I have tested on Yealink T58V displaying image from Call-Info header.
It works only with the version of Call-Info header:
Call-Info: <Image URL>;purpose=icon
The phone did not recognize another version: Call-Info: icon="URL".

Example INVITE message with Call-Info header:
INVITE sip:803@;transport=UDP SIP/2.0
v: SIP/2.0/UDP;branch=z9hG4bK-o-1548917061633031-040560-101
f: <sip:801@;user=phone>;tag=ecssO1548917061633040040560
t: <sip:803@;user=phone>
i: BA:7edbdc68d51a6fd8:7edbdc6ce8925c4a
User-Agent: Eltex ECSS-10 SIP
Max-Forwards: 69
m: <sip:801@;line=89d088c8080cc588>
Accept: multipart/mixed, application/sdp
u: presence, dialog, conference
Call-Info: <https://sites.psu.edu/siowfa16/files/2016/10/YeDYzSR-10apkm4-300x295.png>;purpose=icon
Category: 10
x: 1800;refresher=uac
Min-SE: 300
k: 100rel, timer, replaces
P-Eltex-Info: d.local 803@ 2437449096 sip1@igorbulanov <0.4056.0>/1 outgoing
c: application/sdp
l: 577

Is it possible on yealink ip-phones to enlarge the image received by incoming call through SIP-header Call-Info?
Are there any other supported mechanisms for receiving image of the caller during an incoming call?

Thanks and best regards, Igor (igor.bulanov@eltex-co.ru)

Hi, igor
Good day.
This is Jacky from Yealink Technical Support Team, nice to meet you.

(1)Currently, Yealink IP phones are able to download the picture from the URL contained in the Call-Info or Caller-Image Header of Invite message. Also, the "call info" of Yealink phones is based on the RFC standard protocol. You can refer to the link as below: https://tools.ietf.org/html/rfc6993#page-2
(2)In addition, we have a standard sample of our local tests that you can refer to the attachment.
(3)Could you please tell me which way do you want to download from SIP INVITE packets? May I know the reason you want to do it? And whether other phones support it?

Best Regards,
