Rhino Analog card config help when connected to analog line.

[alloptic]

Hi

I have configured one R2T1 (PCI) cards and one RCB8FXX (PCI) card on the asterisk server with Trixbox. I am able to configured the R2T1 card and its channels as required. I can male call from SIP extension to extension configured for channel on the R2T1 card. Now for analog card, I have 2 fxo and 2 fxs channels. Channel 1 and 2 are FXO (which shows as FXS when I type ztcfg –vvv command I have below output for four channels of analog cards. I have configured 2 exgtensions for channels (51 and 52) which are shown as FXO below (aka, it has to connected to FX0). Two extension connected to channels 51 and 52 are working okay with the extensions I have configured with SIP. Now my problem is, how do I configure extensions for channels 49 and 50 which are connected to my company analog line.

Channel 49: FXS Kewlstart (Default) (Slaves: 49)
Channel 50: FXS Kewlstart (Default) (Slaves: 50)
Channel 51: FXO Loopstart (Default) (Slaves: 51)
Channel 52: FXO Loopstart (Default) (Slaves: 52)

My goal to configure two channels which are connected to my company analog line. Any call I make from SIP or R2T1 channel should go out from that analog lines if the dialed number is not one of the extension configured under my asterisk. I have connected a phone to the analog line I have. I am able to make call out side my company using 9 – 1-10 digit number for USA or Canada.

Any help is greatly appreciated. I am not a pro in Linux or telephony. So lil explanation like commands or reason will help me a lot.

Thanks
