Why wasn't the T.38 Protocol implemented on the Linksys WRTU54G-TM for fax? This router is pretty decent without the fax. I just wonder if there's no T.38 Protocol at Linksys WRTU54G-TM would there be better versions in the future or can it be implemented by a firmware. I wonder if a Linksys SPA-2102 can replaced the fax part if I attach it to Linksys WRTU54G-TM.
