[sr-dev] [kamailio/kamailio] 180 Ringing without Contact with TOPOS enabled (#1720)

[Henning Westerholt]

You are right, according to the RFC the Contact Header is optional in 1xx: https://tools.ietf.org/html/rfc3261#section-20.1
The RFC says as well that it SHOULD be included, but it is not a MUST.
