Filip Frank commented on ASTERISK-27980:
----------------------------------------

Same problem for me, "I" option helps little bit(sometime CID is replaced, sometimes no). It depends lot on timing, if COLP update is processed before Set CALLERID(number) or not. Its because dialplan running simultaneously with COLP update. 

Example(part of dialplan in transfer context): 
-- Executing [737238335 at transfer:20] Set("Local/737238335 at transfer-00000069;2", "CALLERID(num)=00420773737556") in new stack
-- Executing [737238335 at transfer:21] DumpChan("Local/737238335 at transfer-00000069;2", "") in new stack
Dumping Info For Channel: Local/737238335 at transfer-00000069;2:
Name= Local/737238335 at transfer-00000069;2
...
CallerIDNum= 28000420773737556

And then INVITE have From: 28000420773737556 instead of required  00420773737556.
Workaround:
Adding Wait(1) before Set(CALLERID(number)) helps as wokaround. COLP update is then always processed before dialplan CID set.  

There is gerrit patch, but it was abandoned. My knowlage of asterisk code isnt good for fix it. :( So please reopen. 

I have problem in 13.x, 16.x

> Alice calls Bob.
> Alice does an attended transfer to Charlie.
> The Caller ID is modified to some ID using either CALLERID function or Dial options 'o([x])' on outgoing context before Dial Charlie's endpoint.
> But the From: header contains "Alice" on INVITE to Charlie, and not what is set before.
> The app Dial initially correctly sets CONNECTED LINE on outgoing channels as CALLERID of the originating channel.
> But then the app Dial reads pending CONNECTED LINE update on the originating channel and sets CONNECTED LINE on outgoing channels with this data.
> The processed pending CONNECTED LINE update already sets CALLERID on originating channel, so all pending CONNECTED LINE updates have to be ignored and removed before initialize outgoing calls.
