What is the name and structure of the Teltronics CIP210 ip settings file?

Question

SIP

Several Teltronics CIP210 ip phones were found in the warehouse - the idea arose to connect them to the sip / h323 server of the enterprise (Yate).
On the phone interface, sip or other ip telephony protocol is not configured, but the ip of the server from which the configuration file can be retrieved is indicated (by analogy with "ciscophones"). The phone searches for the settings file (possibly firmware too) using the tftp, ftp, http protocols, but I don’t know the format of the file itself and even its name. Attempts to search for documentation yielded no results: all possible links lead to the old teltronics website http://www.teltronics.com (namely http://www.teltronics.com/download/community/download/20050909_141106_14302.pdf ). On the new website of the company http://medtelservices.com/already "not a word, not half a word" about this phone.
In which direction should you dig on this piece of iron?
