asterisk users - Jul 2012 - Finding the position of a character in a string

It there a native asterisk dialplan function which will tell me the
position of a specific character in a given string?

eg if I wanted to find what position the '@' was at in ${SIPURI}

Thanks in advance

if you are trying to extract parts from a string then look at the 
function called 'CUT'.

verbose example:
exten => s,1,NoOp(set DID from SIP TO header)
exten => s,n,Set(DID_INFO=${SIP_HEADER(To)})
exten => s,n,Set(DID_INFO=${CUT(DID_INFO,@,1)})
exten => s,n,Set(DID_INFO=${CUT(DID_INFO,:,2)})
exten => s,n,Goto(sip-routing,${DID_INFO},1)

Worst case scenario: write a loop to iterate over each character and 
stop at first match.

If you have ODBC installed: your SQL back-end should be able to perform 
this function for you.

See if the dialplan function FIELDNUM can be used.

There must be many more ways.
