We have discovered that BLF does not work properly on the GXP2130 phones due to a SIP compliance issue with the phones. According to RFC 3265 (which governs SIP Event Notifications protocol) permits empty body NOTIFY body. This makes the phones not fully compliant with SIP standards. We would like to see this fixed with a firmware upgrade ASAP.
Your website is really cool and this is a great inspiring article. Thank you so much.
