Have OBi 110 and callcentric. Could receive/make call in general. However, each time I called someone such as a customer service and need to punch in a number for menu selection, the other side seem never could get it right. Not sure whose issue it is. Anyone has similar experience? Thanks.
Try Physical Interfaces -> Phone Port -> DTMFRxMode: Software.
If that doesn't help, set it back to Hardware and try ITSP Profile A (or B, whichever you use for Callcentric) -> DTMFMethod: InBand.
For a free DTMF test on CC, dial the iNum 011883510000000092 and when prompted, dial a string of digits followed by #.
Thank you Stewart! I was looking for this. I'm using Google Voice and had the same issue and switching to Software fixed the issue. Mine seemed horribly delayed or would only register if I hammered the number about 5 times.
Thanks for the reply. Somehow all the fields on the expert config page are read-only.
Sorry my bad. Found it, thanks.
