Linphone has a free Android client (on the app store) and provides a free sip service. Depending on the codec, bandwidth is between 20-100Kbps (from memory). My maths is probably incorrect but 2GB of data should give you more than 200 hours of talk time on a low bandwidth codec. I had linphone on my android for a while and it worked ok but I had the usual SIP behind firewalls problem when trying to use it over wifi so that is something to be aware of. Anyway, you can find more info on their website of course: http://www.linphone.org/ I would be interested to hear how you go with it as I didn't really have anyone to call via SIP so uninstalled it in the end. Asterisk is fairly easy to install, configuration and security can be another issue, especially once you start dealing with firewalls and routers. SIP can be a finicky protocol (IMHO). I'd just go for using the free linphone service personally. Speaking of SIP services, does anyone know of any providers of federation or interconnection between SIP providers? It seems like most SIP providers still don't want to talk to each other. - Lauchlin ----- "It is a mistake to think you can solve any major problems just with potatoes."

I'm looking for free VOIP options for Android phones.
Google Hangouts has free video calls but it seems that the ring time usually isn't as long as the time taken to establish a connection so the caller often has it ring out before the recipient is notified of a call attempt.
Skype seems to demand a Hotmail/Microsoft account before it can be used.

Pennytel says that they aren't currently accepting new signups. When they do they apparently allow free calls to other users of the same service.

VoipBuster also apparently allows free calls to other users.
My aim is to have free calls to relatives who have Android phones. Many of my relatives are using Aldi with the $15 for 2G plan, so they pay for calls but 2G of data is way more than most of them will use in a month - essentially the marginal cost of data is zero.
How difficult is it to install Asterisk nowadays? Also how much bandwidth is required for two Asterisk clients talking to each other?
