While I do work in industry I am after picking someone’s brain as to a solution I am being asked to provide. While I have what I think is the answer, without prior knowledge of the product I was wondering if anyone had come across using the same or similar:

Client requires:

Inbound SIP trunk to terminate over PSTN and ISDN BRI(and PRI at a later stage) simlutaneously

Thinking of using a Patton hardware but never used it before and after knowledge/recommendations if any can be provided. Thanks

A Cirpack Softwswitch might support ISDN in parallel with POTs.

See: http://www.ato.sk/docs/Cirpack_NGN.pdf

😯
I understood many of the words, but the order they were placed in made no sense whatsoever! Does this win ‘Niche Subject Of The Year’ award?

Thanks footflaps, while a softswitch may well have the ability to do what I want, I think that may well be a case of taking a Nuke to a fist fight.

I’ve found some standalone gateways which can do either (BRI or FXO(pots)) I still don’t have a combined solution unless I spec way above costing more than the price of the two individual gateways.

Settled on Sangoma Vega’s at the moment rather than the Patton due to the advanced GUI based config which my client would much prefer to a CLI based product.

Count, it may well be ‘NSOTY’ but based on some of the stuff I read on here I doubt it. Horses for courses as its not actually that niche for me, just different. I thought my days of playing with TDM kit was well over.

You’d be amazed how much is still in use, most mobile networks are still 90% based on E1s.

Why ?
Thats the question I’d ask.

Why ?

1. It works.
2. The networks cost billions to roll out, so it’s not a simple fix.

In the UK alone there are something like 50k Macro cell sites.

It will all get swapped out to Ethernet RANs when they do a network re-fresh eg I’ve seen a few London Macro sites get refreshed recently, but it’s a big change. The six cabinets of 48U and massive power supply with 500Kg of Lead acid batteries, for standby power, all get replaced with a shoe box size modern multi-mode BTS, supporting 2G, 3G and LTE and a tiny PSU.

No not why to you but the original poster. I’ve worked on enough transmission systems in 30 years to know how they are put together.

If you through-patch a GFND connection into the internal trunking system you’ll find it a lot easier to sync with any SMT-based clients.

Email in profile if you want any more details.

Why….as I have been asked by a long term friend to provide this solution…he is currently in South America and wants to route wholesale traffic via the methods above…..and without going bananas in the cost department too.

Grum…I don’t even know what a GFND and SMT based client is.

Well that explains a lot, but sorry cant help as I guess there are a 1001 solutions out there for what he wants. May be worthwile looking at his SP to see what kit they use for the IF to the PSTN. Always a good idea to match manufacturers as when it comes to fault finding one will say its not our switch, the other saying its not our terminal kit.

I’ve already asked him to source the adapters as I will present RJ-11 fly leads out of the gateway and I know they don’t use RJ-11 out there as its some mad two pin plug.

Already spoken to manufacturer of gateway and they have no issues with their kit working down in Latin America although they are not sure if anyone has tried to do this in Venezuela.

Good luck 🙂

Oh this takes me back to my previous job.

BT….HP….

Shoot me.

There are middlemen that can do this sort of stuff in the cloud. Might be something you want to look at? I’ve got a few names of companies if you’re interested.

Thanks Dales! Think I’ll need it.

Swedishmatt, the whole point of this is to undercut anything else available. I know plenty of wholesalers/carriers who I could give the traffic to and we all make a little money.

Grum…I don’t even know what a GFND and SMT based client is.

Probably because I made them up. Just wanted to join in with the techno-babble. 🙂

Would an MD110 suit your needs?

We have our incoming lines on an E1, internally we have pots lines, ip lines, and digital lines depending on LIM configuration. Once it’s up and running config via extension and directory manager is fairly straightforward. (Please excuse me if you know this already)

It’s also trunked to our CUCM as we are in a process of migrating, but that would be a 2 box solution for you as you’d need a gateway to provide pots.

Hi mate. Work for a specialist VoIP network provider as it happens. Before going into VoIP 6 years ago we were (and still are) a software development house for the Comms industry building back-end stuff to connect different networks together (as I understand it). We’ve done a load of stuff for the likes of BT, Vodafone and Cable&Wireless. That said I am the commercial guy, not the technical end, but I do work with guys who’ve spent the last 20 or so years building networks and designing software to make things talk to each other and the outside world. Happy to put you in touch with some of those guys for a chat if that would help. Email me on ben@pack-net.co.uk if that’s of interest and we’ll see what we can do to assist

mrLugz, an MD110 would no doubt work, however this is not a commercial deployment, this is a grey market bypass route intended to be deployed on site in minutes and can at worst case be thrown away/removed without too much of a loss to the business….ROI should be no more than 2 weeks for each deployment.

I’ve ordered one of each of the following;

Sangoma Vega 50: 1 x 4 BRI and 1 x 4 FXO

The key to this is being able to rapidly deploy anything from a couple to a couple hundred and not have the interoperability issues between Gateways and SP’s. From speaking to the Manufacturer of these boxes I am happy I’ve found what we need for the testing phase.

I just hope I can tunnel in/out of Venezuela without too much issue 😯
