Hi
I want to setup basic Sip trunk with Service provider on my CME. There would be no authentication required for the sip trunk configuration, as per the service provider.
In the configuration on CME, do I need to configure the sip-ua OR do i only conifgure the dial-peer with session target pointing to SIP server.
Please suggest.
Thanks,

In the configuration, there is sip-ua configured with authentication option. In case, there is no authentication, is the sip-ua still required to be conifgured on the cme?

If you do not need authentication just don't configure that line.
I assume your telco provided a registrar server config so that you need to configure.

What exactly does the sip-ua configuration provide... it provide the e.164 number registration with the registrar server? Do i need it in my case, where I need to send the calls to and receive calls from the Service Provider.

sip-ua configured a SIP User Agent. It's essentially used if you need to have the router act as a User Agent instead of a SIP proxy. So for an instance where you need registration. We do sandwich some global SIP configurations in here instead of 'voice service voip/sip' from time-to-time, though.
For your scenario, sip-ua is likely not necessary.

To put it in a simple answer: if your SP doesn't require registration, you likekly don't need to configure a sip-ua at all. You'll probably be okay with just a SIP dial-peer pointing to the destination.
If in doubt, and something isn't working as intended, run 'debug ccsip mess' and see what's happening between CME and the provider.

Hi
For the Sip trunk with the Service Provider on CME, you can directly configure the SIP Routing and there is no need of authentication using sip-ua.
Router CME #
voice service voip
sip
bind control source-interface FastEthernet0/1
!
voice class codec 1
codec preference 1 g729r8
codec preference 2 g729br8
!
dial-peer voice 25 voip
description sip turnk sp
destination-pattern 2978
session protocol sipv2
session target ipv4:128.16.67.5
incoming called-number .T
voice-class codec 1
no vad
!
This configuration will help you to enable the SIP Trunk with the Service Provider IP.
Pl rate if this helps you.. thankz
