Left: With a call placed, I could mute the line, put it through to the iPhone speakerphone, put the call on hold, transfer the call to
another PSTN extension or add another party to the call. Middle: After adding a second caller, I can see connection time for each
individual call, then merge them together via the Merge Calls button. Right: Line2 tracks previously called contacts to build a
roster of frequently called numbers. I could also switch to the contact tab to access the records in the iPhone contact database.
I did find the call quality of the Line2 VOIP line over
my office 802.11n WiFi network to be excellent, with no
noticeable distortions or jitter effects, nor any unusual
delay effects. iPhone users can also configure Line2 to
place VOIP calls over AT&T’s 3G data network, although
mileage may vary depending on the data coverage and
Once a VOIP call had been connected through the
Toktumi line, I could easily transfer the call to other
land or mobile lines, and I could also conference in
additional parties with just a few clicks.
I found Line2’s SMS messaging worked quite well, as I
was easily able to initiate conversations with mobile phones
in my contact directory. Like the iPhone, Line2 keeps a
threaded view of text conversations, tracking my recent
conversations and allowing me to easily drill back down
into prior conversations to see what was said and when.
MMS (Multimedia Messaging Service) is not cur-
rently supported, however, so Line2 can’t be used to
share pictures or videos.
For customers looking for a more robust, small business class VOIP offering that works across multiple
endpoint devices, Toktumi also offers an upgrade to
its full Toktumi Hosted PBX Phone Service. For $15 a
month (or $80 for five prepaid months), the full service
offers an auto attendant, conference calling, customized
greetings and visual voice mail, among other features. ´
doesn’t work as well as Toktumi’s and has per-message
costs associated with it.
Line2 offers iPhone, iPad or iPod Touch (
second-generation or better) users a full telephone line for their
device. For iPhone users, this acts as a complete second
line, with its own number (which the user chooses when
registering for Line2) that operates in parallel with the
native AT&T extension.
While the iPad is currently supported, expect Line2
to work better on that device once Apple lights up
background tasks on its slate in the forthcoming iOS
4.2 software release.
Dial from keypad or directory
When placing calls, users can dial numbers directly
from the Line2 on-screen keypad, or they can access
the iPhone’s contact directory through Line2. A toggle
button on the dial pad allows the user to select whether
to place the call via the AT&T line or the Toktumi line.
However, I tested Version 3.0.1 of Line2 using my
SIM-less iPhone 3GS (I had happily quit AT&T earlier
this year)—making my iPhone the equivalent of an iPad
or an iPod Touch. Consequently, I didn’t have access to
an AT&T line to try these features.
