Hi, AFAIK it's not possible to use "kamctl ping" to send an OPTIONS using TCP. I've tryed: kamctl ping sip:user at domain;transport=tcp but it doesn't work. I'm inspecting script/kamctl script and have no very clear what to check. Is it feasible to send the OPTIONS ping via TCP? Thanks. -- Iñaki Baz Castillo <ibc at aliax.net>
