Hello, have a look to the transformations for URIs: https://www.kamailio.org/wiki/cookbooks/devel/transformations#uri_transform… 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.

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

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.  On Wednesday, October 14, 2020, 08:36:37 AM GMT+1, Henning Westerholt &lt;hw(a)skalatan.de&gt; wrote: Hello,   can you share the error you have got?
