Asterisk with T21P E2 provisioned - call problem

I'm provisioning some T21P E2 phones (firmware using the same files that I already use with T21P phones (fireware X.72) but I'm having call problems.

Extensions can be registered, but when I try to call I received the following error in display:

call failed - forbidden

In Asterisk, I noticed the following messages:

[Jan 29 09:01:46] WARNING[2559][C-0000058e]: chan_sip.c:16393 check_auth: username mismatch, have <3257>, digest has <IP Phone>
[Jan 29 09:01:46] NOTICE[2559][C-0000058e]: chan_sip.c:25569 handle_request_invite: Failed to authenticate device "3257" <sip:3257@>;tag=2901584664

And in SIP packet I can confirm that digest username is wrong:

<--- SIP read from UDP: --->
INVITE sip:3232@ SIP/2.0
Via: SIP/2.0/UDP;branch=z9hG4bK2765055407
From: "3257" <sip:3257@>;tag=2901584664
To: <sip:3232@>
Call-ID: 0_3569350556@
Contact: <sip:3257@>
Authorization: Digest username="IP Phone", realm="", nonce="1801b82b", uri="sip:3232@", response="7cbb8fb8cd55261a44868fbb50434069", algorithm=MD5
Content-Type: application/sdp
Max-Forwards: 70
User-Agent: Yealink SIP-T21P_E2
Allow-Events: talk,hold,conference,refer,check-sync
Content-Length: 308

I didn't find this "IP Phone" string anywhere in my configs.

Anybody else is having this issue?

Or anybody else is using T21P E2 with firware X.80 provisioned with Asterisk and it's working fine?
