Hi Simon,
I work with Claudio and we are having problems with the CVS version. Inbound calls are not working.
The first problem is regarding the creation of the H245 channel then I saw the following change in file transports.cxx:
H323Transport * H323TransportTCP::CreateControlChannel(H323Connection & connection) { H323TransportTCP * tcpTransport = new H323TransportTCP(endpoint, localAddress, /*there was a TRUE here */);
Why this was changed?
When I put the TRUE back the execution proceeded but then failed in another point. Then I saw that it seems one of the TLS related variables is set even though I was not using TLS. I think the problem is in the same file at:
PBoolean H323TransportTCP::SecureAccept() { #ifdef H323_TLS #if PTLIB_VER < 2120 ssl_st * m_ssl = ssl; #endif if (m_ssl)
It seems the variable m_ssl is set so the SecureAccept function ends up returning false thus terminating the call. I could not find where this variable is set and we had to disable TLS to make inbound calls work again. I think the issue is reproducible with the simple example. I appreciate any help. Thanks.

Update: H323_ExternalRTPChannel with encryption support has been added to the
CVS.
There is a new wrapper channel for H323_ExternalRTPChannel called H323SecureChannel which handles all the key exchange and media encryption/decryption if required.

Yes the current H.235 Implementation does not take into account the use
of
external RTP channel. I will put that on my TODO list to fix before the
next
release.

Jan,
Thank you.
I had some progress towards establishing a H.235 call but it is falling
when
it tries to open the logical channel. So my question is: Is it possible to use H.235 along with external
channels?
I'm asking this because H323RealTimeCapability::CreateChannel calls connection.CreateRealTimeLogicalChannel (where you can provide your own external channel subclass) but
H323SecureRealTimeCapability::CreateChannel
creates a new H323SecureRTPChannel (it does not call any function where
you
could return your own subclass). When I don't use H.235 I get the
following
log:

Hi Claudio,
take a look at the provided sample application "Simple". When you start it with command line argument "-m 128", it will do H.235
AES
128 media encryption.

Hi,
We are developing an H.323 EP and we need to use the H.235. Is there any example using this? We are using h323plus V1.24.0 and we enabled the H.235.
Thanks
Claudio
