Using the LANCOM VoIP router and the enhancement with VoIP functionality within your telephone structure is designed to support the users' telephone behavior with the greatest possible convenience. One of the core aspects of this is the use of "spontaneous" or "automatic" outside line access, a feature that is familiar to users of standard PBX systems.
- Most PBX systems are configured in such a way that the telephone subscribers must dial a "0" before the desired telephone number in order to gain access to an outside line - that is, to carry out a telephone conversation via a public telephone network.Without the "0" prefix, the number dialed is considered to be an internal number from another extension line on the private PBX.
- If "automatic outside line access" is set up, all numbers dialed are directed over the public telephone network. In this case, internal telephone calls to other extensions are not possible or only possible when a special symbol is dialed before the number.
When the telephone structure is extended with a LANCOM VoIP router, a variety of new possibilities become available for connecting telephone terminal equipment. This includes the existing analog or ISDN telephones (where necessary, connected to the respective PBX) or VoIP terminal equipment such as SIP telephones or PCs with VoIP software.
As a new and central building block in the telephone structure, the LANCOM VoIP router assumes many of the PBX tasks for the terminal equipment connected to it. As such, you can also set up the automatic outside line access for the terminal equipment connected to the LANCOM VoIP router directly for the ISDN or SIP subscriber groups, thereby adapting it to existing telephone behavior.
- When automatic outside line access is turned off, subscribers must dial a "0" before the desired number in order to carry out a telephone conversation via a public telephone network.All calls without a "0" preceding the number will be treated as calls to internal extensions within the private telephone network.
- If automatic outside line access is turned on, all numbers dialed will be directed over a public telephone network.For telephone calls to internal extensions, a special symbol or a specific number combination must be dialed before the number. With the default settings, when automatic outside line access is enabled, a star * is activated as the identification symbol for an internal number. This setting can be adjusted to match the character that you are familiar with.
Note: If you operate the LANCOM VoIP router on the extension line of a PBX, we recommend that you configure outside line access for the router in the same way as for the PBX so that the behavior remains unchanged from the user's perspective.
