Subject: [OpenSIPS-Users] Presence Error messages

I am attempting to troubleshoot what I think is a presence/b2b_sca issue.

I keep getting an error message from presence as follows:
ERROR:presence:update_presentity: No E_Tag match [ff5ad69c9be06cffaa136492f4fb3b50]

ERROR:presence:handle_subscribe: in event specific subscription handling

The outbound call is being attempted from a Cisco SPA525G2, and the message on the phone screen shows "no line"-despite happening at a time when it is known there are no calls on the system that I can see.  The observed behavior of the phone is to show "No line", and the phone itself gets a

What do these error messages mean?  What is the system trying to tell me?  I am trying to get my brain around what the error messages are saying so I can figure out where to look next in my troubleshooting.  The proxy is functioning well in all other respects.
