I have a small business customer where we deployed a HPBX phone system. The ASA is acting as the DHCP server for the data and voice vlans. Every PC and phone are functional. There is one phone that I had to assign a static IP since the ASA cannot do DHCP by MAC reservation.
I assigned the correct IP, GW, Mask and DNS servers (184.108.40.206 / 220.127.116.11). I also allowed access from the TFTP server into the firewall. The phone registers fine by contacting the SIP server, but it doesn't update its config since it cannot access the TFTP server. I ran several captures of the phone booting up and in response to the DNS query, I see "No such name". I am not sure what else I can try. Any ideas?
Thanks in advance,
