[Serusers] variables in ser.cfg

Hi all, is there a possibility to use variables in ser.cfg (ser0.9.0) like ... set myip=192.168.1.11 set myaccount=testuser set mypasswd=testpasswd ... modparam("uac","credential","$myaccount:$myip:$mypasswd"); ... rewritehost($myip); ... Perhaps a solution would be with avpops, but I didn't get it to work in conjunction with dbtext. Has someone an example how to read variables with avpops out of a dbtext table which are not connected to a SIP-message? (I read the README for avpops!!) Any other solutions would be a help!! Would this be possible with openser's pseudo variables or another ser-version? Thanks Thorsten
