8945 Authentication Issue

I have SCCP 8945 phone in my lab that I can't make authenticate with UCM 9.1. Diggin deep down revealed that for some misterious reason the phone tries to add a domain name to its device name. It tries to grab domain name from DHCP and if's not configured simply leaves trailing dot (.) so that device name looks like this "SEP20BBC020215D.". Naturally this name has no chance to be authenticated. Here's short exchange captured by wireshark:

GET /ccmcip/authenticate.jsp?UserID=phone&Password=phone&devicename=SEP20BBC020215D. HTTP/1.1\r\n
HTTP/1.1 200 OK
Set-Cookie: JSESSIONID=6BB2F3CEF1F001948B45A6E1056DF868; Path=/ccmcip/; HttpOnly
Content-Type: text/html;charset=ISO-8859-1
Content-Length: 13
UN-AUTHORIZED

 

If I copy the GET request into browser address bar and remove trailing dot it authenticates alright. Same thing happen with my non-8945 phones. They don't try to add the dot to their name and authenticate fine:

GET /ccmcip/authenticate.jsp?UserID=phone&Password=phone&devicename=SEPE8B74838391B HTTP/1.1\r\n

HTTP/1.1 200 OK

AUTHORIZED

 

So, my question, is this behavior expected from the 8945 phones and domain addition can be disabled somehow somewhere? To me it looks like a bug but maybe I'm missing on something there.

I.m using SCCP8941_8945.9-3-2-11.loads firmware.

Thanks,

Victor

Sure. Don't know what you are

Sure. Don't know what you are looking to find there but here you go

asa5505# sho run | in dhcpd
dhcpd auto_config outside
dhcpd address XX.XX.71.65-XX.XX.71.126 inside
dhcpd option 150 ip XX.XX.71.191 interface inside
dhcpd option 66 ip XX.XX.71.191 interface inside
