i plan on buying 4 residential lines for our small office and i was giving some thought. we'd like to have one main number that can transfer calls to the other lines. but seeing that i have 4 different individual lines with different numbers, im not seeing hows thats possible, without tying up a line on the main phone. i would think i would need one DID with multiple simultaneous connections. can someone advise me. thanks. -------------- next part -------------- An HTML attachment was scrubbed...

What provider? Pots lines? SOME providers will provide hunting on residential lines, but not all, and most probably not 4 lines. Hunting does not require any thing more than the providers switch programmed to do so, but most will not do more than two lines. VOIP it all depends again on the provider. Residential can be fairly restrictive Since you say "our small office" you probably will have to step up to business rates. Since you don't specify even what part of the world you are in, it is hard to say much more.

Some telcos will set up your lines so that the calls will go to available lines, rather than the first one.

The first channel will be your incoming number. If busy, it will roll to line 2, line 3, etc until it finds an open line. This is done by your telco. You'll have the last line roll over to the first line. In the event that all 4 lines are in use, callers will hear a busy signal, or if you have telco supplied voicemail, they'll get your Telco voicemail. For dial out, you will want to start dialing out in descending order (in order to prevent a thing called Glare). Use a capital "G" in your dialplan to dialout in descending order. You'll also probably be better off getting SIP phones for your internal phones, because calling between them will not tie up a line, and you won't run into IRQ issues with cards. as you'll just need one TDM400P

Subscribe to call forwarding on each line, and program each line for "call forward on busy" to the next line of the four. It will accomplish the same thing as the trunk group approach above.
