[OpenSIPS-Users] Presence and Linksys phones - not working 1.6.1

[James Lamanna]

Hi,
I'm trying to get presence (BLF) working with some Linksys 942 phones.
I've noticed that I get the error,
handle_subscribe: Missing or unsupported event header field value

I did a trace and the phone is trying to subscribe to the "x-spa-cti" event.
Is there a way to support/fix this? Is there something that supports that event?

Thank you.

This is opensips 1.6.1.
