Hi,
I'm using asterisk 1.14.19
I'm making a video call between two SIP end-points, using h263p and iLBC. I
notice the video is jumpy and I believe the cause is due to RTP timestamps.
The sending device is working at 8fps and correctly increases the timestamp
by 11250 every frame. It appears that
I need to dial a DTMF string with the Dial function using the D("DTMF")
function. What is the character for a delay? I mean, normally in other
technologies we use the comma to mean "wait 200 ms ". Is there an equivalent
in Asterisk? If it is the comma indeed, how many ms will the system wait for

I've used C-Band, Ku-Band, and DVB satellite internationally with VoIP
for years at a previous employer and rarely had any problems was the
sat link was up and running.
If you do plan on having 'remote offices', you'll want to make sure
they all come back to a central earth station (hub and
I've used VOIP over satellite for years and while it's not perfect it is
sometimes actually better than cellular voice
Unless you have a double hop scenario where the traffic makes two satellite
hops from one remote to a central hub and then to another satellite remote
the latency is actually not

This option tells the device how often to update the phone's VISUAL mail
waiting indicator. As in that icon or red flashing light
Is there anything already out there that can efficiently convert a
JSON string into Asterisk dialplan variables?
Our current backend speaks JSON and we need to parse the response to
construct the dialstring.

Hi people,
i'm writting because i would like to know is someone of you have field
experience on implementing 2-way radio systems with Asterisk:
* app_rpt: TIARA Technology [a.k.a. Asterisk/app_rpt project] is the
integration of 2-way radio systems and reasonable telephony
* chan_rtpdir: Asteris
Looks like an expensive way to do it - if power consumption is your
issue why not just go for one of the off the shelf asterisk appliance
solutions that are out there.
...of course this is my cue to recommend the Vdex-40
(http://www.taa.com/products-vdex-40.html) but seriously what advantages
are
I agree.
You will probably get good ping times between your sites in Asia, but if
your thinking about a back hall back to the states this is where your going
to have the latency issues crop up.

Hi, using Asterisk over satellite can be done. Not all satellite providers
are created equal and some are better than others.
If you are going to do communications between offices that are connected
over satellite office to office you may have a problem.
My personal choice for satellite connections

We're entertaining moving our intranet to Hughes satelite for our remote

if so, is the latency an issue. My understanding is that you immediately
introduce 250ms latency for travel time up and back down, however it

Dear All,
What setup would you recommend for making VoIP calls whilst bringing
latency down between offices at:
* Edinburgh
* Kuala Lumpur
* Singapore
* Tokyo
* Seoul
* Beijing
* San Francisco
Some of the Asia offices are > 300ms some > 200ms.
Any advice greatly apreciated.
Thanks.

If the Linksys unit is forced to a single specific DTMF type, and
Asterisk is set specifically to something other than the Linksys, then
when the Asterisk server answers the line your DTMF will not be
recognized. If your outbound termination vendor supports the Linksys'
DTMF settings, then
