Hi, I have a customer who want to use existing Cisco phones on an Alcatel IP-PABX. In order to use these Cisco IP phones on, they would need to be converted to SIP mode. I have the phone models and the current firmware attached. Can you confirm if the current firmware is ready to support SIP mode or does the customer need to download the Cisco SIP firmware for each handset? Thank you

cisco would not support this setup, but if you want to put SIP loads on exiting phones, you would need to use TFTP by means of option 150, so you would need to host a tftp server with the alcatel required loads on them. Personally I wouldnt even go there, you will never be able to run the phones to the max of their capabilities

it's a few hundred phones actually. i thought an upgrade of firmware to SIP for models that support it would be good enough?
