[cisco-voip] 8 channel GSM gateways?

[Lelio Fulgenzi]

I hear what Robert is saying though. 

We have a group on campus that has deployed 150 cell phones and are using that as their primary device. 

They're worried about going over their "free" monthly minutes. After which, costs are high. 

By getting a GSM gateway, with SIMs on the same network, we can add these to their "family" plan, which means unlimited inbound/outbound calling to/from these devices. 

I'd have to weigh the costs of implementation with the savings.

We have done something a little different, Cisco Router with Verizon Data card, put cisco phones on the edge. Not your case, But could you get a SIP provider, would that not be cheaper solution than Cell Phones????

I'd be interested if you find one and go with one. I have dealt with a client in same country who does this with FXO ports and a mobile phone device like you, but haven't heard of any issues so haven't really looked into alternatives.

this sounds interesting. 

are your mobile devices isolated to particular telephone numbers (or groups) that allow you to make the route patterns manageable? in North America (if you don't already know) with number portability, there is no such grouping. 

that being said, my curiosity found this:

the dinstar ones look neat. 

good luck

One of our offices (in Brazil) wants to deploy 8 cell phones to make 
calls to cellular destinations cheaper. (Cell provider has cheap 
on-net calls) 

We've had bad experiences with analog gateways in the past (disconnect 
supervision problems). 

Does anyone have any recommendations for an 8-port GSM gateway (either 
PRI or H.323/SIP interface) which can be used in Brazil? 

If we do manage to find such a box, do you just pull the SIM cards 
from 8 cell phones and plug them into the box? 

Thanks.
