Hi,
I want to show a web page with a menu for a door intercom on the display of the phones when a call with the door intercom is active. So the PBX should send a request to the phone to open the browser with that web page.
The phones are VVX 601 with UC software 6.2.0.3937.
The admin manual mentions ssawc and the Access-URL header for this which I'm trying to use.
I have set these options in the config of the phone:
mb.ssawc.enabled="1" mb.ssawc.call.mode="active"
And then I tried sending a SIP request with a Access-URL header during an active call. I tried sending it in a NOTIFY request, as sending these from the PBX would be conveniant:
NOTIFY sip:40@172.17.6.63:53553;transport=TLS SIP/2.0 Via: SIP/2.0/TLS 172.17.6.10:5061;rport;branch=z9hG4bKPje19bc3fa-b1a0-420d-9642-354f57ccfacf;alias From: <sip:40@172.17.6.10>;tag=05936d24-b1d4-4faa-b1ef-daa8f03c08ff To: <sip:40@172.17.6.63> Contact: <sip:40@172.17.6.10:5061;transport=TLS> Call-ID: dd01f7f1-75ad-44a3-9ad4-d44dbe541b75 CSeq: 37798 NOTIFY Subscription-State: terminated Access-URL: <https://pbx.local/door-intercom/>;mode=active Supported: path Max-Forwards: 70 User-Agent: Asterisk PBX 16.7.0 Content-Length: 0
Unfortunately nothing happens. No browser window opens, no icon for passive ssawc appears.
So I also tried sending the Access-URL header like this in MESSAGE and INVITE requests, but that didn't work either. The browser on the phones works otherwise, I can open and use it with a softkey.
So in which kind of SIP requests are Access-URL headers recognized and acted upon? Or did I format the header not in the correct way?
Thanks.
Kind regards,
Gerd

unfortunately it is not easy to add custom headers to these requests on Asterisk-based PBXes that use PJSIP.
I'll have to use the push interface of the webinterface of the phone then.
Thank you for your help.

Thanks for your answer.
If reading the article you linked with my question of the valid SIP requests in mind, it seems like ssawc only works during the initial invite of a call and I can not trigger it once the call is connected.
Is this correct or is there a way to trigger it for an already connected call?
