[OpenSIPS-Users] media-relay exception

[nick at uni-petrol.com]

 I just updated python to 2.6 version but still have same error.
 I have installed following version of libs:

 python26.x86_64                            2.6.5-6.el5
 python26-libs.x86_64                       2.6.5-6.el5
 python26-application.noarch                1.1.5-3
 python26-cjson.x86_64                      1.0.5-4
 python26-gnutls.x86_64                     1.1.9-1
 python26-twisted-core.x86_64               8.2.0-3
 python26-twisted-names.x86_64              8.2.0-3
 python26-zope-interface.x86_64             3.3.0-1

 I can give you ssh access to openvz virtual environment to fix this 
 error or I can do some debugging if you write me what I need do.
 Is it possible to resolve this problem?
