It's been a while but I successfully set my Grandstream GXP-2000 up with gizmo5+GV (when gizmo was free) and Magic Jack (When there was a hack).

Just wait for shaggy to post, if he's kept up with everything he's the resident siphax guru. PAP2 +Asterix ran his entire phone system IIRC.

PAP2 + callcentric + google voice is what I go with for cheap international calls. gizmo quality sucks and the calls are limited 2 min. legit pap2's are hard to find. the one i ordered from newegg even was some gray market trash. ooma is probly the cheapest option for a sip provider at ~$3.50/month after the initial $120 on the box but at least you know it's a legit ATA for a decent price

you can use sipdroid and gvoice callback from the market for the time being. At least until the end of this year when Google stops allowing free outgoing calls.

I've setup 2 systems; but one used lines from an ooma hub, and the other digital lines straight from TWC. After both I've realized I want a system like that in my house. Direct calls for the kids to their room and never ring the whole house. I like it.

i already make all my calls free - my google voice number is on my fave 3 list on sprint but just trying to learn what this stuff is and if it's worth setting it up.

is it just a geeky way to get free calls?

Systems like Asterik offer a ton of features even when used with regular old phone lines. Block callers, automate answering for certain numbers, forward numbers, etc. Pretty much everything that made google voice popular (emailing text and mp3 messages) combined with custom phones - almost anything and everything you'd possible want or dream up has already been written into a free plugin.

Combine that system with an all digital solution like google voice, or cheap VOIP (ooma, magic jack, etc) and you've got quite a little system. I'm getting ready to move into a new apartment and I'll probably set it up with magic jack or ooma if they're on sale ran into one of those dell mini PC things with atom processors. They really just need to implement ooma or magic jack in software so we can finish this process and make it nice and clean looking.

i haven't looked at this in forever. It used to be that you could tie your google voice account to gizmo and then connect your sip client to gizmo. Any inbound calls would ring your gizmo phone along with your cellphone or whatever other phone like normal. You could also dial out via google voice over your gizmo phone for free. Effectively creating unlimited SIP calling for free (for anywhere thats free w/ google voice).

However, they shut down gizmo to registrations a while ago and it looks like they're terminating gizmo all together in april so that aint gonna work anymore.

Apparently if you dial sip:+1gvnumber@sip.voice.google.com (from whatever sip phone) google will take it. But thats really only useful if you're calling someone on google voice.

afaik you still cant use google directly as a sip proxy/server agent. idk if thats gonna change but i'm assuming its why they bought gizmo. you're pretty much sol for now.

^^MagiCall of the TP2+GV+Fav3 fame should be getting an android app soon if not already. I used to use the shit out of that myself on my SERO 500 plan. FWIW. I guess it doesn't matter anymore if GV is integrated cleanly, I haven't played around with it.

some notes about magic jack: they were legit when i used them. The only downside was that you needed to run their sip phone (a modified sjphone [iirc]) on your comp to get calls. Kind of lame, but for the price you cant really complain that much.

However, it used to be you could dig the SIP credentials out of the phone and then use them with any sip client. Meaning you could plug them into your ATA or Asterisk or xlite and do whatever you wanted with it. Then they eventually plugged that hole, so I stopped using them. idk if theres a new hack to get the sip info these days. it wouldn't be hard for them to create separate sip creds for each phone client launch which would effectively remove any possibility of getting good creds.

Also I'm pretty sure i remember reading they were losing money like mad but idk if that was true.

I figured I could just post here instead of bumping one of the older SIP threads.

Is anyone informed enough to explain the pros and cons of a PRI vs SIP trunking? FWIW, 23 lines would be plenty from now to the foreseeable future.

i use SIPgate and flowroute for my termination.

flowroute is awesome and cheap.
