Resolved Issues
This release contains the following resolved issues:
For better interoperability with other components, SIP Endpoint SDK now uses uppercase "H264" in the SDP for H.264 video codec. Previous versions used the lowercase “h264” (which was not a bug since the standard defines the codec name in SDP to be case-insensitive), but was found to cause problems with some endpoints. (SEPSDK-3005)
SIP Endpoint SDK now allows configuring multiple profiles for H.264 video codec, by using #n suffix added to the codec/section name for additional parameter sets, for example:
<domain name="codecs">
<section name="enabled">
<setting name="audio" value="pcmu,pcma,g729"/>
<setting name="video" value="h264,h264#2"/>
</section>
<section name="h264">
<setting name="payload_type" value="108"/>
<setting name="fmtp" value="profile-level-id=420028"/>
</section>
<section name="h264#2">
<setting name="payload_type" value="114"/>
<setting name="fmtp" value="profile-level-id=42e01e"/>
</section>
</domain>All configured 'fmtp' values will be added (with corresponding payload type) to the offer SDP sent by SIP Endpoint SDK. Incoming video offer with multiple H.264 profiles is always accepted if offered parameters can be supported, even when they are not explicitly listed in the configuration. (SEPSDK-3004)
Processing of TLS exceptions for SIP connections is improved to ensure the previous SIP dialog is properly deleted. In previous versions, earlier dialogs might remain active and re-submit the registration renewal later potentially with wrong contact info. (SEPSDK-3003)
