Hi,

Do you use the gsm gateway? What's your gateway firmware version. Update it to the latest one,please. Then go to the gateway
> GSM
> Call waiting, and
select the gsm ports and set the call waiting fuction off. at the last, plase click the setting button.
Wish this will help you. If you still have problem, you can add my skype.

Best regards,

I use WGW1002G and the question is:
Is it possible to use this gateway for 2 simultaneous talks with one SIM card, or 4 simultaneous with 2 SIM cards? Not switching between calls but to use 4 separate SIP calls using only 2 SIM cards.

Hi sir,

For incoming calls: if you enable the call waiting, then one SIM card could support 2 simultaneous calls. otherwise, it only support 1 call.
For outgoing calls: one sim card only support 1 call.
You can create more than 2 sip endpoints using 2 sim cards. but the gateway only supports 2 simultaneous calls for outgoing calls. this means that you cannot make 4 separate sip calls at the same time. This is not because our device doesn't support it, but because this function is impossible to realize. the sim card operator doesn't support it.
Wish this will help you.

lindali, thank you!

What could be the reason of vibrating sound when second connection for one SIM card initiated using Call Waiting feature on WGW1002G? We are using latest firmware. Is it hardware or software limitation, GSM or SIP problem?
