I have an Asterisk with 2 trunks (A and B)
All works fine except if I forward calls incoming on trunk A to a specific public number called via trunk B : I have no ringing tone and no voice. If I call this specific number from an internal device, it works.
Except this, my pbx has been working fine for many years.
Do you think it could be a codec problem between the trunks? How could I check this in my SIP capture?
