Dialogic(R) Diva(R) SoftIP use cases

Dialogic(R) Diva(R) SoftIP use cases

Partial or full migration of existing installation and application environment to IP

One existing application with configuration can be migrated to IP environment is case phone numbers, media processing features and supplementary services are mapped (translated) between one use in IP network and one expected by developed in E.1/T.1/S0/PSTN application.

To achieve this mapping and translation softIP uses following techniques:

mapping between used by application phone numbers CPN/CiPN (DID, extensions, MSN) and SIP addresses

• for incoming calls mapping of SIP urls to CPN/CiPN/Redirection numbers

• for incoming calls mapping of SIP urls to CiPN and registering of SIP urls

• for outgoing calls mapping of CPN to SIP url to create call using default outbound proxy

• for outgoing calls mapping of CPN to SIP url and outbound proxy

translation of basic call signaling and supplementary services protocols between SIP and ISDN signaling protocols

• Dialogic(R) Diva(R) translates SIP signaling messages to ISDN QSIG messages which are routed and processed by softIP using one virtual ISDN network. This translation allows to achieve high level of compatibility to existing application uses same QSIG implementation as Dialogic(R) Diva(R) hardware
  • same source code
  • same state machines
  • same coding of messages
    

• allows to use any other supported by Divalogic(R) Diva(R) ISDN protocol instead of QSIG, but this is suggested to use QSIG as most flexible and best suited for this purpose

• if required provides access to SIP signaling to application

conversion of media protocols between used in IP and ISDN environment

• softIP provides support for multiple voice codecs and performs transcoding between expected by user application G.711 aLaw/uLaw byte stream and used at IP side RTP packet stream with one of supported payloads

• G.711 aLaw/uLaw, G.729, G.723 32k, GSM, iLBC

• if required softIP provides access to compressed IP data and RTP data to user application

• softIP uses T.38 and clear channel fax to provide to user application same T.30 capabilities and same support for formats of fax document media as in case of used in ISDN environment Dialogic(R) Diva(R) hardware

• V.34 Fax with 33600 Bps
  

• Provides high level of compatibility with by use of same T.30 implementation as Dialogic(R) Diva(R) hardware

• V.34 (33600 Bps) clear channel fax

• Provides high level of compatibility by use of the same fax modulation and T.30 implementation as Dialogic(R) Diva(R) hardware

• Supports line interconnect (conferencing between different types of peer)

• Between IP peers

• Between IP and ISDN (E.1/T.1/S0/POTS) peers

• Use of virtual E.1/T.1 interfaces

• To ensure compatibility with existing application which are not supporting interfaces with more then 31 channels softIP present available (licensed) channels as number of virtual E.1 (T.1) interfaces every with not more then 30 (23) bearer channels

• less 30 channels results in one virtual fractional E.1 interface

• 120 channels results in 4 x virtual E.1 interfaces

• Reuse of existing device drivers and API at binary level and possibility to use softIP in one system with Dialogic(R) Diva(R) ISDN (E.1/T.1/S0) and POTS hardware ensures high level of compatibility to existing applications and environments and allows step by step migration from ISDN/POTS to IP.

SoftIP allows to use following Dialogic(R) Diva(R) ISDN/Analog hardware for media processing:

• Diva 4PRI PCI, Diva 2PRI PCI, Diva 4PRI PCIe HS, Diva 2PRI PCIe HS, Diva 1PRI PCIe

• Diva PRI v.3

• Diva 4PRI Rev.2 PCI, Diva 4BRI PCIe, Diva BRI Rev.2 PCI, Diva BRI PCIe

• Diva Analog PCI and PCIe

This allows to preserve hardware by migration to IP.

The mapping between SIP urls and ISDN numbers is held in one text file (CVS format) which can be created and changed by customer own tools if necessary.

Example Diva 4BRI -8M Rev.2

Using Diva 4BRI Rev.2 this is possible to use one or more interfaces (or all of interfaces) in resource board mode and allow use of DSP resources (two for every interface) by softIP. For example:
