VoIP to VoIP hairpin with translation

[5276]

Is there a way to perform voip-to-voip hairpin in order to translate a called number? In other words, I want a voip dial-peer to match a specific dialed number, translate it, and then establish another call leg based upon the new translated number?

The real reason for this is a much longer story, but for the purpose of keeping this short I am excluding the details.

Right now I see the dial-peer get matched, I see the number get translated, but I never see another call leg. I was thinking about trying gatekeeper? Maybe this requires IP-IP GW services?

Let me know if you need more details...

I think the feature you are looking for is in the

IP-to-IP gateway IOS feature; this IOS feature set

allows for PSTN-to-IP gateway and the ability to

join two VoIP call legs.

I don't think that a single GK could work in the way

you described.

Another idea, though I have not used it for this

as IP-to-IP is what should probably be used, is if

you are using CME, is to try and use a "loopback DN"

that would perform translations for you; it's worth

the ten minutes of reading. . .

I got it working without the IP-IP GW code! It is pretty sweet, all done on one GW running CME. The loopback-dn idea was tried, but it doesn't force another call-leg (one in and another out), neither did a session-target ipv4:loopback.

Thanks for the response...

Ryan ,

And how did you do it on the CME , I want to try that solution as well to avoid the IP2IP gw

Well, I could tell you but then I would have to shoot you ;)

In all honesty, I cannot talk about configs for this install; this was for the 'red' side. Here is the best hint I can give you; CME will NOT route the same call twice, but if it thinks it is a different call, bam.

Sorry I have to be vague...
