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
