Hello,

Sorry for a bit of a newbie post but we all had to start somewhere right ..

I'm wondering if someone can briefly explain the difference between blind and attended transfers and why they would generate two very different CDR entries.  From my own research, it seems that transfers are both ultimately a SIP REFER and thus seeing two different CDR entries just confuses me further.

Here's an example;

Attended xfer to extension
"0429123456","222","21","17","ANSWERED","2015-06-03 15:05:56"
"222","225","14","11","ANSWERED","2015-06-03 15:06:08"

Blind xfer to extension
"0429123456","222","9","7","ANSWERED","2015-06-03 15:08:54"
"0429123456","225","11","8","ANSWERED","2015-06-03 15:09:04"

So, is it possible to get the same behaviour as blind transfers for attended transfers - where the second entry displays the external PSTN CID of the connected party, instead of looking like a long on-net call?

We're running Asterisk 11 with various Cisco 79xx phones.  All extensions involved have trustrpid=yes, sendrpid=Remote-Party-ID and canreinvite=no.  We'll see the same behaviour between all on-net extensions as well, so it isn't a trunk config issue.

Thanks in advance,
