Ladislav: X-Ten calls that "hard coding" and the sell you licences. We contacted these guys last week and they say the minimun amount of X-Lites's that they sell are 27K units. So, if you are looking for GNU try using a sip stack such as oSIP to create your own app. Andres Parra __________________________________ Do you Yahoo!? Take Yahoo! Mail with you!
