I have no idea if this will be the case for everyone, but we had this error for a user here today. The only odd thing I could find was that the user's phone for some reason was associated to 3 different end user profiles in CUCM. We removed the extra user associations and that resolved the issue right away.
Maybe just a coincidence but it's worth checking if you have the same error coming up.

Hello all, I have a question I have not been able to find answered anywhere else. My user has SNR successfully configured on his Cisco line, with the destination being his cell phone. So far so good, but the problem is when he tries to call into the site (e.g. to a co-worker's DID line) from that same cell phone, the call fails immediately. This started after SNR was configured. Not being too familiar with this configuration, I set up a similar SNR config on my own phone, to my cell phone, then tried to call my co-worker's DID and found that it, too, failed. I can only guess this is some kind of loop-prevention mechanism, but it seems like that should only be a factor when dialing one's own IP phone from the destination cell phone--not immediately upon calling anyone in the deployment. Any suggestions on where I might be able to tweak a CSS or otherwise to get around this? Or is this just how it works? Thank you! Edit: Well if anyone ever needs to know, I eventually figured this out. For the Remote Destination Profile, I switched the main CSS to one that does not include any valid route pattern for the cell phone number. Left the Rerouting CSS set to one that does route to it. That seemed to clear everything up.
