We have been testing the Mitel ICS 7000 IP PBX in our office using SIP\nsoftphone and hardphones. Right now the Mitel box communicates with a\nMediatrix 1204 FXO gateway to the PSTN. I would like to find out what\noptions I have for adding a 8 port FXS gateway such as for connecting\nto a service provider like Vonage. I understand that Cisco 2600 has\n4FXO/8FXS network modules. What I really don't understand is how the\nwhole architecture of this thing is supposed to look like. Does anyone\nhave any experience in this field?\nThanks you.
