be reached from wired or wireless 
callers on the PSTN. The PHONE ADAPTER supplies ring voltage to the attached telephone set to 
alert the user of incoming calls. 
1.1.4.2. Enhanced 
Services 
Enhanced Services are provided in addition to Basic calling services and accessed by way of a 
touchtone phone through a series of menus.  Since the service enabled by the PHONE ADAPTER 
are Internet in nature, these enhanced services can be made better by offering users a web browser 
based interface to control certain aspects of some or all services. 
1.1.4.2.1. Caller 
ID 
In between ringing bursts, the PHONE ADAPTER can generate a Caller ID signal to the attached 
phone when the phone is on-hook. 
Calling Line Identification Presentation (CLIP) 
Some subscribers will elect to always block their Caller ID information, yet there may be a 
circumstance where sending Caller ID information for a particular call is desired, i.e. trying to reach a 
party that does not accept Caller ID blocked calls.   
The subscriber activates this service to send his Caller ID when making an outgoing call. To activate 
the service, the subscriber enters the corresponding * or # code prior to making the call.  This service 
is in effect only for the duration of the current call. 
Calling Line Identification Restriction (CLIR) – Caller ID Blocking 
The subscriber activates this service to hide his Caller ID when making an outgoing call. To activate 
the service, the subscriber enters the corresponding * or # code prior to making the call.  This service 
is in effect only for the duration of the current call. 
1.1.4.2.2. Call 
Waiting 
The subscriber can accept a call from a 3rd party while engaging in an active call. The PHONE 
ADAPTER shall alert the subscriber for the 2nd incoming call by playing a call waiting tone. 
Disable or Cancel Call Waiting 
By setting the corresponding configuration parameter on the PHONE ADAPTER, the PHONE 
ADAPTER supports disabling of call waiting permanently or on a per call basis. 
Call-Waiting with Caller ID 
In between call waiting tone bursts, the PHONE ADAPTER can generate a Caller-ID signal to the 
attached phone when it is off hook.
