Hello,

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

Example: P-Asserted-Identity: "Cullen Jennings" sip:fluffy@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.

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?

Hello,

this should work unless there are parameters with the same name in userpart, or uri part or header body part.

Perhaps the safest mode is to apply first the tobody transformation to extract the part you want then apply the params transformation.

Cheers, Daniel

Hi Daniel,

Yes, you are absolutely right! Thank you for pointing that out!

Is it possible to use regex inside the cfg script and use groups to extract the value?

Quick regex example (needs tweaking): tel:(+\d{1,20})tel:(\+\d%7b1,20%7d) and then use a pseudo-variable to get the first group? https://regex101.com/r/dN7bY8/1

P-Asserted-Identity: "Cullen Jennings" sip:fluffy@cisco.com P-Asserted-Identity: tel:+14085264000

Hello,

there is a transformation for regexp substitutions, see the transformations cookbook on kamailio.org/wiki.

Also, if you just want everything after 'tel:', then you can use string transformations like substring or select.

Hi Daniel,

I used the regexp sub, and it works!

If anyone is interested, here is the code:

$var(p_asserted_identity) = $(hdr(P-Asserted-Identity)[*]); xlog("L_INFO", "P-Asserted-Identity: $var(p_asserted_identity) \r\n"); $var(caller_id) = $(var(p_asserted_identity){re.subst,/.*tel:(+?[[:digit:]]+).*/\1/}); xlog("L_INFO", "Retrieved CallerId ($var(caller_id)) from P-Asserted-Identity header \r\n");

Debug log: P-Asserted-Identity: "Grant" sip:grant@domain.com,tel:+3101234567 Retrieved CallerId (+3101234567) from P-Asserted-Identity header

Grant

Yes, you are absolutely right! Thank you for pointing that out!

Is it possible to use regex inside the cfg script and use groups to extract the value?

Quick regex example (needs tweaking): tel:(+\d{1,20}) tel:%28%5C+%5Cd%7b1,20%7d%29 and then use a pseudo-variable to get the first group? https://regex101.com/r/dN7bY8/1 https://regex101.com/r/dN7bY8/1

P-Asserted-Identity: "Cullen Jennings" sip:fluffy@cisco.com sip:fluffy@cisco.com P-Asserted-Identity: tel:+14085264000 tel:+14085264000

Hello,

this should work unless there are parameters with the same name in userpart, or uri part or header body part.

Perhaps the safest mode is to apply first the tobody transformation to extract the part you want then apply the params transformation.

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

Hello,

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

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