[asterisk-users] Problem with MFCR2

Carlos. Unblocking the remote side is NOT your responsibility, unless
you own the 2 end points :). I suppose you are getting connected to
some telco (avantel, telmex, etc), if so, is telco's responsibility to
unlock their side.

To discard any problem with Asterisk, try using "testcall" utility
included with libunicall. testcall will allow you to debug the problem
without using Asterisk at all.

Here is a link on my blog for a document I wrote that may help you out.

( is in spanish, since most people using MFCR are either on Brazil or Mexico )

http://phpmexic.u33.0web-hosting.com/wordpress/misc/mfcr2-asterisk-unicall.pdf

It describes some debugging techniques.

Best Regards
