Hi!

[I first would like to appologize if this is the wrong forum to direct our ITU-standard question in, please inform me if it is inproper]

The question concern implementation of Call Forwarding, i.e. ITU-std H450.1 and H450-2.

We are planning to implement Call Forwarding support into a telephonysystem using IP-telephony based support(i.e. H323 and similar). The standard for Call Forwarding is described/defined in H450.1 and H450-2 (and others).

The problem is that we need to parse the ASN syntax into true implementation files (.h/.c/.cpp) but we have failed in finding a ASN parser that supports the specific syntax in H450.1 and H450-2.

Is there a ASN parser that can "compile" the H450.1 and H450-2 (and preferable higher H450:s) standard protocols?

Are there any "true" alternatives (beside using H450.2 and H450-2) when implementing Call Forwarding?

Are there any other developers that has implemented Call Forwarding that would like to share their experiences with us?

Thanks in advance!
