H323SIP果然难于共存。Openh323原有的开发者也将分为两大块:

OPAL VOIP: 保留Opal现有H323功能,但重点明显是要向兼容SIP方向发展;其网站介绍为:

OPAL implements the commonly used protocols used to send voice, video and fax data over IP networks. Originally part of the OpenH323 project, OpalVoip has grown to include SIP and IAX2.

h323plus:在原有OpenH323基础上继续完善ITUH323系列的协议,其介绍为:

            The H.323 Plus project intends to do much more than simply provide a new home for open source H.323 developers. Developers have told us they intend to work to provide significant new enhancements to the very successful H.323 systems deployed worldwide. For example, NAT/FW traversal, instant messaging, presence, and many other enhancements are already in progress or being planned. Further, the open source community has expressed interest to us to enable more collaborative features to H.323, including such things as application sharing, whiteboarding, and other capabilities.(可惜,这些功能OPAL将不能用到了)

 

至于底层的pwlib(即ptlib)估计暂时还会保持一致。



分家后期邮件列表也将分开:

对于我们可能会更关心OpenH323的主要开发者 Simon 的以下言论:  

The following projects are currently planned to be supported within H323plus.

OpenMCU (including remote conference controls) OpenAM  (upgraded to support VoiceMail support to GnuGk) MyPhone OhPhone

 

The Library is almost drop-in replacable with the existing OpenH323 and contains numerous enhancements including video plugins (compatible with

Opal) and large amount of new work not currently supported in Opal.

 

Some of the new work now available in h323plus H.230  Conference Controls (incl tunneling GCC (T.124))

H.239  Application Sharing

H.249  Extended user inputs

H.341  SNMP support

H.350  LDAP WhitePages

H.460  Numerous custom Extensibility features

        Text Messaging (working doc ITU),

        Follow Me,

        PDI (Personal Data Interchange)

H.460.9 RealTime QoS Measurements

Video Plugins (fully compatible with Opal)

H.235 Plugins (for external Biometric and smartcard authenticators) QoS Capability negotiation Conference Controls capability advertisement.

 

New work planned/proposed

H.460.presence

H.460.18/19 Nat Traversal

Video on Demand project (using H.239/H.249)

 

We can also provide full consulting service support for existing openH323 based projects as well as provide assistance in migration of these projects to h323plus.
