[Users] Problem with Asterisk - Openser Voicemail integration

Hello, I am trying to setup a voicemail solution based on the tutorial published on voip-info.org called "Realtime Integration of Asterisk with OpenSER" ( http://www.voip-info.org/wiki/view/Realtime+Integration+Of+Asterisk+With+Op…) and I face an issue. I followed the steps carefully, and I am about to start running the openser server. But when I try to launch the server, two lines are troublesome. My first error is the following : 0(0) ERROR:avpops:fixup_write_avp: bad attribute name in param 2 <i:10> 0(0) ERROR: fix_actions: fixing failed (code=-1) at cfg line 133 It is related to the following line of the openser.cfg : avp_write("$ruri", "i:10"); Then, I comment the line, and another error appears : 0(0) ERROR:avops:fixup_pushto_avp: bad param 1; expected : $pseudo-variable ... 0(0) ERROR: fix_actions: fixing failed (code=-1) at cfg line 200 It is realted to the line : avp_pushto("$ruri", "i:10"); I have the dialplan writen in the tutorial and I run the latest stable version of OpenSER : openser-1.1.0-notls Hopefully someone encontered the same issue, and managed to solve it. Thank you in advance, Antoine
