Voice Boards from Donjin Communication Technologies

Donjin has range of CTI products starting with 8 port analog cards to 8 E1, 240Port high density Voice boards.

They support Windows OS and as per their website and they support APIs of Dialogic 5.11 System Release fro DMV1200 boards! That seems to be an useful feature as many IVR Software are developed based on Dialogic APIs. Migrating from Dialogic to Donjin cards may be easier.
They also have single port and dual port SS7 Signaling boards. The signaling board and voice boards are connected through CTI cable just like Dialogic Boards.

Recently they have entered into an strategic agreement with one Indian Telecom Software Development Company Amdale.
Donjin Communication Technologies (“Donjin”), A leading manufacturer specializing telecom products, multi-media switches based in Shenzhen, China and Amdale Software Technologies (“Amdale”), A global developer of open architecture-based SCE (Service Creation Environment) building blocks framework for telecom applications, based in Gurgaon, India, have entered into a strategic understanding. As per news on www.donjin.com.

While I have not tried their boards or there is no price list given on their website, it looks like a cheaper alternative to Dialogic CTI Cards for lower density, normal IVR Software.

    Hi Shrikant,
    Looks interesting. Does your boards support Dialogic APIs like Donjin or you have your own API ?

  • Shrikant July 26, 2010, 2:35 pm

    Hi Uttam,

    We have our own API’s for any application development.

    let me know if you need any other information.
