Summary:                    Problems with Escaping Characters on SIP Calls in
Dial() and Transfer() Applications
Description: 
There is an inability to escape characters and send certain characters in
Dial() and Transfer().

Specifically:

(1) Using Transfer(), Semicolons cannot be sent without using a backslash
to escape them. If you send the semicolon without a preceding backslash,
the Transfer() application ignores anything to the right of the semicolon
as if you are desiginating a comment to be ignored in execution.  

The problem is that when using a backslash to send a semicolon or other 
character, the Transfer() application embeds the backslash in the SIP
dialog.  

(2) In both the Dial() and Transfer() applications, you can no longer
embed a % to create an escaped character in the SIP dialog.  (This seemed
to work in Asterisk 1.6)  Asterisk converts the % to %25 in the SIP dialog.
 So, there is no way to escape other characters in a SIP dialog.  My tests
show that ncluding a preceding backslash does not prevent the conversion of
the % to %25 in the SIP dialog.
