Do I really need VPN or MPLS

Anupam Singh · ‎08-22-2014

I have got two offices named Office A and Office B. Office A is using Cisco 2911 Router having trunk lines in it. Cisco 7960 IP phones running Sip firmware registered with this cisco 2911 router using CUCME. The Office B is using non cisco IP PBX registrar server and its own IP Phones. I would Like to connect this non CIsco IP PBX with Office A Cisco 2911 Router using VoIP Trunk.

I want to create VoIP trunk from office B to Office A so that B can connect with Cisco 2911 router trunk lines and local extensions. Peering SIP trunk between Router A and B would be enough or I need to register SIP trunk using authentication credentials.

Actually main aim of this project is to access Office A analog trunk lines (cisco router) from Office B.

Can Anyone suggest outline concept for doing this please.

Thank You

Hi Anupam,

It basically depends upon your non Cisco PBX if it really wants the SIP trunk to be authenticated or not.

In most cases, there won't be a need to register the SIP trunk. All you will have to do is to setup dial peers and have connectivity between the two offices.

HTH,

H Nipun,

Thanks for your suggestion.

I have both options on non cisco PBX. If I craete peer from non cisco router to cisco router then do I need to peer with public IP of Cisco router? As I have public ip on dialer 0 interface of cisco router.

Non Cisco PBX is connected with dsl broadband router. port is forwarded to the pbx from dsl router.

Can I do port forwarding on Cisco router from dialer0 interface to the port where all phones are registered?

Thank You

Can anyone please suggest outline configuration needed to call from one office extension to another office extension using voice over IP calls?

Dude,

This forum is not about outline configurations, you will need to do the hard yards. We will point you in the right direction. You can post what you have so far, and we will help you making it work. Now you asked about public v private IP addressing on your 2911. really it doesnt matter what you use as the source/destination IP address, as long as there is connectivity. from and to your 3rd party PBX.

post your config.

Im Sorry for not posting all details. Please find configurations on Cisco Router below.

I did connectivity between Cisco PBX and Non Cisco PBX by creating dial peers. Do you want me this dial peer configuration both side or WAN connectivity i.e. I should be able to ping both sides public ip?

The configurations are as follows:

Do I really need VPN or MPLS between two sites? As I have got static public ip both sites to peer ip pbx using dial peers.

I am able to peer two PBX now but I would like to use each others trunk connections. Is this possible in peering two PBX or I need to make pbx registrar server and register pbx with each other?

Please suggest me guys. Any type of suggestion is most welcome.

Regards

How can I use Cisco 2911 router as a sip proxy server to register as a trunk provider from remote site IP PBX
