[Asterisk-Users] sip router gateway

[Anand S. Katti]

Hello All,

This is my first post to this list, I hope i'll get my problem solved
here.

I was using following set of software for my network within the LAN.
linphone[as SIP UA],partysip[SIP PROXY SERVER],GNUosip[SIP STACK]. with
ALSA SOUND DRIVERS.

Then I wanted to make IP-PSTN and PSTN-IP calls, so that i thought of
using siprg[a sip router gateway] using QUICKNET CTI LINE JACK CARD. But
unfortunately the card is available for ISA slots only. Where as I needed
PCI card.

Then after reading LINUX JOURNAL [ FEB edition 2004], i came across a nice
article by BRETT SCHWARZ on ASTERISK.

My question:

CAN I use asterisk software as a replacement for siprg ? CAN I use DIGIUMs
x100p PCI card as a replacement for QUICKNETS CTI LINE JACK CARD ?

CAN ASTERISK work as SIP ROUTER GATEWAY ?

CAN I USE ASTERISK, DIGIUMs card along with LINPHONE, PARTYSIP and
GNUoSIP. ?

Kindly put light on this.

Regards,
Anand
