Hi, I have a strange problem I was hoping someone could help me resolve. I have set up a new phone system using asterisk-1.8.11, and everything is working fine with one exception. When users call in to our main number and get the automated attendant, they can go through the menu options and select an option as programmed. HOWEVER, on some land lines, not all digits are received. This does not happen when using a cell phone or a softphone, only certain land lines (2 out of 3 tested).
For example, when calling in and pressing 226 (for local extension 226) these errors occur:
– Invalid extension ‘6’ in context ‘attendant’ on DAHDI/1-1
– Invalid extension ‘26’ in context ‘attendant’ on DAHDI/1-1
So some of the digits are coming through, but not all and so the person gets sent back to the beginning of the attendant. One land line we tested was not able to get through on any attempt.
Has anyone seen behavior like this before, and if so how was it resolved? Any help is greatly appreciated.
