One of our customer has an UC520 system with SWP 7.0.2. They want to use new SPA303 phone but this version of sw does not support this type of phone.
I read in the document of “UC 500 Software Packs” (https://supportforums.cisco.com/docs/DOC-9827) that the SWP 7.0.4 supports the SPA30x type Phones.
Unfortunately I do not find the SWP 7.0.4 on CCO.
How can I upgrade the UC520 to SWP 7.0.4 in order to use the new SAP303 type phones with the UC520 of our customer?
I have also asked this from firstname.lastname@example.org but they do not anwser me.
Thank you for any help in advance,
