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

[sai sudheer]

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 to +34??
Regards

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;myid=+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 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.
