Attended transfer doesn't work

[Ryandc]

Okay, here's the system config:
SBS 2003 running Enterprise Edition 3cx
Linksys SPA922 and 962 phones
Grandstream 4108 Gateways.

I saw this same problem posted elsewhere on the forums. However, there was no response, so here we go again, this time with a server log:
Here's the error stack

Here's what happens: I call in. I then ask to be transferred. Attended transfer begins; I hear the hold music. Receptionist finishes the attended transfer and I begin speaking to the person to whom the call was transferred. After approximately 10-20 seconds, the call terminates.
Thoughts, anybody?

I've the same problem

I have the same problem, I upgrade my linksys SPA3102 to fimeware 5.7, but the problem still yet, but I can see that if I change the type of the line (Checked external line), in the firts seconds I can make out coming calls, or if reset my router or change outcoming delay, I can make one out coming call.

can some body anwer about this problem, I have configured like the manual, and I'm using my SPA3102 over my Internet Interface, and I put static IP ()fre ip of my network) , gateway (my gateway), dns (my DNS) ...

Them I can make incoming calls but this hung up for the linksys gateway make that my x-lite 3.0 disconect the call. I think that it's aVoIP to PSTN configuration error, but I don't know the solution, please can some body explain us the solution??? (I'm in spain)

Check on the phone interface - admin, advanced, Ext 1 tab - Call Settings section - Blind Attn-Xfer Enable: set to Yes.

I think that was what fixed my transfer issues.

call drop after 20sec after transfer

I am tearing my hair out!!! :cry:
I am using Linksys IP SPA942 phones, but I don't think it is related to the phones because it also hangs on the softphones.

We receive a call... transfer to another extension... bingo... the call drops after 15-20 secs after the transfer... can't find any help!!!

Anyone else having this issue?

here is a dump of the log:

"Transfer: wrong leg is connected" seems to be the explanation.

[LORD ORION]

Did you try

1) Uncheck "Supports replaces" on the extension, and if that doesn't work then
2) Uncheck "Supports reinivite" on the extension

 

[gleuto]
