Android sip softphone

Has anyone experience of using any of the sip softphones (such as
sipdroid) for the android operating system.

I'm thinking in terms of a data only contract on one of the new android
tablet devices. I know the data service provider might want to block sip
traffic, but would it be OK on wi-fi from a hotspot where one had
access?

I've read quite a bit about the Skype client for android, but my
interest is for incoming calls to an established number that was
recently ported to voipfone.

I've no experience with Andriod, but I do use a Nokia N900 with it's
built-in SIP software.

If using 3G, then you obviously need to be in a 3G enabled location
for the network you're with... I don't think any currently block VoIP -
at least O2 (who I'm with) don't seem to....

Wi-Fi is fine too - but Wi-Fi is rubbish for VoIP - unless it's very
carefully controlled. On public access points you might "get away" with
it, but do not rely on it. It's trivially easy for another user of the
same access point to saturate the link to the extent that voice quality
will be unusable.

But they do prohibit it in their T&C (unless you pay for the industrial £25
pcm bolt on) so watch out.

Voip over 3G can be very jumpy and inbound calls often miss.

I find Wi-fi excellent for Voip (on an N79) - check your settings.

I agree with Gordon. Voip over WiFi on my N95 8GB is excellent. Over 3G
though I have found it to be very poor.
I think that my next phone will have the Android OS. The concern I have
re voip clients is that some are reportedly heavy on battery use. The
Nokia client on the N95 seems to be OK. For me a suitable SIP voip client
and wifi are essential features. When I got the N95 there wasn't a
suitable touch screen phone on the market. So I'd be interested to hear
of any performance reports on Android SIP voip clients.My next phone has
to have a bright, better technology, screen, be touchscreen, have all the
features of the N95 and be freely customisable.
btw. Can someone invent an 'iPhone/iPad/Apple/Steve Jobs' filter - sick
of hearing about them!!

I rarely use VoIp while in 3G coverage - I have a mobiel phone for that.

>Voip over 3G can be very jumpy and inbound calls often miss.

Indeed. I did have a client use a 3D dongle off a router for VoIp for a
few months until they moved and got ADSL. Forgot to ask him what network
though, but he seemed happy with it.

My settings are fine. It works fine, but it's trivially easy to stop it
working. Wi-Fi is not a good carrier medium for VoIP unless it's very
carefully controlled, so in-general, it's rubbish for VoIP because it's
trivially easy for one user doing downloads or uploads to disrupt VoIP.

Not available yet and likely to be expensive, but
