SUBSCRIBE messages receive 489 and 406

Asterisk Asterisk Support
1

Hi,

I have installed Asterisk 11 recently and am able to REGISTER my SIP client (MTA).

The SIP client tries to SUBSCRIBE for event =reg which receives 489 Bad event from the Asterisk

and it also sends SUBSCRIBE for event = message-summary which receives 406 Not Acceptable.

sip and extension conf files attached. I have already tried allowsubscribe and hint but nothing works (might have not done it right)

Please let me know how to get the SUBSCRIBES working.

SUBSCRIBE (event=reg) is to NOTIFY the device about registration states
SUBSCRIBE (event = message-summary) is to subscribe for VM service.

SIP Traces attached.

“reg” is not a supported event type.

Asterisk requires application/simple-message-summary to be the only acceptable format for message summary events, at least in the version I checked. That’s probably a misfeature, but I believe the client is also in error by specifying formats that it would not be able to handle for message summaries. Actually, it will handle other formats, but only if they are on separate lines.

The accepted events appear to be:

presence
dialog
message-summary
call-completion

Thanks for the response David, now I know why the event: reg are being rejected.

But what i don’t understand is, the client sends a SUBSCRIBE with Event: message-summary and receives a 406. Please could you help me with this. Is Event: message-summary supported in Asterisk 11? Or do I need to upgrade\update to other versions.

Thanks

Asterisk is objecting to the Accept line, not the Event. If Accept is present, there must be a line consisting only of:

Accept: application/simple-message-summary

and the peer should only be listing formats that it can accept and process as results of SUBSCRIBE.

6

So, If the client sends the SIP request as below, with Accept header only with application/simple-message-summary, this should work?

That’s what my reading of the code says.
