telephone number to forward calls to. The PHONE ADAPTER provides audio instructions to prompt

the user for a forwarding number and confirms that the requested service has been activated.

Call FWD – Unconditional

All calls are immediately forwarded to the designated forwarding number. The PHONE ADAPTER

will not ring or provide call waiting when Call FWD – Unconditional is activated.

Call FWD – Busy

Calls are forwarded to the designated forwarding number if the subscriber’s line is busy because of

the following; Primary line already in a call, primary and secondary line in a call or conference.

Call FWD - No Answer

Calls are forwarded to the designated forwarding number after a configurable time period elapses

while the PHONE ADAPTER is ringing and does not answer.

1.1.4.2.12. Anonymous Call Blocking

By setting the corresponding configuration parameter on the PHONE ADAPTER, the subscriber has

the option to block incoming calls that do not reveal the caller’s Caller ID.

1.1.4.2.13. Distinctive / Priority Ringing

The PHONE ADAPTER supports a number of ringing and call waiting tone patterns to be played

when incoming calls arrive. The choice of alerting pattern to use is carried in the incoming SIP INVITE

message inserted by the SIP Proxy Server (or other intermediate application server in the Service

Provider’s domain).

1.1.4.2.14. Speed Dialing

The PHONE ADAPTER supports speed dialing of up to eight (8) phone numbers or IP addresses. To

enter a telephone number speed dial using a touch tone telephone, the user dials a feature code

(*74), followed by a number (2-9), then the destination speed dialed target number. When the user

wishes to speed dial a target number, they press the corresponding speed dial assigned number

followed by the “#” (pound) key.

Users may also enter/review speed dials from User1/User2 web-pages. This interface or similar is

required to enter IP address targets.

1.1.4.3. PSTN Interworking

The PHONE ADAPTER is designed to provide a transparent interworking relationship with the PSTN.

Service providers can deploy the PHONE ADAPTER in such a way that PSTN endpoints – wired or

wireless – communicating with PHONE ADAPTER endpoints do so without modification to their

configuration or network settings.

The service provider may choose to deploy a multi-protocol VoIP network, much the same way the

PSTN supports multiple signaling schemes today. Most telecommunication providers operate

equipment that supports CAS or channel associated signaling, ISDN signaling and SS7 signaling.

When VoIP is introduced or used in the telecommunications landscape, it is likely that the service

provider will implement a signaling gateway that supports multiple IP Telephony protocols along with

legacy PSTN protocols. The signaling gateway is commonly referred to as a Softswitch.

Architecture and functionality can vary greatly amongst the different softswitch vendors. The

protocols used will depend on the types of connections that will be set-up across the service

provider’s network. If the provider is simply providing transport of calls to/from their network to

another provider’s network, but not originating or terminating calls with the endpoints, SIP will likely

be used for softswitch to softswitch communication.
