Connection failed on 7925G screen when receiving a call

[Thiago Gandara]

Hi voice team, i have a problem on my custumer site, sometimes when a wireless phone 7925G or 7921G receive or made a call appears on the screen the message: Connection failed, and the person can´t answer or do the call.

Obs: Attached are the picture of the message (in portuguese).

Thanks in advanced,

Thiago Gándara.

Have you looked at the logs on the phone or on your controller/WCS/Wireless network? 

Are those call drops specific to an area with in your location? 

How is call quality on the rest of your VoWiFi experience? 

This doc is really useful in troubleshooting issues on those phones:  http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7925g/7_0/english/administration/guide/7925trb.html
