To send a channel message, you must first join the channel. Channel names are URIs that are formatted by using the issuer string. In this example scenario, join "sip:confctl-g-xyzzy.test@mt1s.vivox.com", which is a g-type (general) channel that is controlled by issuer "xyzzy". The user Alice joins a channel, as detailed in the following code:
[SDKSampleApp]: addsession -c sip:confctl-g-xyzzy.test@mt1s.vivox.com* Adding channel sip:confctl-g-xyzzy.test@mt1s.vivox.com (muted=no) (audio=yes) (text=yes) to session group sg_sip:confctl-g-xyzzy.test@mt1s.vivox.com with handle sip:confctl-g-xyzzy.test@mt1s.vivox.com* Issuing req_sessiongroup_add_session with cookie=4* Request req_sessiongroup_add_session with cookie=4 completed.* evt_sessiongroup_added: sg_sip:confctl-g-xyzzy.test@mt1s.vivox.com [.xyzzy.alice.]* evt_session_added: sip:confctl-g-xyzzy.test@mt1s.vivox.com [sg_sip:confctl-g-xyzzy.test@mt1s.vivox.com]* evt_text_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_text_connecting* evt_media_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_media_connecting 'Success' (0)* evt_text_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_text_connected* evt_participant_added: sip:confctl-g-xyzzy.test@mt1s.vivox.com sip:.xyzzy.alice.@mt1s.vivox.com* evt_media_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_media_connected 'Success' (0)
Alice then sends a channel message, as detailed in the following code:
[SDKSampleApp]: message -m "bob are you in channel?"* Sending message 'bob are you in channel?' to session handle sip:confctl-g-xyzzy.test@mt1s.vivox.com* Issuing req_session_send_message with cookie=5* Request req_session_send_message with cookie=5 completed.
The other user Bob joins the same channel, as detailed in the following code:
[SDKSampleApp]: addsession -c sip:confctl-g-xyzzy.test@mt1s.vivox.com* Adding channel sip:confctl-g-xyzzy.test@mt1s.vivox.com (muted=no) (audio=yes) (text=yes) to session groupsg_sip:confctl-g-xyzzy.test@mt1s.vivox.com with handle sip:confctl-g-xyzzy.test@mt1s.vivox.com* Issuing req_sessiongroup_add_session with cookie=3* Request req_sessiongroup_add_session with cookie=3 completed.* evt_sessiongroup_added: sg_sip:confctl-g-xyzzy.test@mt1s.vivox.com [.xyzzy.bob.]* evt_session_added: sip:confctl-g-xyzzy.test@mt1s.vivox.com [sg_sip:confctl-g-xyzzy.test@mt1s.vivox.com]* evt_text_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_text_connecting* evt_media_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_media_connecting 'Success' (0)* evt_message: sip:confctl-g-xyzzy.test@mt1s.vivox.com sip:.xyzzy.alice.@mt1s.vivox.com bob are you in channel?* evt_participant_added: sip:confctl-g-xyzzy.test@mt1s.vivox.com sip:.xyzzy.alice.@mt1s.vivox.com* evt_text_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_text_connected* evt_participant_added: sip:confctl-g-xyzzy.test@mt1s.vivox.com sip:.xyzzy.bob.@mt1s.vivox.com* evt_media_stream_updated: sip:confctl-g-xyzzy.test@mt1s.vivox.com session_media_connected 'Success' (0)
Although Bob joined after Alice, because the channel message history policy has been enabled on this server, Bob sees the message (message event) "bob are you there?".
