Video Codec Plugin Problem Continued
by Abhishek Rohilla 09 Jan '08

09 Jan '08

Hi I have done as you mentioned in class derived from H323EndPoint. I added capabilities as follows. AddAllCapabilities(0, 0, "*"); AddAllUserInputCapabilities(0, P_MAX_INDEX); I am using Visual Studio.Net 2003 for my application. This is the trace in the output window of VS 2003 Loaded 'C:\PWLIB_PLUGINS\h261vic_pwplugin.dll', No symbols loaded. Loaded 'C:\PWLIB_PLUGINS\h263ffmpeg_pwplugin.dll', Symbols loaded. I guess the dlls are loaded but codecs are not actually plugged in because of some reason. When I checked the capabilities only two codecs G711 U and A law are there in it and remaining 8 enteries show H323_UserInputCapability string . Please Help!!!

h323plus Makefile fails to install all headers
by Adam Williamson 26 Dec '07

26 Dec '07

Trying to build anything against h323plus, it quickly becomes obvious that there's a bug in the Makefile. It only installs include/*.h - not include/<subdirs>/*.h . So nothing will build, because h323.h references other headers from the subdirectories, which are not installed. This patch to Makefile.in makes it install the stuff from the subdirectories, resolving that problem. -- adamw

General WorkPlan for H323plus
by Simon Horne 25 Dec '07

25 Dec '07

Guys As you are aware the focus of H323plus is about the plus (new features/services) and less about architecture redesign allowing existing applications to be upgraded/improved without requiring wholesale code changes yet still have access to the latest and greatest features like H.239, H.350 etc. With the exception of the upcoming upgrade to PTLib 2.x we hope to continue in that vain. As most of you are aware I also have commitments to GnuGk and PacPhone so I am spread thin at the best of times but at the moment it is quite accute. I have 5 documents to be presented to the ITU meeting in Korea in January as well as other work which I hope to make an announcement on in the new year. Here are some the current work items. Migration to ptlib 2.x (ETA January) which has been previously discussed. Addition of GnuGK NAT Traversal. (ETA 1 week) This will allow the H323plus based applications to natively traverse NATs using GnuGk. The code has been tried and tested and working with PacPhone for over a year, I have just tidy up it and added better documentation. Note this is not the ITU standard method which is H.460.18/19. H.235.6. (ETA January) This is the defacto standard for H.323 Media encryption with support with polycom PVX, Tandberg and Codian. Thanks heaps to bian xuegong for helping sort it out. There is some new work at the ITU upgrading the encryption from AES128 to AES256 so hopefully that will be included. File Transfer. (ETA January) This is really cool. This allows the transfer of files via TFTP encaptulated in RTP frames allowing lightweight data transfer without the need for the T.120 framework overhead. Since it uses RTP it can use existing NAT Traversal mechanisms like GnuGk to traverse NATs. I am putting forward a submission to the ITU on this so watch out for that. H.460.presence (ETA Feburary) I have a submission to the ITU for scalable presence system I have been working on for sometime. I hope to have this finalised and committed by Feb. H.460.MMS (ETA ?) Multimedia Messaging. This is also up for submission to the ITU. This is a companion and extension on H.460.tm (Text Messaging) which is in the extensions directory of the CVS. There is an exciting year ahead for h323plus. Simon

H323plus and ptlib 2.x?
by Adam Williamson 25 Dec '07

25 Dec '07

So, second question :) I've now got h323plus built and in the distro. But it doesn't build against ptlib 2.x, only ptlib / pwlib 1.12. This means I have a fairly ugly mess of packages in Mandriva right now - separate packages for ptlib 2.x and pwlib 1.12 which conflict in lots of fun ways. I need both as current Opal wants ptlib 2.x, but h323plus wants pwlib / ptlib 1.12... I guess h323plus will be migrated to build okay against ptlib 2.x, right? Is there an ETA on this? Thanks! -- adamw

t38modem connecting to innovaphone IP400
by Marcus Robichon 20 Dec '07

20 Dec '07

Hi all, hope this list he correct list to ask fort he t38modem. We need the following due to virtualization of hardware: We use Hylafax as Fax solution. We try to implement t38modem to talk via H323 (T38) protocol to a innovaphone IP400 router. First we implemented the OpenH323 solution. We can connect to the innovaphone router and we can see that the router is calling. But after some seconds we get a I/O error back. Then we tried to upgrade the whole project to h323plus and the new release of t38modem (0.8.4). We tried the same but we get the same error message. Did anybody have a solution for this? Attached you get a logfile to see some "blabla" of t38modem. I cannot come along why this does not work. This is the string we are using to connect to the gatekeeper on innovaphone: t38modem -p ttyp0 -tttttt -g 172.16.25.19 -u HYLA -i 172.16.25.134 --redundancy H -P T.38-UDP --h245tunneldisable Have a nice day.

