option 125 issue

[Kraishak Mahtha]

Hi

I have isc dhcp appliance on my local environment and for mitel(VOIP  phones)
to work .
I tried to assign the option 125 with value id:ipphone.mitel.com
;sw_tftp=3.2.5.6;call_srv=1..3.6.4;vlan=1;l2p=6;
but still i see the issue, when i search on google forums, few of them say
that semicolon is not accepting and they tried with some hexadecimal
concept but for me after updating the dhcp config I tried with syntax check
command but it is not throwing any error
[root at server1 ~]# cat dhcpdtest.conf
subnet 192.168.3.0 netmask 255.255.255.0 {
       option subnet-mask 255.255.255.0;
       option routers 192.168.3.1;
       option domain-name "test.com";
       option vivso "
ipphone.mitel.com;sw_tftp=3.2.5.6;call_srv=1..3.6.4;vlan=1;l2p=6
;";
}
[root at server1 ~]# dhcpd -t -cf dhcpdtest.conf
Can anyone has idea about this? will the option 125 needs to be in
hexadecimal format only to work or is it can be normal string ?
If it accepts only hexadecimal they why is the dhcpd syntax checker command
is not throwing error?

Thanks in advance
