The only supported GSM device for 3CX is the beroNet GSM gateway:

Best get one of these and stick to using the Raspberry pi as an SBC only.

Thanks the model is very difficult to get in my county India and after sales becomes problem also I have seen GSM Gateway like Symway working fine but I am instead interested to know can raspberry pi act as GSM Gateway with GSM Module attached

That would probably be one for the Raspberry Pi forum, this is not a supported configuration with 3CX.

As for the GSM gateway - ebay perhaps ?

Others have asked, in the forum, about using a gateway device behind an SBC. I don't recall anyone that has managed getting it to work. The 3CX SBC is designed for SIP phones and trunks work in a different was when compared to SIP sets, or ATAs.

Remote Gateways are not supported, but, depending on the complexity (number of trunks), and the remote routers capabilities/limitations, it may be possible, with some trial and error, to make it work. No guarantee.

You could connect using VPN, that should work.
