Hello. Can anybody help me please.
I have a FreePBX 188.8.131.52.
and a GSM Gateway Yeastar TG100.
I wana to Call out and in via GSM Network.
So i have createt an SIP Trunk on the Freepbx.
Calls witch ar goinig in (mobiletoip) works perfect.
But Calls IPtoMobile the Provider dosn’t Accepts the number and hangup.
I think the reason, it is because the Freepbx side send the INVITE with wrong number, so that TG100 call to a wrong number.
Have anyone an idea how i can change this option on my freepbx?
