Innovation for Tomorrow and the day after.

This is a period of vivid change in communications. Innovation in technology, united with elemental changes in both existing business models and the business environment, are compelling a bold new architecture for application and service delivery. The emergence of the Internet was the genesis of this change, which hastened with the establishment of the World Wide Web consummated by the introduction of new standards that brought the best of voice communications to this IP/Web architecture.

The acceleration and innovation of new standards and technologies associated with the WWW are implicating every type of communications. aaramb has amalgamated the consequence of these technology and business process changes into a all-encompassing vision that has been termed the Communication Delivery Architecture (CDA). This architecture will alter the way communications services are generated forever and drive vital changes to the networks that are built to deliver these services. Those who initiate these changes will be highly successful, while those that do not are putting their very survival at risk.

IP Telephony, also known as Voice over IP (VoIP) or Internet Telephony, is technology which uses IP-based data networks to transmit telephone calls. IP (Internet Protocol) is the standard used by the Internet and private intranets for sending data packets. Voice from the telephone trunk is digitized, compressed (usually, because of the limited bandwidth of the Internet), and sent across the network where the process is reversed.

Gateways are switches which connect telephone trunks to the data network. An IP telephone call usually involves two Gateways one at the end of each call (a ‘local’ call could also be made if both phones were connected tot the same switch). Standards are essential - both Gateways must speak the same digital language in order to successfully complete a call.

Aaramb is pursuing its ongoing research in designing H323/SIP/GSM based protocol generalizer that address the need of convergence between heterogenous Communication Delivery channels.

H.323 Standard: The H.323 standard specifies how data calls should be connected and transmitted over an IP network.

GSM and G732.1 Codecs: Codecs (compressors/decompressors, also called coders) compress voice data so that it can be efficiently transmitted on the data network. GSM is 8 kHz, 8-bit PCM, similar to the format used internally by the public phone network. The GSM data rate is 64 kbps. G723.1 provides highly efficient compression, giving data rates of either 5.3 of 6.3 kbps - 10 times better, but still with clearly understandable speech transmission. Microsoft, Intel, Netscape, Dialogic and other heavyweights are backing G723.1.
