Hi,
I also have the same question, why don't you use the existing VoIP analizer?

Hi,
I'm not sure what you need but packet-per.c is used to decode the PER encoded stuff but it may not suit your needs.
Another option is to look at openh323.
But isn't building another VoIP analyser reinventing the wheel? Why not work on the VoIP analysis code of Wireshark?

Hi people.
I'm developing a VoIP protocol analyzer for a University educative module, for learning VoIP signalling protocols. I'm working with SIP and H.323. The SIP part is ready, and the Q.931 part of H.323 is also ready. But now I'm having issues with the ASN.1 enconding of H.225.0 and H.245. I know that first I need to compile the ASN.1 tree to the language of my preference (C in this case), and it is already done. But besides the structures generated by the compiler, now I need to develop the decoding routines, which have to work with the PER alligned rules.
I wanted to know how Wireshark does to decode it?
Thanks in advance.
