[SR-Users] Extracting P-Asserted-Identity value

[Grant Bagdasarian]

To answer my own question.
This does parse:

                                               $var(p_asserted_identity) = $(hdr(P-Asserted-Identity)[*]);
                                               $var(caller_id) = $(var(p_asserted_identity){param.value,'tel',:});

But, I'm not sure if this is the correct way to do this. Maybe someone else has a more elegant solution?

Subject: [SR-Users] Extracting P-Asserted-Identity value

Hello,

How do I extract the value of "tel" from multiple P-Asserted-Identity headers?

Example:
   P-Asserted-Identity: "Cullen Jennings" <sip:fluffy at cisco.com>
   P-Asserted-Identity: tel:+14085264000

What I got so far is:
                                               $var(p_asserted_identity) = $(hdr(P-Asserted-Identity)[*]);
                                               $var(caller_id) = $var(p_asserted_identity){param.value,'tel',':'};

But this does not work. I keep getting parser errors when doing the transformation (2nd line of code example):
I'm not sure how to format the line of code. I tried multiple ways, but none work.
