Configuring outbound rules on GSM Gateways

Hello,

I have a WGW1002G GSM gateway connected to 3CX.
I have created 2 SIP trunks, and created inbound and outound rules, screenshot attached below.

But even i specified a rule to route calls from GSM1 (SIP trunk) to port-gsm1, and created an outbound call on 3CX to route calls from extension "000" through GSM1, still all my calls go through port-gsm2.

How to configure Openvox GSM to choose outgoing sim card?

Thank you so much.

hi,

if you use two sip trunks, you can add the "fromuser" parameter in VOIP--> sip trunk config-->Advanced:Registration Options to try.
if still have problem, you can add my skype, i will help you to check it remotely.
