Addpac and Asterisk

Hi, I’m trying to configure an AP200(addpac) with asterisk, but only function one port. Example

AP200 has 1FXS and 1FXO, and I only can register one channel. Anybody has an example of sip.conf?

Tha problem is that addpac only use one username and password, and the channel number of the addpac must be the same that username, in order funtion well. But I Ihave two channels, I can’t use the same username and the same channel number.

Please help!!
