Call forward notice message possible?

Sometimes we need to forward some SIP trunks to another telephonenumber temporarily but we would like the receiving party receives a message or tone he/she knows it's a forwarded call.

 

For e.g. when you call +31201234567 you would hear as a caller "one moment please your call is being forward" and the other party to which the call is forwarded receives first a message 'this call is being forwarded from office A' and then forwards that call.

 

Other solutions are welcome to, we want to hear something when a call comes from this forwarding.

 

On level of extensions or trunk, both solutions are welcome.

 

Thanks in advance,

Ramond

Hmm, what is the use case here? Is it only for the cell phone? There we still have the topic that we want the user to confirm the call because of the cell phone mailbox problem.

 

It would also mean that the first few seconds of the conversation are cut off? Or do you want to mix it with the audio of the other side?

Actually it's not a cellphone. It's a receptionist who will answer this phone, appearantly via POTS.

 

If I don't fill in a cellphone but a normal phonenumber, the receiver hears a tone/message?

Of course the PBX does not care if it is POTS, cell phone or just a SIP URI (actually, there is no way of finding out). The point behind the cell phone inclusion in an extension is that the caller actually has no chance to find out that the call was redirected. The PBX user should be able to hide where he actually is. That is different from the redirection after timeout, when the PBX makes an annoucement ("please stand by while redirecting") and then actually plays the ringback tone of the POTS line (which may include comfort noise in the beginning).

 

The biggest problem is the propagation of the caller-ID. It is a reality that most ITSP are today not able to differentiate between display-ID and network-ID, and then those redirected calls always seem to come from inside the PBX. Playing an annoucement could be a "poor mans" original caller-ID - and it would also solve the problem that cell phones tend to redirect calls to mailboxes.

So I can't offer them a solution for this. It's like you say. ITSP does not support callerid sending out, which was ofcourse the easiest for the receptionist she knows she has to pickup the phone with other greeting. But as this isn't planned on a short term I have to invent some other workaround for them.

 

If anyone have suggestions, please let me know.

The next version has a cell phone forking that may read out the number and asks the user to press "1" to answer the call. That might be a workaround.

Can you force a number? What if your ITSP does not support CID? Before the number is said a text is spoken? Like "Hi this is pbxnsip forking service, number blah blah?" And this "Hi this is pbxnsip forking service" is a wav file which can be changed/customised?

It gets straight to the point and says "978-746-2777 is trying to reach you. Press 1". That has the benefit that you hear the original caller-ID (solving a common problem when redirecting the call) and you hear it right at the beginning.
