Patching asterisk

[Florian Hackenberger]

Hi!

For a project I'd like to patch asterisk and rebuild the debian package. 
I'm quite new to maintaining debian packages and the standard approach 
of:
$ apt-get source asterisk
$ cd asterisk-1.4.X
modify files
$ debuild -S -sa -us -uc
$ cd ..
$ sudo pbuilder --build asterisk-1.4.X.dsc

does not work because the patches in debian/patches/ do not apply 
cleanly after modifying the source code.
	Could someone please give me a few hints about how to apply a 
modification and rebuild the package? Another question would be the 
proposed workflow for a edit/build/execute/edit cycle. How do I avoid a 
complete rebuild, but still build with debian ./configure parameters 
etc. ?

Thanks in advance!

Cheers,
	Florian
