Hi everone, I am having a strange issue with SIP integration between CUCM and Unity Cnx. I pickup the handset on extention 2001 and dial 2004, 2004 does not answer, call transfers to Voicemail, and this is where the issue starts, Unity plays the Attempt to sign in message and prompts to enter the PIN for 2001 instead of transferring the call to extension 2004's inbox.
I have run some debugs and noticed the below, the RedirectingId= field is empty. I have tried this from two different CUCMs into the same Unity and both have the same issue. However both CUCMs work with SCCP integration into the same Unity Cnx Box.
