Galaxy S II vs Galaxy Nexus
Hi Guys, Here is the comparison of the devices: http://www.gsmarena.com/compare.php3?idPhone1=3621&idPhone2=4219 The screen resolution was updated for the Nexus since last time I did the comparison..... The Nexus has no slot for a microSD card. The S II has better cameras (front and back). The battery life is also quite different, but the figures could be wrong.... Anyway, see the comparison at the above link. The Galaxy S III should be nice when it arrives, in the meantime, we are getting the Galaxy Note this month, another consideration ;-) -- Kind Regards AndrewM Andrew McGlashan Broadband Solutions now including VoIP Current Land Line No: 03 9012 2102 Mobile: 04 2574 1827 Fax: 03 9012 2178 National No: 1300 85 3804 Affinity Vision Australia Pty Ltd http://www.affinityvision.com.au http://adsl2choice.net.au In Case of Emergency -- http://www.affinityvision.com.au/ice.html

Diverging slightly from the subject of Android phone hardware; I was sitting around with a friend complaining about the absence of an 'answering machine' function; of any of the phones in an advertising catalog. The conclusion we came to was, that it was because phone companies make so much money, from voice-mail, that they are motivated to discourage manufacturers, from such an innovation.But then it occurred that the obvious way to 'break the monopoly', was for someone to write an 'answering machine ap' . Obviously Android would be the ideal target OS so: 1/ Can it be done ? 2/Has it been done ? regards Rohan McLeod

I run FreeSWITCH, which has a voicemail application included (as does Asterisk). If I don't answer a SIP call within a specified time (I think I've set it to 30 seconds), the voicemail application is invoked, a message is recorded, then sendmail (really Postfix in my installation) is run to send me a message, with the wave file as an attachment. My primary inbox is on the same machine as FreeSWITCH, so the wave file is never transferred over the network unless I log in from my laptop, read the message, transfer the file to the laptop and play it locally. It would be possible to link in a mobile phone to this scenario via SIP. I recall that there's some support for GSM devices also, but I can't remember the details. The disadvantage of having a voicemail application on the phone is that it won't be invoked when the device is switched off or otherwise inaccessible - the very moments in which it is most needed. If there's an API for the call handling, you should be able to write one, however. I have a very basic mobile phone at the moment which I use sparingly. If I were to buy a more sophisticated device, I would prefer just to invest in a data plan and use SIP. So far as I know, mobile networks aren't good for low-latency traffic and I understand that the carriers have revenue reasons to discourage it, but ideally it should be possible to use the phone simply as a SIP (or XMPP, if you prefer) endpoint.

I found them: http://wiki.freeswitch.org/wiki/GSMopen The only problem I can see in this arrangement is that if someone calls FreeSWITCH and the call is then transferred to my mobile phone via GSM, then (assuming that I'm the owner of the GSM device attached to the FreeSWITCH installation), I am charged for the second leg of the call.

That's reasonably easy fixed if you have a plan that allows free calls on-net [Exetel to Exetel for example] -- I also have a land line that gives unlimited local/national calls and also free to any Optus network mobile. Pity that Vodafone and Telstra phones aren't included, but knocking out Optus network mobiles from call costs is still pretty good. The land line plan requires a business service and can only by applied for by PTY LTD businesses; they deliberately exclude sole traders from these plans :( Cheers -- Kind Regards AndrewM Andrew McGlashan Broadband Solutions now including VoIP

I use sipsorcery with a free callcentric account to handle voicemail. SIP is good, but hardly ever so over a mobile network in AU -- I think that carriers deliberately add latency for this reason; that is to stop you using VoIP successfully and to bypass mobile calls as much as possible.

My experience on Three and Virgin (carried by Optus) is that they don't need to deliberately add latency. The latency for data operations is bad enough to make ssh difficult at times, far worse than anything that could be used for VOIP. It seems that if the carriers were trying to discourage certain uses of their network they would want to make it bad for VOIP but good for ssh and other data applications, but this isn't happening. Also periods of total IP outage are not uncommon with Virgin. VOIP really requires a reliable connection, having no data access for periods from 30 seconds to 30 minutes really makes it unusable. While 30 minute outages are rare 30 second outages aren't. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Okay, but Three has it's own network which has nothing to do with Optus whatsoever. Virgin does use Optus network though. Cheers AndrewM
