asterisk users - Aug 2009 - Anyone had any luck with SIP clients on the iPhone platform?

Hi,

I've tried two SIP clients so far and both have unusable outgoing
audio quality. Skype app sounds fine, and recording the same mic
sounds fine, so I can only assume there is an issue with the clients
themselves.

Both clients allow you to register and make calls via SIP with any
abitrary provider and credentials, so they'll work with Asterisk. I've
tried them with two good providers and one has unrecognizable audio
and the other has noises as if the cable was badly soldered. I've
never experienced such troubles with "regular" SIP clients.

Anyone have any recommendations?

Thanks

Which generation of the handset are you using?  They differ in their 
processing power and that may account for at least some of it.

For example, I had a first-generation EDGE iPhone and tried SIP clients 
over wifi and couldn't get anything useful out of them either.  I'm yet 
to attempt it again with the since-upgraded 3G version but suspect the 
results might be better.  It's hard to say, though.

As for VoIP over 3G, well, AT&T's 3G + the iPhone's inherent
flakyness
is so bad down here in LATA 438 as a combination that I don't see that 
happening, even though I've seen folks pull it off with cheerful success 
on Sprint and T-Mobile 3G via tether.

I made few test with various client, Sip and IAX, on iPhone first 
generation:

. frings: good quality but to much delay. Also I don't like the fact 
that it's Frings server which register to Asteris, not the client. 
Question of privacy
. iSip: good quality but also delay
. siax: same as above, even better quality than iSip, but still delay, 
doesn't matter Sip or IAX
. Weephone: perfect, good sound no delay.

All those tests where made from one location to the same Asterisk server 
somewhere on Internet. Also I didn't pay attention on the look or if you 
can connect few accounts.

Anyway, no one of those clients have the quality of a Nokia SIP client. 
To notice: when always WifI connected, the iPhone start to be hot, not 
cool when you're always on the phone ;-)
