I have a SIP Trunk configured in my asterisk, for example if i dial a number and an IVR answer the call and i press on options of the IVR System, anything happen, is like the SIP Trunk dont detect i’m pressing an option.
I have done this for example:
Call 1800-000-0000 --> Thanks for call to BLA BLA BLA --> For Sales press 1, for support press 2
When i press 1 in the phone, anything happen, but this just happen to my using the SIP TRUNK, if i dial using my normal Land line, and press 1 using my analog phone, i can hear the other options…
What i hape to configure in my sip trunk, Have ever happen to you this situation? How to fix it?
