Even if this is required by RFC, the fact is that it's not needed at
all for this stuff to work.

Also right, but due the design of OverSIP (basically an Outbound EDGE
proxy) it was easier for me to always use double Record-Route and
double Path header. In Outbound (RFC 5626) the Record-Route header
added by the EDGE proxy contains a username in the URI that identifies
the client connection. For some reasons it was easier always to use
double Path.

Anyhow, consider also the case in which there are two proxies between
clients and OpenSIPS, so increasing the size of the "path" column is
