Message-ID: <8638@accuvax.nwu.edu> Date: 31 May 90 22:31:06 GMT Sender: news@accuvax.nwu.edu Organization: TELECOM Digest Lines: 19 Approved: Telecom@eecs.nwu.edu X-Submissions-To: telecom@eecs.nwu.edu X-Administrivia-To: telecom-request@eecs.nwu.edu X-Telecom-Digest: Volume 10, Issue 412, Message 2 of 13 We are in the process of ordering DID, a 600 number block. When costing this out we were thinking of converting our existing trunks over for DID use. Now the local carrier, PacBell, is telling us that DID lines are for incomming calls only; we can not use them for making calls. This is going to require us to keep a separate group of trunks for outgoing calls with no overlap of the two groups. That means the total number of trunks will have to be larger to handle peaks in incoming and outgoing calls and that means more trunk charges and more trunk interfaces for our PBX. So are DID lines really only for incomming calls? Is there a technical reason or is the carrier trying to charge more? Jerry Aguirre
