Donat Zenichev	8e1a41a9ec	MT#59962 core: introduce new RTP transport model ... This commit introduces a new RTP transport model, based on the AmRtpTransport abstraction, providing a more modular and efficient approach to RTP handling compared to the legacy model. General things: - Introduction of new RTP receiver and transport abstractions - The new model coexists with the legacy RTP handling to preserve backward compatibility Architecture overview: - A new AmRtpTransport layer is introduced to encapsulate RTP transport logic and decouple it from AmRtpStream and session-level code - Transport-specific functionality is implemented via dedicated classes: - AmRtpTransport: base abstraction responsible for RTP/RTCP packet flow, lifecycle management, and interaction with streams - AmRtpUdpSocket: UDP-based RTP socket implementation - AmRtpSocketPair: manages RTP/RTCP socket pairs and their coordination - AmRtpStream is refactored to rely on the transport interface instead of directly managing sockets and low-level I/O Integration details: - SIP session and dialog logic (AmSession, AmSipDialog) is updated to work with the new transport model - SBC call legs and call profiles are extended to support transport selection and lifecycle handling - SDP processing (AmSdp) is updated to reflect transport capabilities and address handling changes This refactoring improves separation of concerns, reduces coupling between RTP streaming and transport mechanics, and provides a cleaner foundation for future RTP extensions and optimizations.

Daniel Grotti	f56366737c	MT#58584 Do not add outbound_proxy in Route if exist ... When outbound PRACK is challanged, SEMS is regenerating the PRACK to proxy duplicating the proxy socket in the Route header, with the result of: Route: <sip:127.0.0.1:5062;lr>, <sip:127.0.0.1:5062;lr=on;ftag=xyz;leg_b=1;did=f85.d281>, <sip:127.0.0.1;r2=on;lr=on;ftag=xyz;ngcplb=yes>, <sip:192.168.178.104;r2=on;lr=on;ftag=xyz;ngcplb=yes> the duplicate "127.0.0.1:5062" is causing routing issue on proxy, cause loose_route() function removes only the first element. Then proxy sends PRACK to itself. To avoid that, we make sure is SEMS to do not add the 'outbound_socket' value in the Route header if that value already exist in the first position.

Daniel Grotti	cdcbbb7866	MT#57562 sems (CE): Add Allow header in 200 OK when empty ... This is a partial rework of b67428d. The patch was always saving the Allow header from the initial INVITE and replacing the Allow header in the 200 OK with that. This fixed an issue with AA, where Allow header in the 200 OK, generated by the AA, was empty. But it causes an issue in case of normal calls between A and B. In general we want to keep the Allow header in the 200 OK, if exist. Instead, we want to add the Allow header in the 200 OK response in case the 200 OK does not contain the Allow header. In this case we won't set the original Allow from the INVITE but instead we will set a default Allow header (SIP_REPLY_DEFAULT_ALLOW) containing all the major SIP method.

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.
