@LeShuttle I exchanged my booking for a voucher over the phone, but just got an email confirming my original booking... What should I do?

[Mark Grayson @markg_cisco]

@LeShuttle constantly getting cut off after initial message - any indication when your telephone system will be back operating?

[Mark Grayson @markg_cisco]

@disruptivedean @TXingh sorry - should have read "in its DNSROAM mode"... an

[Mark Grayson @markg_cisco]

@disruptivedean @TXingh think eduroam in its PKI/RADSEC mode, but with a cloud CA, that then supports the widest range of identity providers, including those that require their users to remain anonymous and those whose terms of service allow them to signal public identities

[Mark Grayson @markg_cisco]

@disruptivedean Totally Agree. #WiFi is already serving the "vertical markets" that #5G has aspirations to serve. Importantly, the vertical value chains are very different from the coverage/capacity horizontal value proposition used to support conventional consumer-centric cellular propositions.

@jsnyder81 no docs - but take a look at https://t.co/WPDSDjh4ha where Jerome discusses call flows between access and identity providers

[Mark Grayson @markg_cisco]

@disruptivedean Hi @disruptivedean - take a look at https://t.co/VppnwcuDjx - an initiative announced today to make Wi-Fi as seamless to use as cellular, not just in Carrier Wi-Fi deployments, but all vertical environments.

@keithdyer @elenaneira @CiscoSP360 Looking at other PNF/VNF splits, there is DOCSIS R-PHY. Note also that nFAPI uses a neutral host management model for sharing use cases.

@disruptivedean and slightly less that 118% growth in per-SIM data observed by Ofcom in the UK over last 12 months http://t.co/h6Ue4EiM

@CiscoSPMobility Bring on data meter app for iOS!
mydatamanager is showing >90% of my iPhone traffic doesn't touch a cellular network.

[Mark Grayson @markg_cisco]

@CiscoSPMobility Cisco's latest WLC release certainly supports SP requirements: http://t.co/b9mPlqx1. HA and up to 40K PMIPv6 users!

@CiscoSPMobility: Wi-Fi is just another small cell technology and can be integrated into MNO architetures: http://t.co/0K2N95Oz

@stewartbaines if you get charged a wholesale rate of 6cents/MB then it certainly is a "no brainer" #FWS11

[Mark Grayson @markg_cisco]

@Femto_Forum - The economics of MVNO/wholesale and/or New Entrant/National roaming drive such operators to define an offload strategy #fws11

#ciscospchat Thanks for some great tweets. See you next time.

[Mark Grayson @markg_cisco]

@rgruia @kshatzka : so would say that they are in play, but you need legacy support 2G/3G/4G -> GW and Control (IMO). #ciscospchat

[Mark Grayson @markg_cisco]

@kshatzka @rgruia : that is a price to the consumer - not the carrier ASP. Still our ABI analysis looked at both models. #ciscospchat

@Teresacottam Right - NOK/MSFT is a H/W-S/W tie up when everyone else is talking ecosystems. #ciscospchat
