I recently upgraded an 11c with IP line card (VGMC) for 50 IP phones (i2050). We need to further upgrade for IP trunks (SIP ready) and I am wondering if I only need a Signalling Server or I also need in addition an IP Trunk Card (if so what type?). Does the Signalling Server also act as an IP trunk card, or do I need one media card to be configured for 32 IP trunks?
Thanks
George
