High battery consumption with proxies that don't support IMDN

[brianjmurrell]

When configured to use a proxy that doesn't support IMDN (I.e. Asterisk AFAIK), linphone-android will consume a lot of battery repeatedly sending IMDN messages to the proxy only to receive SIP/2.0 415 Unsupported Media Type responses. This happens repeatedly, draining battery.

A work-around is to set im_notif_policy=none in the [sip] section of linphonerc and build a custom version of the app.

But for people using a version from a repository, this is not possible. There are two solutions here:

1. Provide a UI element to disable IMDN
2. Don't repeatedly send IMDN messages after receiving a SIP/2.0 415 Unsupported Media Type response from a proxy.

The first solution of course requires the user to know that their proxy doesn't support IMDN and disable the option. The second option is more automatic.

SDK issue, not Android.

Which project at https://github.com/BelledonneCommunications should this be filed with then? There are no projects with sdk in the name even.

Is https://github.com/BelledonneCommunications/linphone the SDK?

It's the top project of the SDK so yes you can open it there.
