Asterisk is not a SIP proxy, so it does not forward SIP traffic to
destinations. In your case, you're likely seeing a 489 response
because Asterisk only knows about specific events in NOTIFY
requests ("refer" for transfers, "message-summary" for outbound
MWI subscriptions, "keep-alive" for certain devices' NAT
keepalives, and "call-completion" for call completion
subscriptions. Anything else is not understood by Asterisk, so you
get a 489 Bad Event response.<br>
<br>
If you want to send NOTIFYs from Asterisk, you must use AMI or the
CLI commands to do so.<br>

<div>I've a SIP endpoint written in Python-AsyncIO that is

<div>When I try to send a SIP NOTIFY to another hardphone

"SIP/2.0 489 Bad event"</div>

<div>In Asterisk, even with debug level on SIP and in console, I
don't have a very interesting message:</div>
<div>[Apr 28 16:57:48] DEBUG[2932]: chan_sip.c:28297

request: b5262f5c-9061-4cb3-86c6-df629fd95a82
</div>
<div><br>
</div>
<div>An idea to have more details about this error ? Or it's
better to use pjsip ?</div>
<div><br>
</div>
<div>BTW, is it possible to send a SIP NOTIFY to another
endpoint via Asterisk, or it's forbidden ?</div>
<div><br>
</div>
<div>PS: I already know it's possible to send SIP NOTIFY via
AMI, I've already used that.</div>
<div>But the idea here it's a tool where we don't need an AMI
access with Asterisk to run.</div>
