1. After transferring a video call the video may be missing
With the default settings of the WCS server the video may be missing after transferring a video call.
In this case you need to add the following setting to /usr/local/FlashphonerWebCallServer/conf/flashphoner.properties:
video_streamer_generate_seq=true
2. It's impossible to make a SIP call if 'SIP Login' and 'SIP Authentification name' fields are incorrect
Symptoms: SIP call stucks in PENDING state.
Solution: according to the standard, 'SIP Login' and 'SIP Authentification name' should not contain any of unescaped spaces and special symbols and should not be enclosed in angle brackets '<>'.
For example, this is not allowed by the standard
sipLogin='Ralf C12441@host.com' sipAuthenticationName='Ralf C' sipPassword='demo' sipVisibleName='null'
and this is allowed
sipLogin='Ralf_C12441' sipAuthenticationName='Ralf_C' sipPassword='demo' sipVisibleName='Ralf C'
