Hello Experts,

Please guide me how can I enable the above ports on my cisco 2911 route

Hello Raj,

do you have a voice card installed in your 2911 ? Not sure what you mean by enabling SIP and RTP ports - no ports are blocked  unless you configured access lists or some sort of firewalling. Can you post the config of your 2911, as well as the output of 'sh version' (so we can see what you have on the router) ?

Hello Georg Pauwen,

I don't know exactly about voice card installed or not. Here no one is there to support me, I am only person in this Company.

% Password expiration warning.
-----------------------------------------------------------------------

Cisco Router and Security Device Manager (SDM) is installed on this device and
it provides the default username "cisco" for one-time use. If you have already
used the username "cisco" to login to the router and your IOS image supports the
"one-time" user option, then this username has already expired. You will not be
able to login to the router with this username after you exit this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to
use.

Post the complete output to the command "sh inventory".  If there is a dialer card it ain't going to work because the UC license feature set is not enabled.

Hi raj@nextweb.com.au,

Check the ISP modem you connect to Cisco2911 is there any firewall feature enabled? If yes then disable that firewall feature.

Spooster IT Services Team

Hello Spooster IT service,

How can I check the ISP modem? is there any command ?

where I will check firewall feature enabled or not?

We don't have any firewalls but in my configuration I had one accesslist:

access-list 20 permit 192.168.1.0 0.0.0.255(if I am removing this accesslist internet is not working)

exactly what happened is with out cisco router I tried directly ISP connection to my laptop it is working fine but whenever through cisco 2911 router to my laptop it is not working(soft phone is not registered to SIP provider)

They said something is blocked on your router, and also they said create the rules and please allow the ports LAN to WAN & WAN to LAN.(I don't know how to allow)

They said no need of ip route then how to resolve this problem?I have only basic static configuration on my router.

I know this is because of my router configuration only but I didn't find out exact cause.

this problem effected on my job purely.

Regards,

Raj

Hi Raj, 

There are multiple subnets running on your network. There are four interfaces that you had ip addresses assigned. Can you let me know which interface is used for what? And also in which subnet your soft phones are?

Spooster IT Services Team

I am waiting for your reply please.,.

I think in my router configuration, access lists is configured

access-list 20 permit 192.168.1.0 0.0.0.255

Please tell me what to do now, I waiting for your response 

Georg please reply me.,,.

I am facing the issue with By using Cisco 2911 router soft phone(zoiper) is not registered to SIP provider.

soft phone(zoiper) is working fine for with out cisco router I tried directly ISP connection to my laptop it is working fine but whenever through cisco 2911 router to my laptop it is not working(soft phone is not registered to SIP provider)

I am getting these 2 errors

SIP 503- Transport failure: no transports left to try

SIP 408 - Request timeout

but by using normal broad band it is working fine.

We don't have any firewalls but in my configuration I had one accesslist:

access-list 20 permit 192.168.1.0 0.0.0.255(if I am removing this accesslist internet is not working)

Hello,

I haven't followed the entire thread, but do you have:

ip forward-protocol udp 5060
ip forward-protocol udp 5061
ip forward-protocol udp 5070

enabled globally on your router ?

Router#conf t
Router(config)#ip forward-protocol udp 5060
Router(config)#ip forward-protocol udp 5061
Router(config)#ip forward-protocol udp 5070

Leo Laohoo

Hall of Fame
no ip nat service sip tcp port 5060
no ip nat service sip udp port 5060

Are you talking about ALG?  By default, ALG is enabled on all Cisco routers.  Above commands are to disable ALG. 

Hello Leo Laohoo,

Thank you Sir for your reply.

Exactly what happened is last week we purchased one dialer and voip minutes from local service provider. For that they are installed zoiper soft phone on my laptop, at that time they are trying to register our account on 5060 port but that is not register.

for that one they said SIP and RTP ports are not opened, so at that time I contacted  my Internet service provided(ISP). They said for my end we are enabled but you need to enable your end for allow the traffic like that they said.

One more point is by using Different network(broad band) zoiper is able to register and we are able to make a calls. Whenever I am switching the leased line which is configured on cisco 2911 router the zoiper soft phone is not registered.

By ISP end they are sent screen shots by using PING.EU website, port check--for them that is showing the port is opened but at the same way I tried for me it is showing port is closed.

Please find the attached screen shot, for them that is showing opened but for me it is showing closed. So that's why I am asking how to enable the SIP ports on my end and how to resolve the issue?

Regards,

Raj

ip nat service sip tcp port 5060
ip nat service sip udp port 5060

Try these two commands and see if they improve things.
