Create joint capabilities.
Creates a list of joint capabilities between the given remote capabilities, and local ones. "local" and "remote" reference the values in ast_sip_call_codec_pref.
remote | The "remote" capabilities |
local | The "local" capabilities |
media_type | The media type |
codec_pref | One or more of enum ast_sip_call_codec_pref |
A | pointer to the joint capabilities (which may be empty). NULL will be returned only if no memory was available to allocate the structure. |

Create joint capabilities.
Creates a list of joint capabilities between the given session's local capabilities, and the remote capabilities. Codec selection is based on the session->endpoint's codecs, the session->endpoint's codec call preferences, and the "remote" capabilities passed by the core (for outgoing calls) or created by the incoming SDP (for incoming calls).
session | The session |
media_type | The media type |
remote | Capabilities received in an SDP offer or from the core |
A | pointer to the joint capabilities (which may be empty). NULL will be returned only if no memory was available to allocate the structure. |

Create a new stream of joint capabilities.
Creates a new stream with capabilities between the given session's local capabilities, and the remote stream's. Codec selection is based on the session->endpoint's codecs, the session->endpoint's codec call preferences, and the stream passed by the core (for outgoing calls) or created by the incoming SDP (for incoming calls).
session | The session |
remote | The remote stream |
A | pointer to a new stream with the joint capabilities (which may be empty), NULL will be returned only if no memory was available to allocate the structure. |
