[OpenSIPS-Users] Again BLF and Presence with Snom 7xx phones and OpenSips

Wed Mar 4 14:31:15 CET 2015

Hi Bodgan,

thanks for your kind reply. I follow your advices and i saw that NOTIFY
message was sent but looks strange:

NOTIFY sip:5007 at 172.20.1.25:32768 SIP/2.0.
Via: SIP/2.0/UDP 172.20.1.2:5060;branch=z9hG4bK2aa9.80ebc992.0.

From: <sip:5002 at voip.unisi.it>;tag=f315b2d58ae8829149b784764c5a40e3-6e8f.
CSeq: 7 NOTIFY.
Call-ID: 54f6d4095b93-fjqtyt2odvk0.
Max-Forwards: 70.
Content-Length: 147.
User-Agent: OpenSIPS (1.11.3-tls (i386/linux)).
Event: dialog.
Contact: <sip:presence at voip.unisi.it:5060>.
Subscription-State: active;expires=3600.
Content-Type: application/dialog-info+xml.
.
<?xml version="1.0"?>
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="6"           state="full" entity="sip:5002 at voip.unisi.it"/>

Is that correct ?

Thanks, Michele
