[Asterisk-video] 3G-324M service provider

[Ramtin Amin]

the price of those appliance, I would say between $50.000 and $120.000 for 30 concurrent calls...
 
The way to connect it: 
 
Softphone (IP) <-----> Asterisk (IP) <---- > Radvision  <----> PRI< ---> (UMTS <----> 3G Cellphone)
 
So from the softphone to asterisk : SIP (audio + video)
from asterisk to Radvision: SIP (Audio + VIdeo)
>From Radvision to PRI: 3GPP-H324M over PRI or BRI
 
one call takes a single B-channel...

Hi,
 
1. How much could cost such appliances (Dilithium or Radvision) ?
I thought it could be difficult to build valuable business cases for SME with such appliances.
 
2. Do you think these appliances could easily integrate with Asterisk today ?
Reading this mailing list archive, I guess it is today possible to set things this way :
 
- Radvision appliance connects to Asterisk using one BRI or PRI port
- Asterisk connects to PSTN-ISDN using another BRI or PRI port (hoping TDM bridging works faultlessly)
- Radvision appliance and (soft or hard) SIP videophones register to Asterisk and belong to the same LAN
- for outgoing video calls (from videophone to 3G cell phone), RTP flows are first passed through Asterisk to Radvision appliance, then are converted to H324M and then passed to ISDN-PSTN passing Asterisk again
 
Is this correct ?
How many B-channels per call are used ?
 
Regards

That's exactly the point of the 3G-324M stack! Otherwise, you could buy appliance at Dilithium or Radvision that do the job...

Hi,
 
This won't change 3G-324M stack development, but, is anyone aware of any (european) service provider offering 3G-to-IP gateway or MCU services ?
 
Using an Asterisk registered SIP softphone (eyebeam, for example), someone would be able to call a 3G call phone for a voice and video conference.
Cost would be purely based on call duration or maybe based on subscribtion fees and call duration.
 
Cheers
