Hi, I am new to 3cx and need some help. I have CISCO IP SPA504G phones with 3CX and Patton SN4114 PSTN gateway. when i make outbound call i get please dial 1 before outbound number even if I dial 1. after few attempts I can dial the number. But I get this annoying message every few calls. Is this related to phone itself or some configuration in 3CX? Please help! Thanks in advance!
