After listening in on ABI Research’s recent talk on fixed-mobile convergence, analyst Stuart Carlaw has speculated that RIM will be providing SIP support in addition to its already-established UMA for the BlackBerry 8820. There was some concern earlier that the voice hand-off technology that the BlackBerry 8820 was touting (UMA) wouldn’t be compatible with the enterprise standard (SIP). ABI said that ever since acquiring Cingular, AT&T has been drifting towards SIP and similarly, RIM’s acquisition of Ascendent should facilitate PBX integration through SIP.
If AT&T’s release of the BlackBerry 8820 really is just around the corner, we’ll be finding out what it’s packing soon enough. Stuart also set UMA and SIP in a consumer versus enterprise light. If future Wi-Fi enabled BlackBerrys don’t work with both UMA and SIP, at very least we can hope that consumer-oriented products like the BlackBerry 8320 are packing UMA, and business-end products like the 8820 will be kicking SIP (even if it should have been there in the first place).
