so i've been toying around with voip again, and found it kind of useful, mostly cos i can have phone calls straight to my cellphone over wifi which i tend to have on me.  but i also have a standalone voip phone too.

so after my cellphone battery went dead, and i get an email saying there was voice mail, i decided to setup a pabx for home.

after screwing around for a bit i manage to figure out dialplans to let me choose to make calls through open vfx (free local calling) or 2talk plus (prepay) i realise that i can have redundancy for outgoing calling (as long as i top up 2talk every now and then).

then i'm thinking, i have no incoming redundancy, and i'm dependent on my net connection.  well, there's actually another net connection here, which with a wireless card i could fallback on.  but it appears open vfx doesn't mention anything about multiple registrations at once, and while screwing around with the pabx, and trying to have both on at once, i kind of just switched the 2talk over.

i also appear to get voice mail when i call myself on open vfx.  whereas 2talk seems to let me call myself to test my incoming ringing is working.

so i seem to have two options here, i could do number divert to ptsn, but then what if i want to make ptsn be forwarded through to the pabx, and i can't detect if it's a diverted number or not?  or i can get another sip number for open vfx and divert on that, and then do a double registration one against the wireless connection?

but then on the wireless connection how do i make it less preferrable?  and do i have to waste a registration/number on openvfx?

what are other people doing for fail over?  i've read about orcon having reoccuring issues with their voip service, and although i'm not using orcon for voip, i'm still slightly uneasy about the idea of calls being dropped.  i'd probably be ok if i knew who rang me - but it appears that i get emails for voice mails but not for missed calls?  both my cellphone and desktop phone will list missed calls... but only if it gets through to them.

and then what if the pabx goes down?  it's only running on a virtual machine on a pc, it doesn't have redundant power supplies, or ups, but tbh i wouldn't want the noise associated with such. would i be wiser just to have the whole pabx setup external and stick some small (silent? can you get silent?) ups on my adsl modem?

also i noticed that vfx didn't like one cellphone number which was stored in my cellphone in a +6421 format... i don't know if stripping it out on the pabx would help, or if it just doesn't like the destination.. it worked fine on 2talk.. but i've had occasional issues with being able to call people that use voip before,  but i don't know any nice way to force a call through one or the other without doing double registrations from my cellphone?

atm i have prefix of 4 or 5 to select.. but that wouldn't help when it's a call i received or from a sms?

i don't know if it's possible to detect it's not working and reroute it?

I use the VFX call forwarding not reachable function. Directs to my mobile if my VFX connection via a WRP400 is offline.

SIP can't have multiple registrations. Whichever endpoint has registered last will receive the inbound call.

+ signs also typically aren't used in SIP, if you're using E.164 format this will typically always be with the + stripped from the front.

It's slightly different usernames.

Yeah, I wouldn't think to dial a plus myself.  I had enough problems on my cellphone pushing # after putting my number in... force of habit? -- on my cell it does something weird, cellphones do special stuff with #'s... on my linksys phone with a 9 length, 7 length , 3 length, 0..(any length) dial plan -- it quickens up the calls.  i suppose it's probably safe to have 03 through 09 with 7 digits afterwrads...    but cellphone numbers don't seem to have defined lengths.

I've read this 3 times and I think I understand. You have invested huge time and effort trying to devise a system to overcome the problem of missing a call because your cellphone battery went flat. I may be missing something here, but wouldn't it be a whole lot easier to get into the habit of keeping your cellphone charged up? Apologies in advance if I have misunderstood.

Seriously dude, since when has learning about something new and gaining experience been a bad thing? I'm sure the world would be a crappier place if that was the attitude everyone had.

On the other hand, if you're just having a laugh, hur.

I do normally - my cellphone battery drains pretty fast with the sip client, and dodgy reception.

Sure - it would be nice to have a cellphone that lasted longer, but I think you're overestimating how much time and effort it took to setup pabx - and it was something I'd been meaning to do anyway.  One other thing I've found is that call quality is actually quite a bit better with the linksys phone.

I probably am a bit more prepared for such things than most home users.  I already had a computer running virtual machines, so I just had to clone a Linux install, configure an IP, install some packages, and do some configuration.  It probably would have been slightly quicker if I didn't ponder using NetBSD though.

Actually you have a number of options for incoming,

You will have Call Notify as one of your services
The Call Notify service allows you to receive an e-mail notification of calls from specified phone numbers, on specified days, and at specified times. The notification is delivered to you in the form of an e-mail message and includes the number from which the call came, the date, and the time of the call.

*** Note you will get this even if your offline for any issue****

Call Forwarding Not Reachable
Call Forwarding Not Reachable allows you to forward all your incoming calls to a different phone number when your device is not accessible.

Yes the +64 will not be valid so yes you would have trouble if your dialling this
