What is my problem? I need your help

Can you give me some cofiguration like this, if you have ?

Thank you

You do not need to define registar, etc between 2 CME systems, all you need to do is have the dial-peers and add the following global commands on both sides:

voice service voip

no ip address trusted authenticate

allow-connections sip to sip

HTH,

Chris

YASITAERICK · ‎02-06-2012

but I want to configure two sip gateways, and with command

registrar ipv4:190.100.101.2:5060 expires 3600 is necessary to register all points like fxs right?? And I don't have this comand

allow-connections sip to sip.

Are there any command to replace this?

Chris Deren · ‎02-06-2012

No, nor do I think you could do this. The only reason you would want to do this is for integration to SIP trunk provider. All you are doing is simply integrating 2 CME systems, again all you need is dial-peers on both sides pointing to each other and global "allow-connections sip to sip" which allows IP-IP GW connectivity.

HTH, please rate all useful posts!

Chris

YASITAERICK · ‎02-06-2012

well, I'm doing that demo in router 2801? But I have to realize this in AS5350. This is a getway so I want to integrate that gateway to other gateway (NET2PHONE). In this gateway there isn't that command what can I do?

thank you for your interest

YASITAERICK · ‎02-06-2012

I need registrar: because I want to register with a provider:

registrar {dns:address | ipv4:destination-address}[expires seconds][tcp][secondary]:Allows a gateway to register the E.164 numbers of non-SIP phones with a registrar or proxy server.

With that command I 'm to register my FXS rigth??

Chris Deren · ‎02-06-2012

Do you have a SIP trunk service from your provider? If not there is nothing you can register.

Chris

YASITAERICK · ‎02-06-2012

Are you ther

Chris??

YASITAERICK · ‎02-06-2012

So, with this command

registrar

Can I register my fxs to make call or Isn't necesary realize this when I configure like this toplogy ?? I tried to simulate that

ok.

YASITAERICK · ‎02-06-2012

What is the correct configuration I need only dial peers ?

Chris Deren · ‎02-06-2012

Simply having the "session target ipv4" pointing to the other side is what makes it work, also make sure you bind SIP protocol the IP address.

As to your 5350 GW are you saying you cannot enter the global allow command? What IOS are you running?

Chris

YASITAERICK · ‎02-06-2012

I have that ios in the AS 5350

c5350-jk9s-mz.124-15.T15.bin

YASITAERICK · ‎02-06-2012

to produce like singanling in the two gateway. I need only put that right.

Yes, I tried to put the command allow-conn... sip to sip but in this IOS that command doesn't exist. There are other command that replace ???
