The SIP channel driver does not support flash events. The most that it<br>
will support is passing through a flash event received from another SIP<br>
UA. It will not send flash events itself.<br>

Typically, questions such as these are best handled on the asterisk-users<br>
mailing list. asterisk-bugs is typically used for commenting on a JIRA<br>
issue (typically to have it opened or closed). Users on asterisk-users<br>
may have some suggestions for you; however, unless a patch is written that<br>
implements handling the AST_CONTROL_FLASH frame in chan_sip, there probably<br>
isn't much you can do.<br>
<br>
Patches, of course, are welcome.<br>
<br>
Note that an issue already exists for this limitation in chan_sip - see<br>
ASTERISK-17372 (although it does not appear as if the patches on that issue<br>
will fully resolve the problem either).<br>
