[asterisk-users] Error in intalling library for r2mfc support to asterisk

[sanchal.singh at alliance-infotech.com]

Hi,
    I am trying out with the steps given in the link
<http://moy.ivsol.net/unicall/soft-switch/> I got all the libraries spandsp,
libmfcr2, libsupertone, libunicall
Now, the problem is libmfcr2 is asking for libunicall library and libunicall
library is asking for lots of symbol not found while linking.
              I am using (1)	asterisk-1.2.19.tar.gz
			libmfcr2-0.0.3-1.4.tar.bz2
			libsupertone-0.0.2.tar.gz
			libunicall-0.0.3-1.4.tar.bz2
			spandsp-20060903.tar.gz

	Can anybody tell me that problem is due to any version mismatch between
asterisk and mfc/r2 library.
Thanks and regards
