Siva, Is that the firmware the phones are running or the firmware they're trying to upgrade to?  You may be jumping too many versions at once. Brian ... View more

Mohammed, What firmware version are you running on your 9971s? Thanks, Brian ... View more

Ah okay.  So if you connect a PC to the 871, can you download files from your PC running TFTPd64 using a TFTP client?  Does a packet capture show any traffic at all from the phone to your PC running TFTP? ... View more

So the TFTPd64 is most likely the issue here.  How did you define the TFTP server option in TFTPd64?  As option 150 or 66?  Check out http://reboot.pro/topic/2048-tftpd32-with-cisco-phones-option-150/ ... View more

What type of connection do you have to the paging system?  FXO card?  FXS card? ... View more

Are you sure the phone is actually getting the TFTP server settings?  What are you using for handing out DHCP to the phone?  If you're using something like Tftpd64/32 for DHCP, the option 150 doesn't work right in there and you have to use Option 66. ... View more

So with sureshsub2's commands, you also need to configure another DN with the same number like this: ephone-dn  83  dual-line number 17772882353 no-reg primary label 17772882353 description Callcentric SIP Trunk Public preference 1 Then add DN 83 as an overlay on the same button as 82. With dual-lines, the phone that answers the first call has exclusive access to the 2nd channel for transferring/conferencing/etc.  We use the "no huntstop command" to allow the system to hunt to another DN is that one has all the channels used up.  By using "huntstop channel" on DN 82, we tell it to mark that DN down for incoming calls once the first channel is being used.  This still allows the first phone that answered to use the 2nd channel for outgoing calls/transfers/conferencing but it will hunt to the next matching DN for incoming calls to that number. ...

A quick google search shows a few companies that sell the scripts to do this.  If you want to make it on your own and have a good amount of programming background, you can view details about the IP Phone Services SDK at http://www.cisco.com/en/US/prod/collateral/voicesw/ps6788/phones/ps379/product_data_sheet09186a00800925a8.html. Once you have the script working, you just point the phones to it by adding a phone service and enabling Enterprise Subscription or manually associating phones to the service. ... View more

You still need some sort of web server to serve out the XML file that points to the RSS feeds. ... View more

Just wanted to update everyone on here with the details I found in the traces.  CUCM was doing Early Offer to the Nortel side and the 200OK from Nortel still had 2 codecs listed rather than one causing CUCM to immediately Re-Invite with G./711ulaw only.  It looks like the Nortel system doesn't know how to handle inbound early offer.  Solution will be to turn off Early Offer on the CUCM SIP Profile. ...

Andrew, So the issue here is CUCM and the Nortel system are both trying to Re-invite at the exact same time.  If you have SDI/SDL traces, I could take a look at what is triggering the Re-invite on the CUCM side. Brian ... View more
