Chapter 33 Group Management and LCR2 (this could be an LCR for long distance calls via your VoIP service provider ITSP). AG2 is associated with LCR1 only. In this case extensions belonging to AG1 can make calls via all outbound line groups, whereas extensions in AG2 are limited to calls to your local telephone company and your branch office. Figure 348 Group Management - Authority Group to LCR AG1 Sales AG2 Research LCR1 LCR2 PSTN TrustedPeer ISG Internet ITSP Managing Outbound Line Groups Outbound line groups include SIP, FXO, ISDN BRI Trunks, and Trusted Peers as defined in Chapter 30 on page 477. For management purposes the ISG50 grants rights to calls coming in via these channels based on the outbound line group they are part of. You can manage incoming calls by associating (linking) outbound line groups with: • Authority Groups - When you create an outbound line group it is by default linked to all authority groups created on the ISG50. This means that calls coming in via this outbound line group are authorized to call any extension created on the ISG50. You can remove the link from an outbound line group to an authority group to stop incoming calls from an outbound line group from going to a specific authority group. 528 ISG50 User's Guide
