3.5. Programming the External Lines
The Opera 240 may have up to 2 ISDN Primary Rate Accesses, up to 12 ISDN2 Basic Rate
Accesses or up to 60 SIP trunks, or combinations of the above, with an upper limit of 60 outside
channels. The ISDN lines connect to the ISDN interface modules described earlier, while SIP
trunks are configured using the registration information from the provider, as described earlier.
When ISDN2 basic access trunks are connected, you must program the ISDN telephone
numbers associated with each T0 interface into the Opera system. These numbers are entered
on the ‘External Number List’ as shown below.
Similarly for the SIP trunk numbers associated with each of the SIP accounts:
When the external numbers have been entered in the white boxes, press ‘Save’ and ‘Back’.
