GRP2614 (1.0.0.31) After Transfer the other extension, not the caller is shown with GXP21xx


#1

After a Transfer with GRP2614 to an other GXP21xx, the other extension, but not the caller is shown.

After an Attended Transfer it is OK. The the caller from outside, that has been transfered is shown on the screen of the target extension.

I have set the “Trust Remote Party ID” and “Send Remote Party ID” already.
On the Phones the “Attended Transfer Mode” is set to P1376=1 (Dynamic).

The original caller-ID is only shown after Attended Transfer, but not after Blind Transfer:

Attended:

  • Call from +49179654321 to extension 12 (+49179654321 is shown)
  • Transfer Key pressed and 18 dialed
  • 18 speaks to 12
  • 12 hangs up - the call is transfered to 18
  • On the phone 18 is shown +49179654321 - This is correct!

Blind:

  • Call from +49179654321 to extension 12 (+49179654321 is shown)
  • Transfer Key pressed and 18 dialed
  • 12 hangs up directly
  • the call is transfered to 18 and ringing (12 is shown as caller, this is already wrong, should be the external ID)
  • 18 picks up the call
  • On the phone 18 is shown 12 - This is should be the external ID, like before…

It is the same with internal calls: Attended Transfer is correct - Blind transfer shows the caller-ID of the transferee not the original caller.

Hi,

In the call scenario you described, I assume extension 12 is the GRP2614. I’m also assuming a UCM or asterisk based PBX is being used here. In my testing with UCM61xx on 1.0.18.16 I can’t reproduce your finding. The third party receiving the call sees the correct caller ID. In fact, in the blind transfer scenario UCM sends the INVITE to the third party with the corresponding from/to along with remote party ID. GRP has no influence over these parameters. I suggest to take a capture on your UCM/asterisk PBX and PM us the trace along with the call info so we can provide some analysis.

Thanks

OK, I checked it again. It is a bit confusing:

With UCM6202 (1.0.19.27) - After an Attended Transfer with GXP2130 (1.0.1.135) (Ext. 12) to an GRP2614 (1.0.0.31) (Ext.11), the other extension, but not the caller is shown.

After a Blind Transfer it is OK. The the caller from outside, that has been transfered is shown on the screen of the target extension.

I have set the “Trust Remote Party ID” and “Send Remote Party ID” already.
On the Phones the “Attended Transfer Mode” is set to P1376=1 (Dynamic).

The original caller-ID is only shown after Blind Transfer, but not after Attended Transfer:

Blind:

  • Call from +49179654321 to extension 12 (+49179654321 is shown)
  • Transfer Key pressed and 11 dialed
  • 12 hangs up directly
  • the call is transfered to 11 and ringing with shown +49179654321
  • 11 picks up the call
  • On the phone 11 is shown +49179654321 - This is correct!

Attended:

  • Call from +49179654321 to extension 12
  • Transfer Key pressed and 11 dialed
  • 11 speaks to 12
  • 12 hangs up - the call is transfered to 11
  • On the phone 11 is shown 12 - This is should be the external ID, like before…

If the GRP2614 is the transferee it works correct. So it might be a problem of the GXP21xx-series, but not the GRP26xx, because this behavior is known from GXP21xx (Open support-ticket since 1 year).

I checked the same with an GXV3380 (1.0.1.8):
It is the same, when the GXV3380 is the one make the Attended Transfer, the ID is false. When the GRP2614 is the one making the Attended Transfer, the ID is correct.
