Caller-id after attended transfer not working properly on T19P/T41P

[Lucia_Yealink]

Dear Customer,

For this parameter, it works for both invite and update message which pbx send to the phone to refresh the caller id.
account.X.cid_source=
0：FROM
1：PAI
2：PAI-FROM
3：PRID-PAI-FROM
4：PAI-RPID-FROM
5：RPID-FROM
I just check the pcap you provide and locate the problem, in your situation, the pbx send two update message to the T41P, both of the two update contact the PAI.
The fisrt one is: P-Asserted-Identity: "Daniel Diaz" <sip:142@10.176.255.0>\r\n
The second is: P-Asserted-Identity: "227605147" <sip:227605147@10.176.255.0>\r\n

The phone read the caller id from the PAI of the first update message.
Suggestion: Please let the pbx send only one update message with the correct PAI.
