Dhcpd config for Polycom IP 4000

Hello,

I managed to configured and get online two Polycom Soundstation 4000 and they worked great. As part of this I configured the dhcpd. Then later I detected on the Asterisk that the dhcpd server didn’t start up. I could not get it to work without having to revert back to my old configuration. The fact that it did not start up made a few of my snom phones go off line. So I had to sacrifice my Polycom config and revert back to get these snom phones online. But now, of course, when I reboot a Polycom it doesnt go back online again. I think this is a very simple problem to resolve and if some helpful soul could have a look at it that would be great.

Possibly I do not need this group thing below. I cannot say for sure.

The Asterisk sits on the same side of the firewall as the Polycom.

Here is my initial dhcpd (without Polycoms), this one works for all other purposes but not with for starting up Polycoms:

ddns-update-style interim;
ddns-update-style interim;


subnet ipaddress.of.myserver netmask 255.255.255.0 {
ddns-updates on;
option routers ipaddress.of.myserver;
option domain-name-servers dns.of.the.isp;
range dynamic-bootp ipaddressrange;
}

here is the dhcpd with the Polycom config in it:

ddns-update-style interim;
ddns-update-style interim;

option boot-server code 66 = string;

subnet ipaddressofmyserver netmask 255.255.255.0 {
ddns-updates on;
option routers ip.address.ofmyserver;
option subnet-mask 255.255.255.0;
option domain-name “yourdomainname.com”;
option domain-name-servers 172.31.0.12, 172.31.0.13;
option time-offset -25200; 3600; # GMT + 1 hour;
option ntp-servers ip.address.of.myserver;# time server;
range dynamic-bootp ipaddressrange;

#Polycom phones here
group { # 1

See Polycom SIP Adminstrative guide (v2.0, page 7); boot-server option defined above option boot-server “tftp://polycom:[email protected]”;

#Now, list the phones by network address, to give them

defined IP per phone. Note that listing them here is

what makes them part of the group that gets the above

configuration

host x6681 { # host name is optional, but may help you track extensions
hardware ethernet 00:04:F2:E3:64:C7; # hardware address of phone - also serial number
fixed-address phoneipaddress; # IP you want assigned to the phone
};

list more phones here with their hardware address and IP address you want assigned.

host x6560 { # host name is optional, but may help you track extensions
hardware ethernet 00:04:F2:E3:66:11; # hardware address of phone - also serial number
fixed-address phoneipaddress; # IP you want assigned to the phone
};

}; #end of Polycom group

}; # end of subnet block

hi john,
I wanna use dhcpd for 4600 and 9600 avaya ip phones. what can I configure parameters like VLANid or call servport?
what do you recommend me??

Thax.

Hi Thax,

Thanks, sorry but I have not been very much on this lately. I got my VOIP installation working and have since just had it working without exploring much more into it. I never worked with avaya phones. Are they good?

John
