[SR-Users] Problem with URI transformations

[Julien Klingenmeyer]

Daniel,

I just did some tests the same way as Duarte’s and the parameter I think you mentioned ({uri.uparam}: “Return the value of user parameter”) does not work as expected:

URI sip:123456789;test=param;phone-context=abcd at 1.1.1.1;user=phone
$(var(URI){uri. uparam}) = "phone"

URI sip:123456789;test=param;phone-context=abcd at 1.1.1.1
$(var(URI){uri. uparam}) = ""

Am I missing something?

Objet : Re: [SR-Users] Problem with URI transformations

As far as i know, the URI transformations only provide the "user" parameter, not the user part parameters.

What i'm trying to do i build an object for Diversion and Contact. To do that i'm trying to parse the header and URI into it's elements.

URI Example : <sip:123456;parameter=hello;parameter2=hey at 1.1.1.1<mailto:hey at 1.1.1.1>;kamailio=test>

Elements :
  User : 123456
  User Parameters : parameter=hello;parameter2=hey
  Domain : 1.1.1.1
  URI Parameters = kamailio=teste
To achieve this i'm using uri.user , uri.domain , uri.port and uri.params.

uri.user will normally return "123456;parameter=hello;parameter2=hey" and after that i mannually split the user and teh user params. However, in the event of a TEL_URI with user=phone on uri.params, "parameter=hello;parameter2=hey" won't be present in the uri.user.

It seems like i should be doing a special case for when user=phone is present. What do you think ?

Hello,

check the URI transformation docs, iirc there is an option to get user parameters.

If not, can you give an example of what params you want to work with, likely you can get it with other transformations...

Cheers,

Greetings,

My issue was related to user part parameters being lost. I didn't know that the parse would work differently when user=phone was present. Thank you for pointing that out.

That being said, how should i proceed if i want to check user part parameters in this scenario? Like phone-context for example.

Best Regards

Hello,

what did you expect to be? To be able to comment on the exact topic.

user=phone changes the structure of the URI in something similar to tel URI.

Greetings,

I'm trying to parse some URI info on Kamailio but i'm having some troubles the URI transformations.

Here i have two examples of URIS from which i'm trying to extract username(with user parameters included) and URI Parameters :
- sip:123456789;test=param at 1.1.1.1<mailto:param at 1.1.1.1>
- sip:123456789;test=param at 1.1.1.1<mailto:param at 1.1.1.1>;user=phone
In order to test this i made the following code :

$var(URI) = "sip:123456789;test=param at 1.1.1.1<mailto:param at 1.1.1.1>";
xerr("DEBUG 1 : URI $var(URI)");
$var(User) = $(var(URI){uri.user});
$var(Parameters) = $(var(URI){uri.params});
xerr("DEBUG 1 : User = $var(User)");
xerr("DEBUG 1 : Parameters = $var(Parameters)");
$var(URI) = "sip:123456789;test=param at 1.1.1.1<mailto:param at 1.1.1.1>;user=phone";
xerr("DEBUG 2 : URI $var(URI)"); ;
$var(User) = $(var(URI){uri.user});
$var(Parameters) = $(var(URI){uri.params});
xerr("DEBUG 2 : User =  $var(User)");
xerr("DEBUG 2 : Parameters = $var(Parameters)");
The result is the following :
DEBUG 1 : URI sip:123456789;test=param at 1.1.1.1<mailto:param at 1.1.1.1>
DEBUG 1 : User = 123456789;test=param
DEBUG 1 : Parameters =

DEBUG 2 : URI sip:123456789;test=param at 1.1.1.1<mailto:param at 1.1.1.1>;user=phone
DEBUG 2 : User =  123456789
DEBUG 2 : Parameters = user=phone
If the URI has parameters, the User parameters won't be included in the User part.

Is this a bug or is it working as intended? I'm running Kamailio 5.2.0 .

Thank you for your time.

Best Regards,

Duarte Rocha
