Summary:                    DTMF tones not recognized with Exchange 2010 Unified
Messaging
Description: 
Asterisk 1.8.1.1 (PBX in a Flash) running on CentOS release 5.5 does not
correctly send DTMF to Exchange 2010. This is the same problem as reported
in https://issues.asterisk.org/view.php?id=18352 except that it still
appears in version 1.8.1.1 as well. The proposed fix for the referenced
issue does not correct the problem in this case:

Changing lines...

from:
ast_indicate(c0, AST_CONTROL_SRCCHANGE);
ast_indicate(c1, AST_CONTROL_SRCCHANGE);
to:
ast_indicate(c0, AST_CONTROL_SRCUPDATE);
ast_indicate(c1, AST_CONTROL_SRCUPDATE);

...does not help.
