[sr-dev] routing time of sip request

eu is asking operators to provide all kinds of statistics about their telephone service. one of the attributes is routing time of sip request, i.e., in/out delay of sip requests. in order to be able to do something like that, we could have a pseudo variable that provides ms timestamp value or, perhaps better, a way to zero a ms counter and then store its current value to a pseudo variable in onsend_route. the problems seems to be that according to core cookbook, it is not possible to set pseudo variables in onsend_route. comments? -- juha
