 Posted: Mon Jun 09, 2008 2:29 pm Post subject: [asterisk-users] Polycom SIP and DHCP problem |
 |
|
Apologies - I know this isn't either Polycom or ISC support, but if
anyone would have an answer to my problem, I'm certain they would be on
this list.
I'm experiencing odd behavior with Polycom handsets obtaining DHCP
addresses. It always worked fine for me up until a few months ago.
Unfortunately, I can't narrow down when it stopped working, or why. All
my Polycoms now appear to ignore my DHCP server entirely, according to
the following pattern:
Polycom -> DHCPDISCOVER
Server -> DHCPOFFER on the correct network
Polycom -> DHCPREQUEST on the wrong network
Server -> DHCPNAK
Polycom -> Rinse, repeat ad infinitum
Here's some dumps of the DHCP packets:

Had the same issue a year or so ago - it related to a code version on
the Polycoms. We wiped the flash and let them reload software I
think. dont think we changed code but that took care of the issue.
This was on one of our IP430 installs, never had it happen with 6xx
series - yet. |

Unfortunately, I've tried that... I now have various BootROM versions
and multiple SIP versions - 1.6.x, 2.2.x, 3.0.0, 3.0.2c, on IP/301
IP/501 and IP/330 phones, all experiencing the same trouble. I've also
now tried different ISC DHCPd versions, on different platforms, and have
also tried W2k3's DHCP service.
I will believe it's a code problem - I see that the phones are picking
up *some* of the attributes I pass in DHCP offers, like the domain
name. Not only that, but I've sniffed a phone actually trying to ARP
the address the server DHCPOFFERED to it, before it decides to use a
192.168.0.x address.
Can you tell me exactly which versions you have working? |

This is probably a stupid suggestion, but nevertheless. You have
authoritative;
in your dhcpd.conf, right?

Just a suggestion, will defining a special VLAN just for the Polycom phone be able to get rid of such potential problems? |
