Donat Zenichev	aec816dad7	MT#56321 Add 'Allow:' header to the 200OK, if present in the request ... We have to take care of keeping the actual 'Allow:' header in the request, if the incoming request has had it. One of the use cases for that is for example the INVITE coming to the AA, when we must respond with the 200OK, but there is no 'Allow:' header inside the 200OK. Certain systems can be confused by that, even though the RFCs are not forcing us to do so. Which can even lead to an impossibility to use a normal call clearing with the BYE method, from behalf of the caller. Change-Id: I9bafb89e4aa5e53077450068f847c07a497b43f1	3 years ago
Donat Zenichev	91cd45fe7b	MT#56321 Treat 183 as 200OK (other leg), when early media forced ... There is a need to add an exception processing for 183 Session Progress, and the following in-dialog requests/responses, in case the 183 has been previously sent to the B2B with the hf 'P-Early-Announce: force'. This adds the following behavior. When 183 is received, and the caller has been updated with the new media capabilities, according to those needed to embed early media into the media session with the caller (via re-INVITE), then: - even though the 183 is treated similarly to 200OK in terms of media updates, do not send ACK to the leg going towards DSM, becausethe sems-b2b giving the DSM, it's still in stage INVITE/183 - do not re-negotiate the leg going towards the DSM, after the caller has been updated with the new media (a usual behavior) because the sems-b2b giving the DSM still considers the dialog here in the Early stage - do not set the leg going towards DSM into the Connected state, because by the fact, it's still in the Early stage, and setting of it into the Connected state, will break processing of BYE / CANCEL. - upon receiving the BYE from the caller (after the DSM announce is heard), answer right away with 200OK, but do not forward BYE to the let going towards DSM. Instead initiate the CANCEL towards it, because this leg is technically still in the Early stage of the dialog.
