registrar.hfosip.de

proxy.hfosip.de;lr

User

Enter here the Username (Benutzername), followed by '@hfosip@extrasip.de'. Extrasip.de is a registered address/realm from HFO Telecom. This is needed to properly register the trunk at the provider.

Dial command

The dial command is the command which is used in the asterisk software. The term {number:1}  means, that at the dialled number (e.g. 0089987654321) the first digit is removed. If you don't use a line access code (in most cases '0' is used), you have to remove the ':1' ! ! !

Group

Select here the previously created gateway group.

Update remote party ID (CLIP)

To display the correct extension at external parties, you have to use the P-Asserted-Identity (PAI) setting. If this is not selected, only the head-number (e.g. 0891234567-0) will be presented, no matter which extension is used for dialing.

From Domain

Enter here the Domain/Realm delivered by HFO Telecom

hfosip.de

Underneath the configuration parameter you will see a preview of the complete sip.conf file.
