Ok ggrraay . I followed Darkside step like this:
Setup a new custom trunk for your dongle under Connectivity → Trunks → Add Custom Trunk and set these values:
Trunk Name: to-my-cellphone
Outbound CallerID: Your SIM card number with country code (with a plus sign at the beginning)
Custom Dial String: dongle / dongle0 / $ OUTNUM $
::::::::::::::::::::
Now, how do I make a call from the dongle and Issabel? Do you have a knowledge of this? TK
