Lync 2013 Client and Remote Call Control – CUCM

Yes, I know. Remote Call Control (RCC) is dead in the world of Lync. Well, it’s not dead yet, but I am sure it will get fully clubbed over the head soon.

This issue reared its ugly head the other day when upgrading Lync 2010 clients to Lync image2013 clients. Every time you would start Lync 2013, it would generate this warning pop-up:

Cannot apply your new call forwarding settings. To turn off call forwarding, click OK. To ignore this error, click cancel.

If you click OK, it goes away until the next time you sign into Lync 2013. If you click Cancel, it goes away until the next time you sign into Lync 2013. Basically, nothing gets rid of it. This does not happen if you are using Lync 2010, though.

The reason? Well, Cisco… Yep, it isn’t a Lync 2013 issue, even though it appears to be it’s fault. Lync 2010 doesn’t experience because it doesn’t care what the Cisco Unified Call Manager tells it.

Basically, the issue is that CUCM tells the Lync 2013 client that call forwarding is set, even though it isn’t. See the Cisco Bug report for more info. The good news is that Cisco is going to fix it. Hopefully, it won’t be too long.
