Modem Hangs Up when trying to transfer calls

[Guest Baklan]

I have an Intel V92 Data Fax Voice modem running on 4.47.2 drivers (latest from Intel site).

When I try to transfer the call, doesnt matter PBX or conference, instead of flashing it just hangs up. I tried doing it this way:

!,,xxx-xxx-xxxx,,!

but still it doesnt work, like it doesn't recognize the ! command.

In VG Dialer though it can understand the flash command fine.

Any idea whats the problem here?

Sounds like the hookflash that this modem generates is too long for your PBX - and your PBX thinks the line was hung up - so it just finishes the call.

 

If you want to do call transfers you should use a Dialogic card - you can adjust hookflash length on Dialogic cards to match that which is required by your PBX, and then call transfers etc. will work.

Could you recommend some basic dialogic card. Don't need anything fancy, the cheapest I can get to get it to work with transfer feature.

A good entry-level card is the 4 port D4PCI. In US it costs around US$500 brand new.
