Hope everyone is well !! I've got an issue in India. I just brough up a new site in India and I am having a problem with PSTN callers trying to connect to an extension by enter a 4-digit extension number from Unity auto attendant. What is happening is when callers dial our main number the call get routed to Unity aa and no mater what extension they enter it always route the call to the operator extension. But if I dial auto attendant internally then everything works fine. I have a feeling DTMF tones are not being sent when dial from PSTN.
Has anyone run into this issue in India ?
Here is the call flow: PSTN caller -> 3825 router with vic2-4FXO -> Unity AA -> IP Phone
and one thing I noticed is all analog lines in India are centrex lines. This might have something to do with the issue.
Thank you all in advance !!!
