[OpenSIPS-Users] dialog lifetime refresh issue

[Bogdan-Andrei Iancu]

Hi,

yes, that is true....the idea is the loose_route() function hides the 
dialog matching (for the sequential requests) ; and when this matching 
is done, the lifetime / timeout is updated. So you need to set your avp 
before the matching (the loose_route() ), otherwise it will be ignored.
