[h323plus] Avaya Authentication methods

Hi,

I was just discussing with Simon if anybody would need the Avaya authentication procedures OID 1.3.14.3.2.6 and OID 2.16.840.1.114187.1.3 in H323Plus.

Both are said to be DES based, so they don't offer much security, but they can be useful with legacy equipment.

I have an almost complete implementation for OID 1.3.14.3.2.6 in GnuGk, that just needs a little fleshing out for the encryption part which GnuGk doesn't need, before it can be moved into H323Plus.

For OID 2.16.840.1.114187.1.3 I have some stub code that allows endpoints to register with GnuGk, but some crypto details are still uncertain.

So, if anybody needs this stuff, please speak up. ;-)

Cheers, Jan
