[asterisk-users] Properly Escaping Quotes and Commas

[Danny Nicholas]

You could use the REPLACE function to zap the quotes and commas.

asterisk -rx "core show function REPLACE"

 

  -= Info about function 'REPLACE' =-

Replace a set of characters in a given string with another character.

ar>.  <replace-char> may be either empty or contain one character.  If
empty,

all <find-chars> will be deleted from the output.

not altered.

Subject: [asterisk-users] Properly Escaping Quotes and Commas

 

Hello all,

I have a setup where Asterisk sends a message to a few jabber users on each
incoming call, like:

 

exten => s,n,Macro(sendim,"Incoming call from ${CALLERID(all)}")

 

The macro looks like this:

 

[macro-sendimuser2]

exten => s,n,JabberSend(asterisk,user2 at gmail.com,${ARG1})

exten => s,n,JabberSend(asterisk,user2 at internal.jabber.server.tld,${ARG1})

 

[macro-sendim]

exten => s,1,Noop("Holder");

same  => n,Macro(sendimuser1,${ARG1})

same  => n,Macro(sendimuser2,${ARG1})

 

The issue I'm having, is if the callerID contains a command, such as:
Lastname, Firstname, ${CALLERID(all)} turns into "Lastname, Firstname"
<number>.

 

This seems to mess up the quoting, as the macro argument expands to be

"Incoming call from "Lastname, Firstname" <number>, and the ${ARG1} as the
macro sees it is set to "Incoming call from "Lastname

 

The comma ends up outside the double quotes and then it splits the macro
arguments.

 

What's the best way to do this right?

 

 

Thanks!!!
