I have a SIP trunk from my CUCM over to another PBX (Asterisk). I configured a phone with a BLF which I routed via this trunk.
The CUCM subscribes and I give back an OK. I then go to the other PBX and change the state of the subscribed extension...which generates a notify. CUCM then 200-OKs the Notify, but I never get any change of status on the CUCM phone. The only thing that phone ever acknowledges is that he successfully subscribed.
I see me passing the status I set on my PBX in the "<note>" section of the XML.
Is that the right spot? And...what values should I send?
