As reported at GigaOm this weekend, apparently Nokia has dropped support for its VoIP applications on some new N series products going forward. What appears to have happened is that some, but not all, of Nokia’s embedded SIP/VoIP stack has been removed. Some view this as an opportunity for more third party VoIP developers to jump in and innovate. Others view this as Nokia capitulating to the demands of mobile operators who see third-party VoIP apps cannibalizing high-margin international voice traffic.
Regardless, it re-opens the discussion about Nokia supporting a UMA client in the N and potentially E series devices. Nokia is the largest supplier of Wi-Fi-enabled devices today, and the lack of support for UMA in their N series products continues to be puzzling.
Capabilities such as ‘internet offload’, a dynamic routing capability in the handset which sends (for example) GSM voice traffic through the UMA tunnel but routes third party SIP/VoIP traffic directly to the internet, make it even easier for Nokia to support UMA and SIP/VoIP concurrently.
