Something like $mct(key:expiry) = > value? And if expiry is omitted, we use default set in params. Hi Charles, thanks, good to know that you use it. :-) With regards to the expiry value, yes I think this could be implemented like this. Just one remark, the syntax that other PVs uses is "=>", like in http://www.kamailio.org/wiki/cookbooks/3.3.x/pseudovariables#sht_htable_key Then it would be $mct(key=>expiry) = value Best regards, Henning Westerholt

Hello, I want to announce that a new person got developer GIT write access to repository: Hugh Waite - he is quite old contributor by now, with many patches and activity on mailing lists. He is part of the Crocodile RCS team, which developed very important features for Kamailio so far, like websocket and outbound extensions, Lua API and presence/rls improvements. His git commit id is: hpw My warm welcome and looking forward to future work within the project! Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio World Conference, April 16-17, 2013, Berlin - http://conference.kamailio.com -
