[jitsi-users] Push to talk feature for Jitsi


#1

Hi All,

I would like to know if Push to talk feature is available for Jitsi?
Is there any other way to implement push-to-talk for Jitsi on client side?

Thanks & regards,
Rashmi


#2

Hey Rashmi,

Could you please tell us exactly what you mean by pust-to-talk?

Hi All,
is it possible to call with one SIP account (e.g IPTEL) to any other SIP
contact of my choice ( e.g. to an IPPI contact or SIP2SIP contact)
without owning an account with the other provider?

So far it looks that using SIP with Jitsi only calls between e.g.
IPTEL-IPTEL and IPPI-IPPI accounts are possible (at least Jitsi alerts
that I have to add the other account first before I am able to call...)
or am I missing something?

Q: is this a general feature of SIP (only accounts of same SIP provider
can call each other) or is it a restriction of Jitsi? (using XMPP with
Jitsi with one account at Gmail I can add any other XMPP contact of my
choice - GMX, jabber, web.de, jabber80 etcetc)

looking forward for encrypted videoconferencing and the android version
- very impressive progress !!!

kind regards MS

Emil,

I believe this is a feature that can be offered on GSM wireless telephone networks.

Similar to walkie-talkie operation.

I do not understand what this has to do with Jitsi.

Hi Emil,

Sorry for delay in replying your email. I hope the email below gives the
idea of Push-to-talk feature.

*About Push-to-talk(PTT):*
Push to talk feature is a method of conversing on half-duplex communication
lines using a momentary button to switch from voice reception mode to
transmit mode. Conventionally, the device used for PTT is a two-way radio
(transceiver). By default it is in Receiver mode. It is connected to other
transceivers which operate on the same radio frequency within particular
range. One can either talk or listen. For transmitting i.e. when one wants
to speak he/she needs to press and hold the PTT button. Once the button is
released it is switched back to receive mode.
Basically, Push to talk functinality is same as walkie-talkie.
It is used in air traffic controlling, Police radios etc.

*Push To Talk over Cellular (PoC): *This feature allows the users to turn
their cell phone into a walkie-talkie with a much wider range.These days
many cell phones do support this feature. There is a youtube video which
gives better idea on how PTT works
http://www.youtube.com/watch?v=aG_X756nHus

*What is that we are looking for from Jitsi?*
The PTT feature can be very much useful for voice conferencing.
PTT feature has below advantages :
1. A quick telephone conference with a group of people. Users need not make
several calls to coordinate with a group.
2. Participants don't have to answer the phone, as the speaker's voice is
automatically played through their phones' loudspeakers

*We would need PTT feature over IP.* I got the information from the net
that PTT uses IETF standardized Session Initiation Protocol *(SIP)* for IP
communications.

This feature is very helpful in group-chat or one-to-many chat.
On "Google+ hangout" Push-to-talk feature is available while watching
youtube videos.

Our requirement is similar. During voice conference there should be a
feature to enable PushToTalk. If is is enabled for the group only one
person should be able to speak at a time and others from the group can only
listen.

Since, Jitsi has voice conference and supports SIP protocol, I was
wondering if this feature is available or can be made available.

Please let me know if more clarification is needed from me.

Thanks & regards,
Rashmi

Hi Mr Smith,

Le 14/02/12 22:09, Mr.Smith a �crit :

Hi All,
is it possible to call with one SIP account (e.g IPTEL) to any other SIP
contact of my choice ( e.g. to an IPPI contact or SIP2SIP contact)
without owning an account with the other provider?

Yes it is possible. I usealy call SIP contacts that do not belongs to the same provider as me.

So far it looks that using SIP with Jitsi only calls between e.g.
IPTEL-IPTEL and IPPI-IPPI accounts are possible (at least Jitsi alerts
that I have to add the other account first before I am able to call...)
or am I missing something?

Are you sure it is SIP contact ? This case makes me think, it is an XMPP contact (which you have to add as contact prior to call it). Or maybe you try to call with a XMPP account rather than a SIP ones ?

Q: is this a general feature of SIP (only accounts of same SIP provider
can call each other) or is it a restriction of Jitsi? (using XMPP with
Jitsi with one account at Gmail I can add any other XMPP contact of my
choice - GMX, jabber, web.de, jabber80 etcetc)

looking forward for encrypted videoconferencing and the android version
- very impressive progress !!!

Thanks for your kind words!

Best regards,

Hey Rashmi,

We may, at some point implement the feature that has you muted by
default and unmutes only while pushing a button. Could you please open
an issue in our tracker for this case?

FYI, even though it's not quite like the real thing, you could actually
simulate something similar today with our Global Mute key shortcut.

As fot the Mobile PTT protocol, that's obviously out of scope for Jitsi.

Daniel mentioned support for multi-casting that might be somewhat
similar to the walkie-talkie broadcast use case but this would require a
lot of effort to get right and I don't think we will be implementing
anything like that in the foreseeable future.

Hope this helps,
Emil

Hey Rashmi,

Hi Emil,

We will check the Global Mute feature. Also, I have sent email to
jitsi-issues mailing list.

Well actually, tickets are opened on our issue tracker [0]. The issues
mailing list is only used for automated notifications from the tracker.

Cheers,
Emil
