We are trying to connect three VOIP phones, two that are supposed to be used externally from someone's office and one that is supposed to be used within the office. The issue we are running into is that from within the office we can use to the phones just fine, but from outside the office, the phones are not operational. From what I understand, they are supposed to be connected to the office VOIP from the two user's homes. So they would someone need to be connected back into the office...maybe an ACL modification or creation is needed?
This is being configured through the ASDM, so whatever solution you might offer needs to be done through the ASDM.
