Cisco IP phone anyconnect VPN with ASA

Hello everyone!

Have been using this feature for more than a year now, one or two phones in remote locations (other countries) fail to register with CUCM. Display stays at "Registering" but nothing happens. VPN is up since I can see the phone obtaining an IP address and I can also see it in ASDM

What can be a cause of this problem? Slow internet upload bandwith?

Thank you!

Hi

Ensure the DHCP scope is delivering the TFTP address to Phone... probably the option 150 is missing, also if the FW isn´t blocking the registration

I hope this help, please rate this post
