Hi Agalya, Very specific to your scenario for 180 without SDP , There can be 2 scenarios based on which it depends whether to send all forked 180 or not . A side fork not supported :First 180 sent and next 180 with different to-tag is consumed by proxy A side fork supported : Both 180s relayed to A.
>>>>Is this right behavior of proxy or it should forward only the ringing response in which call leg it has been answered ? As mentioned there is no harm in relaying forked 180s if A supports fork, later when final success response comes it can be relayed too.