Video Codec Plugin Tutorial
by Abhishek Rohilla 19 Dec '07

19 Dec '07

H323Plus has now supported all the video codec as plugins. Can someone help me as to how to plug in video codecs into H323Plus. Earlier for H.263 we had to just add the capabilities as the codec class was there in the code. But now that thing does not work with H323Plus.

回复： H.235 AES problem continue
by Bian 11 Dec '07

11 Dec '07

Simon, The diffie-hellman is used to exchange shared secret which is then used to encrypt sessionKey. The sessionKey is used to encrypt media then. The secret shared (the key) I have got from standard key exchange procedure is equal to "H.235 encryption check code" displayed by PVX UI. It's difficult to think polycom using private mechanism. That means polycom cannot interoperate with other endpoints in standard way. The sharedSecret field within the H235Key structure uses the following fields: • algorithmOID: set to "X", "X1" for the 56-bit RC2-compatible, set to "Y", "Y1" for 56-bit DES or set to "Z", "Z1" for 168-bit Triple-DES or set to "Z3" for 128-bit AES. NOTE 1 – The session key encryption algorithm is the same as the negotiated media encryption algorithm. ( here is the answer? ) Each entity shall take appropriate least significant bits from the common shared Diffie-Hellman secret for the key encryption key (master key); i.e., the 56 least significant bits of the Diffie-Hellman secret for OID "X", OID "X1", OID "Y1" or OID "Y" and the 168 least significant bits of the Diffie-Hellman secret for OID "Z", OID "Z1" or OID "Z2" and the 128 least significant bits of the Diffie-Hellman secret for OID "Z3" or OID "Z2", see also Table 6. ( here is the answer? ) bian ----- 原始邮件 ---- 发件人： Simon Horne <s.horne(a)packetizer.com> 收件人： Bian <bianxg(a)yahoo.cn>; H323plus <h323plus(a)lists.packetizer.com> 已发送： 2007/12/11(周二), 下午8:58:15 主题： RE: [h323plus] H.235 AES problem continue Bian Polycom is not using H.235.6 key exchange and most certainly not using diffie-hellman. It is using symmetric key AES encryption which is AFAIK is NOT standard. The key material is encrypted using a private mechanism. Let me explain what this is > algorithmOID = 2.16.840.1.101.3.4.1.2 > // <"OID_Z3" which means using AES 128 CBC mode > paramS = { > // means IV is 0 > } > encryptedSessionKey = 16 octets { > c7 36 02 5c b7 ae b0 cc 97 c8 af bb d5 72 0f 19 AlgorithmOID has nothing to do with the encryptedSessionKey. The AlgorithmOID notifies the remote what cipher to use DES 3DES or AES. This is standard identifier. Basically this tells the remote to use AES. encryptionSessionKey is encrypted using an non-public known secret method. The only way you are going to decrypt this is if you know how the key is encrypted. AFAIK only polycom can provide you that information. It is not public knowledge.

H.235 AES problem continue
by Bian 11 Dec '07

11 Dec '07

Hi I have finished call procedure of H.235 and get same H.235 encryption check code with PVX. (See attach) This is the shared secret(PVX only display 8 bytes long, whereas the h.235.6 indicate 16 bytes long see below). As slave, local endpoint receive OpenLogicalChannel rerquest, which has a parameter H235_V3KeySyncMaterial. The param content is as below: { algorithmOID = 2.16.840.1.101.3.4.1.2 // <"OID_Z3" which means using AES 128 CBC mode paramS = { // means IV is 0 } encryptedSessionKey = 16 octets { c7 36 02 5c b7 ae b0 cc 97 c8 af bb d5 72 0f 19 .6.\.........r.. } } Then local endpoint begin to decrypt sessionKey from encryptedSessionKey using shared secret. But decryption is failed. Can anyone help to analyse where is the wrong. The below is piece of code decrypting sessionKey (using openssl-0.9.8g) ret = EVP_DecryptInit(&ctx, EVP_aes_128_cbc(), NULL, NULL); PAssert(ret, PLogicError); ret = EVP_CIPHER_CTX_set_key_length(&ctx, 16); PAssert(ret, PLogicError); ret = EVP_DecryptInit(&ctx, EVP_aes_128_cbc(), key, NULL); // IV is null here . key is same as PVX's H.235 encryption check code (PVX only display 8 bytes) PAssert(ret, PLogicError); ret = EVP_DecryptUpdate(&ctx, buffer, &outl, (unsigned char *)in.GetPointer(), 16);// but the "outl" returned is 0 which shall be 16 here I think. len += outl; ret = EVP_DecryptFinal(&ctx, buffer+len, &outl); // return 0 here, means error is found (Each entity shall take appropriate least significant bits from the common shared Diffie-Hellman secret for the key encryption key (master key); i.e., the 56 least significant bits of the Diffie-Hellman secret for OID "X", OID "X1", OID "Y1" or OID "Y" and the 168 least significant bits of the Diffie-Hellman secret for OID "Z", OID "Z1" or OID "Z2" and the 128 least significant bits of the Diffie-Hellman secret for OID "Z3" or OID "Z2", see also Table 6.)
