ASN.1 compilers; request

While at the IMTC meeting in Munich yesterday, a question was raised by an implementor who was having trouble compiling the ASN for H.323 V2. I suggested using the OSS or Teles ASN.l compilers, both of which he had not yet tried.

However, this raises some interesting questions:

1)What is the complete list of available ASN.1 compilers, both commercial and free?

2)Are there known problems with some products that implementors should be warned about?

I have in mind a section in the implementors guide on this topic. Please post responses to this request to the list so that all can benefit ASAP. I will as the editor of the implementor's guide to collect and edit the results for the guide.

Thanks for your attention,

Dale Skran Q13 Rapporteur
