Description

This setting is effective only when RTP encryption (SRTP) is also enabled and is used to specify whether the use of the RTP/SAVP profile by the phone should be off (for backward compatibility), optional or mandatory.When this setting is set to "mandatory" the phone will offer and accept only SDPs that contain m= lines with an audio profile of RTP/SAVP.When this setting is set to "optional", the phone will offer SDPs containing two m= lines, one with an audio profile of RTP/SAVP the other with an audio profile of RTP/AVP and it will accept SDPs containing m= lines with either profile. The RTP/SAVP profile, being the preferred one, is listed first. Since some SIP proxies cannot handle RTP/SAVP profiles or multiple m= lines this setting may also be turned off. In this case the phone will send SDPs containing RTP/AVP audio profiles only. Whether the crypto attribute is included depends on whether RTP encryption is on or off.


When RTP encryption is turned off this setting has no effect.
