Transfer Call Issue

[Guest Phillip]

My System

1. IVG 4.8.47

2. Dialogic 5.1.1 SP1

3. Board: Dialogic D4/PCI

4. OS: Windows 2000

5. Phone Line type: Centrex lines from Qwest

6. Location: New Mexico (USA)

 

I have a strange problem with transferring call that seems to be specific to being transferred to a cell phone, and specific to one cell Phone Company.

 

The script I have looks up the number to be transferred to from a database. A caller is given an option to speak to a live person and the call is transferred.

 

The script works fine for all transfers, except to a certain cell phone provider.

 

What ends up happening is the instead of transferring the call, the call never hangs up, but instead is treated as a new incoming call.

 

See trace below.

 

Should a transfer call module be followed by a hang up module?

What should I set the paths too?

 

On {Success} Goto [Hangup Call]

On {Fail} Goto [Hangup Call]

On {Timeout ?} Goto [Hangup Call]

 

Thanks!

It looks like the transfer is done OK, and about 10 seconds later a new call arrives...

 

Some telephone systems behave like this when a blind transfers is not successful - the original call will be presented back to the party making the transfer.

 

You should speak to your phone company to see what is happening here and why you are having problems transferring calls to that particular phone number.

Why is it that I can connect an analogue phone to this line and accomplish the call transfer manually, but not using IVG? I

 

n fact I can answer the incoming call, flash hook, dial out bound and hang-up, before the first ring, and the call is still transferred.

 

Again, If I can do it manually, I am assuming it should be capable of being done programmatically.

I solved the issue by adding some commas after the number to be dialed. Doing so gave the system some time while the call was transferred to a cell phone. It appears that some cell phone carrier services are slow to ring when dialed so the call was just getting loped back.
