[j-nsp] VOIP messages through IPSEC tunnel

[Muhammad Atif Jauahar]

Hi Rehan,

People will correct me if I am wrong. There is option in DHCP to give TFTP
server IP. In case of Cisco IP Phone, when any IP Phone get IP Address, on
reply (from DHCP) it provide TFTP Server IP (which one is of Call Manager
IP).If IP Phone on remote office able to communicate with DHCP (through DHCP
Relaying) they will communicate with Call Manager. In case of Nortel I have
no knowledge this scenario will work or not.

Regards,
Atif.
