Start a Accept method call.

Accepts the updated Description and update the corresponding local description. If FurtherNegotiationRequired is True, calling this method will generally cause a network round-trip and a new MediaDescription to be offered (hopefully with FurtherNegotiationRequired set to False).

`proxy` : | the TpProxy
`timeout_ms` : | the timeout in milliseconds, or -1 to use the default
`in_Local_Media_Description` : | Used to pass an 'in' argument: The local description to send to the remote contacts and to use in the <tp:dbus-ref namespace="ofdT.Call1">Content</tp:dbus-ref>.
`callback` : | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking
`user_data` : | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL`
`destroy` : | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL`
`weak_object` : | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL`
Returns : | a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

### tp_cli_call_content_media_description_call_reject ()

    TpProxyPendingCall * tp_cli_call_content_media_description_call_reject

Start a Reject method call.

Reject the proposed update to the remote description.

`proxy` : | the TpProxy
`timeout_ms` : | the timeout in milliseconds, or -1 to use the default
`in_Reason` : | Used to pass an 'in' argument: A structured reason for the rejection.
`callback` : | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking
`user_data` : | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL`
`destroy` : | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL`
`weak_object` : | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL`
Returns : | a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.
