------------------------------------------
Description:
*+Synopsis+*:
SIP Client <-> Asterisk/ooh323 <-> GnuGk <-> H323 Client (ITU version > 2005).
Remark : H323 client configuration is not modifiable for "transportCapability" parameters; this client is based on a previous H323 ITU standard of 2005
*+Steps+* :
- H.323 client send the following H323 message to Gnugk, then ooh323 :

{code}

The {{ooh323}} add-on could not decode the QoS parameters « LocalQoS » and « dscpValue » received from the H323 client (cf. Asn.1 decoding errors).
The SIP part of Asterix is still usable but the h323 add-on is not more responsive as soon as the first « OpenLogicalChannel » with QoS « LocalQoS » et « dscpValue » parameters is received.
*+Analysis+*:
The {{ooh323}} add-on is based on a Asn.1 structure that does not include these 2 QoS parameters (cf file MULTIMEDIA-SYSTEM-CONTROL.h )
*+Correction proposition+*:
- still decode messages from H323 clients in accordance with ITU standard until 2005
- do not try to decode QoS unknown parameters for H323 clients with ITU standard post 2005
