Can two Linksys WRT310n routers be linked as wireless access points?

My VoIP network has a Linksys WRT310n hooked in between one of the phones and a computer. It is set up as a wireless access point as well (by using the regular ethernet ports – NOT the internet port). I need wireless access farther away in the building (a church). Is there anyway I can add another WRT310n wired out of the regular ethernet ports. Normally, I’d just get a new wireless access point, but I have an extra WRT310n on hand. Thanks in advance.
