Hi - I've been trying to set up my Polycom phones to get the boot server info (tftp-server-address) from DHCP on a Cisco router. I've previously just specified it manually on the phone, and that works well enough, but I need to change now (because of the number and geographic locations of the phones). I can actually get it to work just fine (using option 66 on the Cisco router), if I change the DHCP menu on the Polycom phone to show "BootSrv Type: String". That's great, but that's not a default setting, and I don't want to have to change any settings on the phone. I want the phones to be able to provision fully, out-of-the-box, with nothing but the info from DHCP. If I leave the default setting (BootSrv Type: IP Address), and tell the Cisco router to send the boot serverinfo as an IP rather than as a string, nothing happens. The phone just says "Could not contact boot server, using existing configuration", but according to the FTP logs and ethereal, the phone doesn't actually try to contact the boot server at all. I've tried various version of the bootrom, but nothing has worked so far. Has anybody gotten this to work? (Cisco router DHCP and Polycom boot server) Thanks, Noah
When you set up the DHCP pool in Cisco you need to use syntax like: --> option 66 ascii "a.b.c.d" Peter> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com > [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of > Noah Miller > Sent: Thursday, 10 November 2005 9:08 AM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: [Asterisk-Users] Cisco DHCP and Polycom boot server > > Hi - > > I've been trying to set up my Polycom phones to get the boot > server info > (tftp-server-address) from DHCP on a Cisco router.

(Cisco router DHCP and Polycom boot server)If you want this to be anywhere near reliable, then consider switching from tftp to ftp per the Polycom warnings. The phones "want" to check the timestamps of various files to determine whether to read/implement that file, and tftp does not support that. You might get it to work the first time, but subsequent changes to those files will not be read by the phone.
Hi Peter -> When you set up the DHCP pool in Cisco you need to use syntax like: > > --> option 66 ascii "a.b.c.d"Thanks! I guess maybe I didn't explain very well. I did get this far, and this seems to work well, if I manually set the phone to read an ascii string. I'm being really picky here, though. I want Joe Schmoe user to be able to plug in the phone and have it get provisioned without having to make any changes to the phone (like selecting to use a DCHP string rather than an IP). With all the Cisco phones that I have, the default setting has been to read the tftp-boot-server parameter as an IP rather than as a string, and I can't get this to work with Cisco DHCP. Maybe somebody else has, though?
