Why can't I forward incoming calls?

Why can't I forward incoming calls?

Why can't I forward incoming calls?

(OP)
Hi all.  I have an IP403 Office with an Analog Trunk 16 expansion module, and 9 analog lines coming in for connectivity.  Normally, incoming calls ring a reception hunt group.  However, during lunch and after hours, we need those same incoming calls to go to an external number, an answering service.

I've set up a group called FwdAnsSvcGroup, set to linear, with one member, an extension called FwdAnsSvc, which is set to forward unconditionally to the number, 95551234, for example.  Forward huntgroup calls is checked.  In System Properties, Inhibit Off-Switch Calls is unchecked.

So, all seems to be set up right, and if I pick up an extension internally and dial either FwdAnsSvc's extension or FwdAnsSvcGroup's extension the call gets out fine.  However, if I set an incoming call route to FwdAnsSvcGroup or FwdAnsSvc, and then call the main number, it just rings endlessly and nothing ever picks up.  Call Status doesn't even show a call.  What I'd like to do eventually is have the night service group for the Reception group to be FwdAnsSvcGroup and have it forward to the outside line then, but that does't work either.

Thanks for the help.  This problem is killing me.

RE: Why can't I forward incoming calls?

On IP Office you cannot connect alog trunks together, you can only connect a incoming call from alog trunk to a ISDN trunk and nothing else.

RE: Why can't I forward incoming calls?

There is a separate "Allow forwarding" option hidden in the settings for each analog line. By default its off (ie. no forwarding). Worth a look though I had thought this would affect both manually and automaticall forwarded calls.

Note: The need for an extra forwarding restriction on analog trunks is because an issue is some areas with very unreliable disconnect signals where the incoming and outgoing trunks used for the forwarded call could both end up locked up after the call had ended.

RE: Why can't I forward incoming calls?

I did not think you could forward a call on Analogue lines full stop (Except select services direct from the exchange) - maybe just a UK thing.

And I'll probably get slaughtered now by everyone telling me how it can be done!! Ce la vie.

RE: Why can't I forward incoming calls?

the call forward is using the telephone system as a contrul unit. to forward the call the call comes in on line 1 and the telephone system forwards it to another number on line 2 as simple as that worls fine in the uk will try on a small dont forget to turn on the forward tab in the manager under the analouge line setting

"Allow Forwarding: Default = Not selected (Off).
When off, external calls on other trunks cannot be transferred back off-switch via this trunk. This prevents transfers to trunks that do not support disconnect clear. See also Inhibit Off-Switch Calls on the System | Telephony tab"

RE: Why can't I forward incoming calls?

also make sure you have disconect clearing set on your lines otherwise you lines wil get locked up..

600 to 800ms should be ok

Thanks for the help, sizbut and xlr8neo.  I had never noticed that "Allow Forwarding" option in the line properties, and that's exactly what did it.

What exactly is disconnect clear?  It appears to be set by default on the lines, so I guess I'm in the clear on that (no pun intended).  Would call status show if I had a line locked up?

RE: Why can't I forward incoming calls?

just check if you get a long call duration ie 100 mins or so, if you do get than speak to say bt or your line supplier and get them to set your dic con clearing to 800ms you neet to set your telephone system to below that say 500ms this will sort out any probs

RE: Why can't I forward incoming calls?

Disconect clear is a means of signaly to the telephone equipment that the call has ended,

if you were to atempt a trunk to trunk transfer without it the pbx would be unable to tell taht the call has fineshed & keep both circuits of hook indefinetly.

Disconnect clear is not usualy enabled on domestic trunks ( & asking for it can confuse some domesitc suppliers, especialy in the uk)
