Hi
As you know we have three different types of transfer.
1- Forward on Busy or No Answer or Always before Off Hook
2- Blind Transfer : one-step transfer , an unsupervised transfer.
3- Complete Transfer : in a supervised transfer. A supervised transfer means that the party receiving the transferred call is consulted by the party transferring the call, before the transfer is completed.
Please let me know which one of these transfer types is supported by LanScape Media Engine.
There is a function "TransferLine" which as I tested it only supports Blind Transfer. Let me know any other function if exists.
Thanks
Jalal Abedinejad

Hi Jalal,
Unattended Call Transfers:
There are two API procedures that support unattended transferring of calls. They are:
TransferLine()
TransferLineUri()
Using these two API procedure, the media engine performs unattended call transfers using the “Bye-Also:” header that was in use prior to RFC 3261.
Attended Call Transfers:
We are aware of attended call transfer operations as described using the REFER method as per RFC 3261 and are working to implement this capability into the product.
Forward on Busy or No Answer:
We have not had much request for this functionality. Currently this would be handled by returning to the initiator of the call a SIP response in the 3xx range (SIP redirection responses). The media engine does not handle this at the moment but our software group states that it would be possible to add this capability in a future release.
What would happen here is that the media engine (and the application) would be configured to respond with one of the SIP 3xx redirection responses when either all receiving phone lines are busy or the incoming call is not answered in a specified amount of time.
If you want to elaborate on how you specifically use “Forward on Busy or No Answer”, we would like to hear your perspective.
Repost as needed,
Support

Hi
Forward on Busy or No Answer:
Another name for these sort of transfer is Divert. There are three types of divert.
Divert always : This is used by softphone when the user does not want answer any other call on that extension. So he/she diverts his/her extenstion to another extension or PSTN number. This is what is used usually on mobile phone sets.
Diver On Busy : This is used when softphone user is usually busy and does not want miss any call, so he/she diverts his/her extension to another extension or PSTN number when Busy.
Divert On No Answer : This is used when softphone user wants another extension answer his/her calls when his is not at the desk.
These options and also Attended Call Transfers are critically needed by our customers. Please put these options on your next release.
Thanks
Jalal Abedinejad

Hi Jalal,
We have forwarded your additional information regarding call transfer to our developers.
When we (the support group) send to the software team new and unique product requests, the development team places them into a product “road map” database that is used to plan future product releases.
You are doing a great job at identifying new functionality for the media engine. Be sure that we will work hard to obtain this new functionality for you and all other customers.
Thanks Jalal!
