Again please check you paths. H224 is a newer feature added to H323Plus and you should have no problems compiling it. You may want to disable it entirely at compile time by --disable-h224 but I think it is a path issue pointing to an older openH323 release.

Hello Simon,

After I compiled h323plus successfully I tried to have Asterisk's chan_h323 built with h323plus.

I made the necessary changes in Asterisk's ./configure script in order to reflect the library changes (mostly path changes).

The only problem that remains now is that the verification of the H323plus installation fails, because the configuration script cannot compile a small test program.

Here is the log from the configure:

***************************** checking OpenH323 installation validity configure:26734: g++ -o conftest -g -O2 -I/Downloads/h323+/h323plus/include -I/Downloads/h323+/ptlib_v1_12_0/include conftest.cpp -L/Downloads/h323+/h323plus/lib -lh323_linux_x86_r -L/Downloads/h323+/ptlib_v1_12_0/lib -lpt_linux_x86_r >&5 /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `OpalH224Handler::SendExtraCapabilitiesMessage(unsigned char, unsigned char*, int)' /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `OpalH224Handler::TransmitClientFrame(unsigned char, H224_Frame&)' /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `H224_Frame::H224_Frame(int)' /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `H224_Frame::SetES(int)' /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `H224_Frame::SetHighPriority(int)' /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `typeinfo for H224_Frame' /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `H224_Frame::~H224_Frame()' /Downloads/h323+/h323plus/lib/libh323_linux_x86_r.so: undefined reference to `H224_Frame::SetBS(int)' collect2: ld returned 1 exit status *****************************

The conftest.cpp is below: ***************************** #include "ptlib.h" #include "h323.h" #include "h323ep.h"

int main () { H323EndPoint ep = H323EndPoint(); ; return 0; } *****************************

Do you have any quick recommendations that I can try before I try to go through the H323plus library's code later tonight?

Best regards, Vlasis.

Yes. There are two defines in the openh323buildopts.h to enable

aggregation

H323_SIGNAL_AGGREGATE H323_RTP_AGGREGATE

By default they are undefined.

H323plus is designed as a Linux drop in replacement to OpenH323 with of course a lot more features.

The purpose of the project is to do just what you are intending, to update existing projects which are based on OpenH323 and add more H323 support to those projects.

If you need assistance then let me know. It would be good to have asterisk chan_h323 updated to h323plus.

Hello,

A couple of years ago the following paper was written by Craig Southeren about increasing the call capacity of OpenH323 & OPAL:

http://www.voxgratia.org/docs/call%20thread%20handling%20model%201.0.pdf

We could see in the release milestones of OpenH323 at:

http://www.voxgratia.org/docs/milestones.html#milestones

that signaling and RTP aggregation was intended for OpenH323 v1.19.0 (Titan).

I'm sorry if this question has been answered before or if the answer if obvious, but I wanted to know if these enhancements are there in the current release candidate of H323plus.

I tried to look through relevant mailing lists (even the older Openh323 mailing lists) but I couldn't find any useful information.

If this is the case I intend to use H323plus to replace the older OpenH323 libraries in a couple of open source projects, like Asterisk etc.
