I checked the PCAP file which you sent to me.
The phone dial parkpos_2 to retrieved the call.
The server respond 200 OK. In 200 OK message, there is no any PAI header contain the extension number. So the phone just show parkpos_2.

Normally, when you dial out, the phone will show dial number.
But after building call, if the 200 OK message contain PAI header.
The phone can configure to show refer to PAI header.

But in this case, the 200 OK header don't contain PAI header.
So there is no way to show extension number.
