I am trying to configure my Linksys Phone adpter (model SPA2102-R) with an ADSL modem supplied by my ISP, which is UTStarcom (model UT300R2U). Here's how I have connected them:

Wall Phone socket -> ADSL Modem -> Linksys Phone Adapter -> PC

The Internet is working fine thru this connection but not the Phone Adapter.

The connection type is PPPoE with the login details configured into the modem.

The IP set in the modem is Dymamic and so is in the Phone adapter.

Can anyone help me with this issue?
