Hi all, 
I've read this from iptel website. It is true for SER 0.11.0. 
What about Openser 1.2 ?


"
* Script processing of multiple branches on forking

   Warning


   ser's request processing language allows to make request decisions
   based on current URI. When a request if forked to multiple
   destinations, only the first branch's URI is used as input for script

   processing. This might lead to unexpected results. Whenever a URI
   resolves to multiple different next-hop URIs, only the first is
   processed which may result in handling not appropriate for the other
   branch. For example, a URI might resolve to an IP phone SIP address

   and PSTN gateway SIP address. If the IP phone address is the first,
   then script execution ignores the second branch. If a script includes
   checking gateway address in request URI, the checks never match. That

   might result in ignoring of gateway admission control rules or
   applying them unnecessarily to non-gateway destinations.

   List  of  known  problems  is publicly available at the ser webpage at
   [70]http://www.iptel.org/ser/ . See the "ISSUES" link.
