Currently chan_pjsip on receiving a re-INVITE without SDP will only return the codecs that are previously negotiated and not offering all enabled codecs. This causes interoperability issues with different equipment (e.g. from Cisco) for some of our customers and probably also in other scenarios involving 3PCC infrastructure. According to RFC 3261, section 14.2 we SHOULD return all codecs on a re-INVITE without SDP The PR proposes a new parameter to configure this behaviour: all_codecs_on_empty_reinvite. It includes the code, documentation, alembic migrations, CHANGES file and example configuration additions. ASTERISK-30193 #close Change-Id: I69763708d5039d512f391e296ee8a4d43a1e2148
DO NOT REMOVE THIS FILE!
The only files that should be added to this directory are ones that will be used by the release script to update the CHANGES file automatically. The only time that it is necessary to add something to the CHANGES-staging directory is if you are either adding a new feature to Asterisk or adding new functionality to an existing feature. The file does not need to have a meaningful name, but it probably should. If there are multiple items that need documenting, you can add multiple files, each with their own description. If the message is going to be the same for each subject, then you can add multiple subject headers to one file. The "Subject: xxx" line is case sensitive! For example, if you are making a change to PJSIP, then you might add the file "res_pjsip_my_cool_feature.txt" to this directory, with a short description of what it does. The files must have the ".txt" suffix. If you are adding multiple entries, they should be done in the same commit to avoid merge conflicts. Here's an example:
Subject: res_pjsip Subject: Core
Here's a pretty good description of my new feature that explains exactly what it does and how to use it.
Here's a master-only example:
Subject: res_ari Master-Only: True
This change will only go into the master branch. The "Master-Only" header will never be in a change not in master.
Note that the second subject has another header: "Master-Only". Changes that go into the master branch and ONLY the master branch are the only ones that should have this header. Also, the value can only be "true" or "True". The "Master-Only" part of the header IS case-sensitive, however!
