Registration problem with SIP 3911

Unanswered Question
Sep 17th, 2009

I used in the configuration the following commands:

ip dhcp pool sip_3911


client-identifier 0100.1aa1.1b97.14


option 150 ip

tftp-server flash:SIP3951.8-1-1b.loads

tftp-server flash:SIP3951.8-1-1-4.zz

tftp-server flash:DSP3951.0-0-0-2.zz

tftp-server flash:BOOT3951.0-0-0-9.zz

voice service voip

allow-connections sip to sip


registrar server expires max 1200 min 300

voice register global

mode cme

source-address port 5060

max-dn 20

max-pool 10

load 3911 SIP3951.8-1-1b

authenticate register

tftp-path flash:

create profile

dialplan-pattern 1 ... extension-length 3

voice register dn 1

name SIP_Phone

label SIP_3911

number 391

call-forward b2bua noan 15000 timeout 20

call-forward b2bua busy 15000 timeout 20

allow watch

voice register pool 1

id mac 001a.a11b.9714

type 3911

number 1 dn 1

dtmf-relay sip-notify

codec g711ulaw

username user1 password Cisco

As i pick up the phone I get a busy number. The phone seems that has the right parameters, SIP configuration: number, name and authentication name, correctly loaded its firmware and got ip address but is not registered, this could be an authentication problem but it doesn't seem so due to the authentication register and user and password are correctly been set.

Please take "debug ccsip messages" and "debug tftp events" after your turn on the phone. Do not enable any other debugs.

The only logs that i get with both debug enabled are the following:

Even though I am a bit confused because i change the simple value of number or try to change the firmware just in case i had it wrong and it keeps displaying on the phone the old data.

Check SEP001AA11B9714.cnf.xml what contais as phoneload ?

perhaps delete and generate it again.

For SIP phones on CME, after any config changes you make, you need to do execute 'create profile' under the voice register global, this will build the config files again. Unlike Skinny phones, for SIP phones you have to do it everytime to update the profile.

Also, can you provide the following output

show voice register global tftp-binding

I have checked the .cnf.xml and seems everything correct. I have deleted and generated it again.

Reloaded the phone and it gets the name, number and firmware correctly but there is no way to get it registered.

Seems that debug ccsip messages doesn't give any kind of messages.

I have taken as well debug tftp events:

CME-Telenor#debug ccsip messages

SIP Call messages tracing is enabled

CME-Telenor#debug tftp

CME-Telenor#debug tftp events

TFTP Event debugging is on

I have no idea what .xml stands for and neither English_United_States/ld-sip.jar, where should I get them from?

On the phone i have number, name and authentication name well taken. There is no vlan created and is using the default one.

Paolo Bevilacqua Mon, 09/21/2009 - 10:36

Can you post the SEPxxxx.xml file ?

The ld-sip.jar is just a language file and you do not need to worry about it.

mariapenilla Thu, 09/24/2009 - 02:19

I found the error!!!it was due to sip-ua

i had there configured no trasport udp and no trasport tcp.

I can't enable it because i have a bug on my IOS and if I enable it it will produce high cpu usage.

Do you know any stable IOS working on router 2801 where can i use the 3911?
