Inbound CNAM lets you see the name of the person or company who is calling before you answer. We use several national telecom databases to lookup the name before we send the call to your device. We now offer CNAM as a flat-rate monthly fee versus the standard per “dip” or lookup charge. Note: CNAM is only provided if the caller’s name is listed in the national database.

Outbound Caller ID with Name allows you set the name people see on their caller ID when you make outbound calls. There is a one-time charge of $10 for each DID number that is published to the national CNAM (aka LIDB) database.

All domestic calls (USA, Canada, and Puerto Rico) are rounded to the nearest six second (6/6). International calls have a thirty second minimum once connected and then are rounded to the nearest six second (known as 30/6).

Vitelity is 100% pre-paid. At the time of signup, you will provide a credit card in which we will charge your card an initial $35 pre-pay (to create an initial positive account balance). Once you have access to your account management portal you will be able to deposit money into your account using your credit card or Pay Pal at any time.

See the Auto Replenishment and Notifications information on this page for information on how to keep your account funded.

SIP (Vitelity default) – Session Initiation Protocol is a signaling protocol used to create, manage and terminate sessions in an IP based network. A session could be a simple two-way telephone call or it could be a collaborative multi-media conference session. This makes it possible to implement services like voice-enriched e-commerce, web page click-to-dial or Instant Messaging with buddy lists in an IP based environment. Don’t worry if you don’t know about these services. You don’t need to know them before you learn about SIP.

As related to voice, a codec is the process of compressing and decompressing voice data. Vitelity currently supports the following codecs:

G.711(Vitelity default)

G.711 is a high bit rate (64 Kbps) ITU standard codec. It is the native language of the modern digital telephone network.

Although formally standardized in 1988, the G.711 PCM codec is the granddaddy of digital telephony. Invented by Bell Systems and introduced in the early 70′s, the T1 digital trunk employed an 8-bit uncompressed Pulse Code Modulation encoding scheme with a sample rate of 8000 samples per second. This allowed for a (theoretical) maximum voice bandwidth of 4000 Hz. A T1 trunk carries 24 digital PCM channels multiplexed together. The improved European E1 standard carries 30 channels.

There are two versions: A-law and U-law. U-law is indigenous to the T1 standard used in North America and Japan. The A-law is indigenous to the E1 standard used in the rest of the world. The difference is in the method the analog signal being sampled. In both schemes, the signal is not sampled linearly, but in a logarithmic fashion. A-law provides more dynamic range as opposed to U-law. The result is a less ‘fuzzy’ sound as sampling artifacts are better suppressed.

Using G.711 for VoIP will give the best voice quality; since it uses no compression and it is the same codec used by the PSTN network and ISDN lines, it sounds just like using a regular or ISDN phone. It also has the lowest latency (lag) because there is no need for compression, which costs processing power. The downside is that it takes more bandwidth then other codecs, up to 84 Kbps including all TCP/IP overhead. However, with increasing broadband bandwidth, this should not be a problem.


G.729 is an ITU standard codec

It offers toll quality speech at a reasonably low bit rate of 8Kbps. However, it is a rather “costly” codec in terms of CPU processing time, therefore some VoIP phones and adapters (notably the Linksys/Sipura/Cisco brands) can only handle one G.729 call (channel) at a time. This can cause calls to fail if the user attempts to use three-way calling, or place simultaneous calls on both lines of a two-line device, and G.729 is the only allowed codec.

Use of this codec in a product requires licensing. Licenses can be purchased from a company that re-sells G.729 licenses such as Digium.


GSM (Global System for Mobile communications) is a cellular phone system standard popular outside the USA.

GSM includes a codec, often just referred to as the GSM when discussing codecs.

The original ‘Full Rate’ GSM speech codec is named RPE-LTP (Regular Pulse Excitation Long-Term Prediction). This codec uses the information from previous samples (this information does not change very quickly) in order to predict the current sample. The speech signal is divided into blocks of 20 ms. These blocks are then passed to the speech codec, which has a rate of 13 kbps, in order to obtain blocks of 260 bits.
