can I parse a voip call (h323 family, SIP, IAX etc.) Is wireshark
capable of doing it.
Yes.
Can somebody send me a source code for parsing voip call in C
language.

Even if you strip out everything except the link-layer, IP, TCP, and
SCTP dissectors, and the protocols running atop them in VoIP calls,
and all the facilities in the Wireshark core that aren't needed to
support those dissectors, that's a *lot* of code. Dissecting packets
isn't something you can do with a quick little bit of C code.
Now, if by "parsing" you meant "constructing and sending, and
receiving and processing" - i.e., you want to implement VoIP - there
are other free-software projects for that (Asterix, for example).
However, for those, see the previous paragraph; that's still a *lot*
of code.
