Recommendation E.123 specifies the format of telephone numbers assigned to telephones and similar communication endpoints in national telephone numbering plans. In examples, a numeric digit is used only if the digit is the same in every number, and letters to illustrate groups.
CAMEL Phase 1 defined only very basic call control services, but introduced the concept of a CAMEL Basic call state model (BCSM) to the Intelligent Network (IN). Phase 1 gave the gsmSCF the ability to bar calls (release the call prior to connection), allow a call to continue unchanged, or to modify a limited number of call parameters before allowing it to continue.
This means that to call another number within the same city or area, callers need to dial only a subset of the full telephone number. For example, in the NANP, only the seven-digit number may need to be dialed, but for calls outside the local numbering plan area, the full number including the area code is required.
A SIP address is written in user@domain.tld format in a similar fashion to an email address.An address like: sip:1-999-123-4567@voip-provider.example.net. instructs a SIP client to use the NAPTR and SRV schemes to look up the SIP server associated with the DNS name voip-provider.example.net and connect to that server.
A call detail record contains data fields that describe a specific instance of a telecommunication transaction, but does not include the content of that transaction. By way of simplistic example, a call detail record describing a particular phone call might include the phone numbers of both the calling and receiving parties, the start time, and duration of that call.
An ABI defines how data structures or computational routines are accessed in machine code, which is a low-level, hardware-dependent format. In contrast, an application programming interface (API) defines this access in source code , which is a relatively high-level, hardware-independent, often human-readable format.
The handset’s directory entry (in the “contact number” field) would contain the actual number of the person to call in case of emergency. [ 5 ] This language-independent recommendation preceded the popular "ICE" (In Case of Emergency) scheme introduced in 2005 to the English-speaking world.
Another sound-based application is call whispering, which is a message played to an agent after answering a call that can give them information about the call in advance based on the Caller ID, number dialed or route taken through the system. [6] Call management can also include directory programming for received calls.
