[SR-Users] how to get a value from SIP INVITE Header

[Henning Westerholt]

Hello,

can you share the error you have got? If you just want to get the substring of the +34xxxxx at domain URI, have a look to the string transformations on the same link.

Cheers,

Henning

Hi.
Thanks for your response. I went through the uri transformation page, tried it but no luck.

Is there any other method to slice the string from +34xxxxxxxxx at sub.domain.com<mailto:+34xxxxxxxxx at sub.domain.com> to +34??

Hello,



have a look to the transformations for URIs: https://www.kamailio.org/wiki/cookbooks/devel/transformations#uri_transformations

There is one to get parameters as well.



$shm variables are shared in shared memory, so you can share them in other calls. The $avp/$xavp are shared between processes, but belongs to the SIP transaction.



About routing calls by prefix – have a look to the lcr, carrierroute or drouting modules, for example.



Cheers,



Henning

Hii



Please help me to get the a value from SIP INVITE header reached to kamailio like INVITE sip:+341930203454 at sub.domain.com<mailto:341930203454 at sub.domain.com>;myid=+34 at sub.domain.com<mailto:34 at sub.domain.com> SIP/2.0 and i want to save the myid value +34 into a variable, without the domain name.





     $var(uri) = $sel(ruri);

     xavp_params_explode("$(var(uri){s.unbracket})", "uri");

     xlog("L_INFO", "$var(uri) Received converted to $xavp(uri=>myid[0])\n");



I tried above and it prints +34 at sub.domain.com<mailto:34 at sub.domain.com> But i want to just save +34 into a variable to further check the prefix based routing from the database.



1) Could you please help how to get it or If there is any alternate/single line approach to get this value?

2) $var & $xavp are process-local variables, and they cant be shared with other calls? Right

3) What is the best module to route calls based their prefix ? pstn_route or dynamic routing or any suggestions?



Please help, thanks in advance.
