Hi

can anyone recommend a two port GSM gateway for an Officeserv 7200.

I'm not overly worried about connectivity (it can be BRI, POTS or SIP based) as long as it's relatively low cost and reliable.

Thanks B

I forgot to add, the system can be basic as all the least cost routing etc will be done by the OS 7200. The only useful tool needed is routing/load balancing based on the number of minutes left on each SIM card.

Your last requirement is going to be hard.
If all sim cards are on the same plan then i would set the trunk group to distribute.

Not sure if they're available in the UK, but i use a brand called aristel.

They make PSTN and BRI versions.

1 or 4 channel PSTN, and 2 channel BRI (they discontinued the single channel BRI model).

I've also used matrix which are made in india, they have PSTN, BRI and PRI GSM.

a PSTN GSM has no smarts usually, that's more so in the ISDN models.

Use to put lots of gsms on systems
you can plenty of them on ebay
I don't find much use for them now

I've used then on the analogue trunk ports with mixed success - the problem I found was the lines not being properly dropped at the end of a call.

However I hope that you find a solution.
