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: http://www.voip-info.org/wiki/view/VoIP+Gateways#CellularMobilePhoneGateways the dinstar ones look neat. good luck --- Lelio Fulgenzi, B.A. Senior Analyst, Network Infrastructure Computing and Communications Services (CCS) University of Guelph 519‐824‐4120 Ext 56354 [email protected] www.uoguelph.ca/ccs Room 037, Animal Science and Nutrition Building Guelph, Ontario, N1G 2W1 ----- Original Message ----- From: "Robert Kulagowski" <[email protected]> To: "Cisco VOIP" <[email protected]> Sent: Thursday, April 24, 2014 11:35:44 AM Subject: [cisco-voip] 8 channel GSM gateways? 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. _______________________________________________ cisco-voip mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-voip
