[Freeswitch-users] Original Caller ID/number after attended transfer

Hi Anthony, list,

we're working with Polycom Soundpoint 560 phones. But meanwhile I could solve this problem.

A 'global_getvar' showed me that 'ignore_display_updates' was 'true'. After setting it to 'false' I now get the original caller ID displayed when doing a transfer.

One point is left that I'm currently working on:

on incoming calls I add a leading 0 to the original number. I need to do this because if a internal member wants to call outside he/she needs to dial with leading 0.


        <action application="export" data="caller_id_number=0$1"/>

        <action application="export" data="effective_caller_id_number=0$1"/>

        <action application="set" data="ignore_display_updates=true"/>


The initial incoming call is working, the number has a leading zero. Doing an attended transfer to a phone I now have the original number (without leading 0). With a blind transfer it's working.

Any suggestions ?

Thanks in advance and best regards

if you get phones that support display updates (polycom, snom, cisco and a few others) yes. It already works.

What phones do you have?

Hi all,

is there a possibility to display the original caller ID & number after doing a attended transfer. External call to phone A -> calls phone B (I see caller ID & number of phone A) -> doing an attended transfer of external call to phone B (still caller ID & number of phone A).

Thanks in advance and best regards,
