Flash-based Audio in Openfire part II

each flash client is a sip client/device and requires individual registration accounts. If you want a single telephone number to ring all sip accounts, then use a PBX like asterisk and modify you dial plan to fork the call to the multiple sip devices or use queues, groups or agent devices.

Ok got this to run


But get a screen where it asks me for username / sip server etc. I get it to tell me… Connection Success…after I logon…is it supposed to give me a phone to dial from at this point or is that another piece?



AMAZING!!! i need something like that!!! plz!!

While using the SIP phone we’ve experienced poor sound quality. In following this thread, we did find two different versions of cygwin1.dll on our server. We have AsteriskWin32 installed on the same server as Openfire with the Red5-plugin. AsteriskWin32 is using the cygwin1 version and Red5Plugin is We have Cygwin on this server and want to keep this instance of AsteriskWin32. How do we recompile Asao2ulaw? Any suggestions are appreciated.


This is advise given in AsteriskWin32 forum in the attached thread;


Don’t install cygwin1.dll in the windows system folders! Never!!!

Install Cygwin from cygwin.com

Remove the version of cygwin1.dll included with your application and as well the version provided with asterisk, also remove other executables and DLLs which are duplicated with some third party packages.

Put c:\cygwin\bin into your system path.

IMO it is wrong to distribute Cygwin with an application, it is just the runtime and everyone should install it from cygwin.com when it is needed.
