Reply To: SIP .v. H.323

Tom Howard

Hi Romel,

Long time – no hear!

As a software developer, I certainly prefer SIP. I am writing an H.225 protocol stack at the moment. It’s going very well. But, before I could start, I needed to understand ASN.1 and PER X.691 [why PER, just to save a few bits here and there 🙁 ]. It has taken weeks to get my head round them. Although they are impecible in their logic, I don’t believe they were written by people who will actually use and implement them. IETF recommendations are far easier to implement.


p.s. Looking forward to seeing the book. Is it out yet?
