asterisk users - Oct 2010 - Checking SIP Headers existence and content

Hello,

I would like to verify if a specific SIP header exists, and if yes, extract
the partial content from another header.

1. Is there a way to verify if a specific header exists?
2. How do I extract data that is between the first : and the following @?
Specifically, The data looks like <sip:1234567890 at 10.0.0.1:5060> and I
would
like to get only the 1234567890

I tried to use the CUT() command, but without success.

Thank you.

Michael

Something like

exten => s,1,Set(__DIALEDNUMBER=${SIP_HEADER(TO):5})
exten => s,n,Set(__DIALEDNUMBER=${CUT(DIALEDNUMBER,@,1)})
exten => s,n,GotoIf($["${DIALEDNUMBER:0:1}" !=
"+"]?numberIsOK)
exten => s,n,Set(__DIALEDNUMBER=${CUT(DIALEDNUMBER,+,2)})
