secondary dial tone to avaya extension (gateway 2921)

[asotojimenezz]

Hi

I have a sip gateway 2921.

PSTN calls made by dialing 9

Now I need to integrate the gateway to Avaya.  As I make to call Avaya extensions with the number 8 as the output tone Avaya extensions.

The integration will be through 4 FXO ports on the gateway and a module with FXO ports side Avaya.

It works ?? prefixing the number 8 in the destination pattern.

Regards.

Hi,

I would request you to explain the question in detail. 

From the above if I understand it correctly you want to add access code 8 before every PSTN/External number and want to strip the number 8 on the 2921 gateway before the call is been send on the FXO port.

This is achievable. Kindly send me the running configuration of the gateway and also a test number that you'll be dialing out.

Please feel free to contact me.

Thanks and Regards

Hello Akshay

You explained it in detail

I have two scenarios:

1. users dial the number 9 to exit to the PSTN (works, this is maintained)

2. now the gateway 2921 to integrate Avaya through fxo ports. Need to dial extensions cisco Avaya extensions but for this prefixing the number 8 before extensions Avaya.

Example.

Cisco 100-200 extensions
Avaya extensions 200-300

The extension 120 (cisco) calls the extension 220 (Avaya) but prefix number 8 before dialing the extension 220.

Dialed digits 8220

9 to the PSTN is maintained and the number 8 for the Avaya call extensions from extensions (cisco)

Number 8 would like to get a dial tone before calling Avaya extensions

This is possible?

Hi,

Can you please tell me where are the Cisco Extensions registered. Is it a CME or a Avaya server?

If it's a CME then following would do the trick:

telephony-service

secondary dial-tone 9

If it's a CUCM server then you would have a route pattern for Avaya extensions. Over there you have a option known as "Provide outside dial-tone", please check that.

If the Cisco IP phones are registered to AVAYA server, there's nothing a cisco router can do . It has to be configured in the AVAYA server.

Thanks and Regards

Please note that to connect two devices using analog ports, one device should use FXO and other FXS. In your first post, you've mentioned that both Cisco gateway and Avaya will use FXO port to connect. If that is the case, such integration won't be possible.

I further assume that you will use say FXO at Cisco side and FXS in Avaya to connect. Now to route the call from Cisco to Avaya, you just need to have dial-peer like below;

dial-peer voice 1 pots

  destination-pattern 8[23]..$

  port x/y/z

Now when Cisco user dials the number say 8220, Cisco will off-hook the respective FXO port and will get the dial tone from respective FXS port of Avaya. Gateway will dial 220 (8 will get stripped automatically) and Avaya will detect DTMF and will place the call to 220.

asotojimenezz,

Addition to what Vivek and Akshay said, you do not need to preform a prifix digit infront your dialed numbers to avaya system. you already have diffrant Cisco extention numbers and avaya extention numbers. which will be more easier to user to call and looks more profional. the...

dial-peer voice 1 pots

  destination-pattern [23]..$

  port x/y/z

also you can use trunkgroup inside your dialpeer which will includes all your 4-FXO ports.
