On the inside, we have CUCM 8.5(1). When using IP Communicator soft phone running SIP protocol or Cisco Mobile 8.1.1 for iPhone client on the internal wireless, everything works fine. <br><br>When you connect the same client from the outside world using AnyConnect VPN or IPSec VPN, the client registers to CUCM properly and calls initiated outbound from either device work properly. However, inbound calls to either device never ring the phone. I did a packet capture on the ASA and see 6 total messages in both direction so I know two way communication is present. One of the messages is a <b>404 Not Found</b> error, which doesn't seem to tell me much. If I reconfigure the IP Communicator to use SCCP and connect via VPN, it works fine. But the problem always occurs when SIP protocol is used. <br><br>Since the calls work fine on the inside of the network, this doesn't appear to be a CUCM problem. The only variable is VPN through the ASA using SIP protocol. I have tried to disable SIP inspection on the ASA, but that broke all calls from those devices. <br><br>Is anyone successfully using the Cisco Mobile for iPhone client connected via a VPN and receiving inbound calls? <br><br>Thanks,<br>Brian<o:p></o:p></p></div></body></html>
