Cisco 7960 registration problem

Cisco 7960 incoming problem

Hi

I am using Cisco SIP firmware version P0S3-08-8-00 for my Cisco 7930 IP Phone.

I am using the following values for SIPDefault.cnf

; sip default configuration file
#Image Version
image_version:P0S3-08-8-00 ;
#Proxy server address
proxy1_address: [I]asteriskipaddress[/I] ; 
proxy_register: 1;
nat_enable: 1
nat_address: [I]ip-phone-gateway-ip-address[/I]
nat_received_processing: 1

I've successfully managed to make calls using Cisco 7960 IP phone.

But the problem is the account is not registered with the server. I think authentication is done only at the time of calling.

Can someone please advice me where i am going wrong with my setup.


Thanks in advance
Vino

The phone is now registered.

But the problem is, incoming calls to the Cisco phone is directly going to the extension voicemail. But outgoing from the phone is perfect.

Can anyone please help me to sort it out?

Thanks
Vino

Do you have a phone config file in the tftpboot folder?

here is a template from my setup

Make a file with the above, adjust settings to your situation, name it SIP000000000000.cnf with the 0's being the mac address of the phone. Put it in the tftpboot folder.

Hi

Im using a similar phone configuration file as you've shown to me.

Everything seems to be fine except the Incoming. Since Incoming is directly going to the voicemail. But the account is registered with the server and shows at the CLI as

Addr->IP     : [I]dsl_public_ip_address[/I] Port 64613
Defaddr->IP  : 0.0.0.0 Port 5060
Def. Username: [I]extension[/I]
Codecs       : 0xc (ulaw|alaw)
Codec Order  : (ulaw:20,alaw:20)
Status       : OK (143 ms)
Useragent    : Cisco-CP7960G/8.0
Reg. Contact : sip:[I]extension[/I]@[I]dsl_public_ip_address[/I]:5060;transport=udp

I can see that, there is a mismatch in the port used by the phone and the port seen in the Registration Contact.
Will this create a problem?

Also I have question with my SIPDefault.cnf.

; sip default configuration file
#Image Version
image_version:P0S3-08-8-00;
#Proxy server address
proxy1_address: asteriskipaddress;
proxy_register: 1;
nat_enable: 1;
nat_address: [SIZE=6][COLOR=Red]?[/COLOR][/SIZE]; <---What should i use for this option?
nat_received_processing: 1;

Is the server unable to identify the phone local ip address?

Im getting tired of finding the solution....Please help....

Many thanks
Vino

Ciscos can be an itchbey to setup

Here is my sipdefault file.
I have my external IP address in the NAT field.
The 79xx can be a real pia to get going on SIP, once you do they are rock solid.

Dumb questions to ask:
Have you reset the phone by pressing * - 6 - Settings buttons simultaneously?
Are the NAT settings correct in FreePBX and match the phone?

(i just checked mine for reference and 2 are set to use NAT, 2 aren't)

Have you looked at the log files (not cli) to see whats going on?

Also my Asterisk server is on a direct public ip address and on a different location. My Cisco IP phone is with the private ip address on another location. One quick question, does Cisco 7960 IP phones support NAT ? .i.e. to register and make calls with a public server?

Because my other endpoints like grandstream, snom, etc, are working with the same asterisk server without problem.

Many Thanks
Vino

You definitely have this in your SIPDefault.conf ?

# NAT/Firewall Traversal
nat_enable: "1"
nat_address: "Static IP where the phones located"
voip_control_port: "5060"
start_media_port: "16384"
end_media_port: "20000"
nat_received_processing: "0"
# Proxy Registration (0-disable (default), 1-enable)
proxy_register: "1"

# Phone Registration Expiration [1-3932100 sec] (Default - 3600)
timer_register_expires: "3600"

# Codec for media stream (g711ulaw (default), g711alaw, g729)
preferred_codec: "g711ulaw"

# TOS bits in media stream [0-5] (Default - 5)
#tos_media: "5"
# Inband DTMF Settings (0-disable, 1-enable (default))
dtmf_inband: "1"

# Out of band DTMF Settings (none-disable, avt-avt enable (default), avt_always - always avt )
dtmf_outofband: "avt"

If you have then check both your firewall port forwardings.

 

[vinod]

Did you mean to put the Static IP of my DSL line, where the Cisco Phone sits in?

Many Thanks
Vino

 

[jpe]

The static ip address where the PBX is residing goes there, not where the phone is.

 

[OTA]

Can you try the phone on the same network as the PBX? Process of elimination. Make sure the phone works on the same network as the PBX first, then worry about bringing it outside that network.

The Ciscos absolutely support NAT. I've actually had better luck with them than the Grandstreams. I've also never had to put anything in the nat_address line of the Cisco conf file. About half of my extensions are outside of the office LAN, most of them are on dynamic IPs, thus I don't have the luxury of spec'ing out an address. Literally, the nat_address line for my phones is:
nat_address: ""

This feels like a firewall issue or a fat-fingered config issue in either the extensions.conf or SIPxxxxxxxx.conf.

I'm currently staying at a hotel right now, so I have NO control over this network nor their firewall. Sitting at a private address so there's definitely NAT here. No special heroic efforts/config file changes. I've been to a few locations where the phone wasn't able to connect to the t*f*t*p server but still managed to place and receive calls.

 

[jpe]

Put it in the peer section

dtmfmode=rfc2833

 

[vinod]

Ok. Now let me check with all kind of possibilities and come back.

Anyway thanks for everyone's help.


Vino

 

[vinod]

Im so near to it. Ok, Only might be a few things left to go.

The phone was once reachable when i modified some value and now it has jumped back.

To be very clear, let me tell what exactly the problem is.

My asterisk server is on a Public IP say xx.xx.xx.xx and on a different network.
My Cisco Phone is on a Private IP say yy.yy.yy.yy and on a different network.
Cisco phone shows my Broadband Static IP zz.zz.zz.zz on my asterisk server as the register contact.

Now what are the values should i use for the following?

nat_enable: ""
nat_address: ""
nat_received_processing: ""

These are the values that confuses me.

Please help me

Many Thanks
Vino

 

[jhamon]

Hi,

From my own settings I would say

nat_enable: "1"
nat_address: "zz.zz.zz.zz"
nat_received_processing: "1"

 

[vinod]

Solved. Its Working !!!!!!

There was a mistake in the SIPmacaddress.cnf file and i changed to suit it.

Im happy now it is working.

Thank you guys for your immense help.

Regards
Vino
