Project Name

With overwhelming response from the telecom fraternity across the globe we are eager to finalise and  finish specs and work on core areas.
Whilst working on the same we now earnestly request you people to suggest rather christen a name for our “open source 16 e1/t1 telecom card

Applications that would be supported by Opensource 16 e1/t1 telecom card

List of all applications that are possible using open source telecom card

Data :

    *  Monitoring solutions (In roamer , out roamer , Traffic Management) etc
    *  USSD
    *  SMSC
    *  LBS
    *  INAP/Camel Based applications
    *  Virtual HLR
    *  Sigtran Signaling Gateway
    *  ss7 Signaling Gateway

Voice :
    * IVRS
    * IBD (inbound Dialers)
    * OBD (Outbound Dialers)
    * CRBT
    * VOIP

Video :   
    * Video IVRS

Software for Opensource 16e1/t1 Telecom card

it would take lot if time to develop all the stacks mentioned below either we can consider existing open source stacks or 3rd party commercial options like aricent , ccpu or netbricks  which could help in faster roll out


some parts are patented(audio and video codecs)  and can never be made open source such parts we have to think on how to get the tie up

SS7 :  MTP1/2/3 , ISUP , TCAP, MAP , INAP , CAMEL 

sigtran : M2UA , M3UA

ISDN : euro ISDN

3G-H324M :  compliant to existing 3gpp protocols


Driver : channel driver to integrate various open source call manager , HDLC

Audio Codecs : G711 , echo cancellation , DTMF , G729 , G723

Video Codecs : H264 , H263

we are mentioning all the areas of effort , later it will be easy to distribute between interested contributors
