Don't risk buying one unless you check first.. and some of the
phones that ship have SIP firmware on them that doesn't work
with * for me.
There are a lot of phones coming out of China now that are being
rebranded under a lot of different names ( but are all really the same
If you end up with the PA168x series chipsets, then you may be able
find an IAX2 firmware for the phone that you can use instead of SIP
for direct connections to *
We have a couple of the Siptronic ST-150's (siptronic.com )
that we use in the office here, and the phones themselves are fine.
Siptronic ship an older version of the firmware ( v1.42 ) than you
can get from the home site of the manufacturer ( www.aredfox.com )
but as it's all the same chipset - firmware sources don't seem to matter much.
In terms of the phones themselves - the cord from phone to handset
is a little shorter than we're used to - but that should extend with use.
There are loads of extra buttons on the phones, but most of them have
little to do with making calls ( you get a whole button to read out
your configured IP address, and another one for your server IP address )
which seems like a waste of buttons.
SIP phones tend to try do lots of stuff on the phone, whereas a traditional
phone tends to do stuff at the PBX level - so you'll end up with things
like - hold music configured on the * server, but the hold button on the
phone does a local hold of the call.
There are IAX2 firmware releases available for the PA168x chipset phones
so we have some phones configured as SIP and some as IAX2.. the only
noticable difference is MWI notification works for SIP but not for IAX2
If you are after the siptronic phones, then you can get them direct from
siptronic via Ebay - they go for about EUR 80 (plus p&p ), ship from germany
arrive without delay.
