<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I suggest reusing the 'media_encryption' pjsip.conf option with possible values of 'yes', 'no', 'attempt'/'try' instead of a new option. If not I suggest renaming the option to something like 'media_encryption_attempt' or 'media_encryption_try'.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">media_encryption isn't a yes/no, it specifies which encryption method to use.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Ah, the sample file with 'media_encryption=no' threw me off. Could possibly have values such as 'attempt_sdes' / 'try_sdes' but then again I don't recall any other values of options being in a format like that. Just a thought. Otherwise I still suggest the option being named something like 'media_encryption_attempt' or 'media_encryption_try'. Or possibly reverse the name to 'media_encryption_force' with a default of 'yes'.</pre>

This means that if you specify SRTP but the client does not support it the session will fail. For situations where this guarantee is not required this new functionality can be used to optimistically use SRTP if possible. This has the added benefit of encrypting the media when possible but does not guarantee it. This also fixes an issue where a client may offer SRTP using the normal transport but we reject it.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Used Blink to place calls with optimistic enabled and disabled on the PJSIP side.
In Blink I alternated between disabled/mandatory/optional.
Confirmed that for each scenario the expected outcome occurred.
Blink Asterisk Result
Disabled Optimistic Off Failed
Disabled Optimistic On Success (Not encrypted)
Mandatory Optimistic Off Success (Encrypted)
Mandatory Optimistic On Success (Encrypted)
Optional Optimistic Off Success (Encrypted)
Optional Optimistic On Success (Encrypted)</pre>
