[OpenSER-Users] Remove header from Cancel

Hello. Is it possible to remove Route: -header from Cancel requests. I have an user agent that inserts Route: -header in Cancel requests. I've already tried to get rid of it with remove_hf("Route") function, but it did not have any effect. From what I understand is, that this header is quite unnecessary in a stateful proxy, because the Cancel messages are handled hop-by-hop basis. It's just that it causes problems at the next hop proxy. I didn't even know about this problem with the UA before I started using the development version of OpenSER, the 1.2.2 version removed the Route: -header automatically before relaying Cancel forward. Thank you JN
