Is there a way to get Polycom Kirk Wireless 4020 stations to work on a Telrad iPex2 v3.13/TVSe+ v3.48? We have some Polycom SoundStation2W station working just fine as analog phones connected to an SLD card. Is there a way to get the Kirk 4020 to do the same? If so, is there a specific Polycom base station that needs to be used? It looks like the entry-level Polycom Kirk Wireless Server 300 (KWS300) is SIP connection to the PBX, which would not work with our system I believe. Any guidance is appreciated.
