Possibly compatible after changes.

Suggestions

Disable SIP ALG.

Comments

We recommend disabling SIP ALG through the DIR-625’s web interface. After the change, this router appears compatible and can serve up to three or four phones. Consumers who have tried to connect a larger number of phones to this router have found that the additional phones fail to register. It is not recommended that this router be used for a larger-scale deployment as it does not appear to perform reliably.
