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

[Bogdan-Andrei Iancu]

Hi Michele,

The problem in your script is that you do not handle the sequential 
(in-dialog) SUBSCRIBE requests (as you have the second one in your 
trace, ending with 404 and terminating the subscription).

In the " if ( has_totag() ) " block, you have:
} else {
         if (is_method("SUBSCRIBE") && $rd == "127.0.0.1:5060") { # 
CUSTOMIZE ME

The $rd detection does not cover all your cases, as you configure the 
presence module to advertise as SIP contact 
"sip:presence at voip.unisi.it:5060". So, the test fails.

You can adapt the test like:
         if (is_method("SUBSCRIBE") && $rd == "voip.unisi.it") { # 
CUSTOMIZE ME

Or set the contact in presence with the real IP:
modparam("presence", "server_address", "sip:presence at 127.0.0.1:5060")

Best regards,
