SIP software on PDA/XDA?
|
|
|
| Sorry if this has been asked before, but I cant find an answer for it..
I am in the process of buying a PDA, mainly for Sat Nav in the car, but
I thought I might aswell buy one with WiFi when I first buy.. And with
WiFi I would like to be able to make/recieve phonecalls on it aswell if
possible, when connected to a WiFi point. So, does anybody have any
experience with PDAs and SIP software? I understand X-lite make one,
but im not sure if it works properly.
| |
|
| I would also be interested in how the speaker works.. Can you actually
use the PDA as a phone, wont the speaker give a echo for the caller? Or
would you use a headset, etc?

| Hi,
We are in the process of developing a SIP phone for a Palm PDAs and
there is one already available (mobiVoip). Ours should be available in
the next couple of months.
You could use a headset to prevent echo, alternatively most software
should have echo cancellation to prevent echo when the PDA is used as a
speakerphone.

SJ Phone is a good one

Just out of interest, do most [whatever that means] PDAs have enough
horsepower to do echo cancellation?

Having used both SJ Phone and X-Lite with an iPAQ 4155, I'd say that SJ
Phone is marginally better in terms of ease of use and X-Lite is better
in terms of functionality, has slightly better sound quality but is a
bugger to configure.
Overall, SIP softphones on a PDA give 'OK' sound quality, but I'd not
want to use them as my main phone.
They're both free apps so why not give them both a test run?

If that's all you are buying it for, don't.
A standalone unit that's purpose-designed is a better bet, as long as
you don't buy the cheapest on the market.

| Yes. Simple echo cancellation takes no where near the power required
for the voice compression and this works without any problems on a
modern PDA.
Many PDAs have processors that are faster than desktop PCs of not so
many years ago! PDA speed is often more limited by factors other than
the processor horsepower (e.g. flash memory, battery preservation etc.).

I need a PDA for organising numbers/addresses/birthdays, etc aswell, so
instead of getting a simple PDA to replace my broken Palm top I'll get
something I can use for both.. The WiFi/VoIP is just an added bonus
which allows me to use the unit for even more.

Fair enough.
There is very little VOIP software for WM5, just a beta of SJPhone,
AFAIK. Unless you get WM5 in the PDA, you'll probably lose all your
numbers/addresses/birthdays when the battery runs down, so I'd suggest
that WM5 is required.

I have an XDA Exec running Windows Mobile 5.
Neither X-Lite nor [WM5 beta] SJphone would even start for me. There are a
couple of other SIP clients but they are targetted at the ISP/Corporate
appliance markets. I await a working SIP client with great anticipation.

The WM5 SJPhone is fine for me on an HX4700, but for the fact that the
link to answer an incoming call refuses to work. Instead, I mapped a
hardware button to answer, and it is just fine.
