Benefit from on-net VoIP based audio conferencing services that eliminate toll free access charges when conducting audio conferencing sessions.

Global Crossing SIP Refer
Global Crossing offers customers with SIP-trunks the ability to blind transfer (without operator assistance) an inbound call to another location using the SIP Refer method (as defined in the IETF's RFC 3515). Once the Refer is accomplished, the customer's equipment is no longer involved in the call. As a result, the Simultaneous session usage is freed up to handle another call. This represents significant savings for customers doing frequent transfers.
