Alcatel Unleashed

hi

as per technical documentation a have a remote site connected by a IPSEC vpn tunnel.

i have a number of IP phones connected (fixed ip address) and im trying to connect a IP DAP

i have comissioned a raspberry PI and installed a DHCP program onto it.

i have allocated it a fixed IP address and programmed a range for the DAP and the ALE handsets.

To allow me to program the RASPBERRY as a DHCP/TFTP server i have to ensure there are 5 entries ; as per Expert docs

#TELEPHONE NETWORK
subnet 192.168.221.100 netmask 255.255.255.0 {
range of 192.168.221.10 192.168.221.50;
option router 192.168.221.1;
option voip-tftp-router 192.168.21.246;
}

the last line is not working and apparantely i need a 5th line (file name)...... can anyone help ?

DECT DAP needs IP multicast for signalling. IPsec itself is IMHO unable to route multicast packets. It may be necessary to use a L2 protocol on top of IPsec which is able to forward multicast, for instance GRE. To find out the needed file name option for DHCP I would deploy IP DECT on a local site and trace the DHCP traffic.
