I configured SIP on 2 IP phone using asterisk. I could dial through from one phone to the other, but when I pickup the phones and tried to talk, i don’t hear anything other than static noise.
At some point I was thinking it was the hardware that had issues, but when I set it up using vocal, i could call and talk.
Please I need someone to tell me what I am doing wrong or not doing.
I need help on this.
