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

[sai sudheer]

hii,,
I tried {uri.user} from the URI transformations. but i just get 0 or Null in the log.

Now i tried the string transformation as per your reply, and {s.select,index,separator} is thing i was expecting .. 
It worked now, and i am getting +34xxx alone, which is what i need. 

Thanks a lot.

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 to +34??
