Tie trunk between two Avaya PBX's - CSU hardware required? 2

[PhonesAllDay]

Hi I have a question on setting up 4-digit dialing and calls between two Avaya sites.

There is an existing data link between both sites as I can access ASA to both PBX's from the main site, also call accounting is logging both sites.

The main and remote site are both R11.

I tried to add an H.323 trunk to the main site and it did not allow me. (Is this because there is a single CLAN card in use for other purposes or an RTU license needed?)

I am able to add an ISDN tie line with H.323 signalling from the main site and questioned if that is the best way and if a CSU is still needed if connecting directly from a DS1 to the Data switch?

Thank you,

Ok....display system-parameters customer-options - that'll tell you if you have H323 trunks permitted.
Secondly, you need CLANs for signalling and Medpros to carry the voip if you use H323. Thing is, in administration, its considered trunk type ISDN and carrier medium h323 for voip as ISDN and H323 are pretty much the same with the add-on that you're using IP packets in H323.

So, unless you can wire a TN464 from one switch to the other, you're best bet would be voip, and if you don't have that licensed, then maybe some cheap PRI/SIP gateways - PRI from each switch to an Audiocodes Mediant 1k for example, configure SIP between those 2 Mediants over your WAN and just talk normal PRI between your Avaya systems to the SIP gateways.
Heck, you could probably do it with cheaper SIP analog gateways.

Again, that's all dependent on how remote your remote site is - wire up a PRI, no CSU required (most likely...what DS1 cards are you using?), otherwise, barring you having paid for voip at the time or having IP phones, you probably wouldn't have voip enabled on the system due to the cost at the time.

Hi, DS1 board types are TN2313, TN2313AP, TN767E
VoIP, probably not enabled. There are no MedPro cards and just one CLAN for call accounting. Thank you for your advice.

I don't think any H.323 trunks are in the customer options:

You should be able to tie two TN767s together - but how close/far are your local/remote sites?

 

[PhonesAllDay]

Far away, probably 2,000 miles...

 

[Mitch672]

with that distance, and without IP enabled switches (and only DS1 cards) your going to need a solution that can take a T1/PRI in, and convert it to SIP/H323 trunks, and transport it across the internet, you might need a VPN appliance as well on each end. you can't connect T1 cards accross 2,000 miles directly.

You might be over-complicating this issue. If you have 2 systems that are compatible and you have DS1 boards, your simplest and easiest option is ordering a point-to-point T-1. You can get any LEC to build one from state to state and all you need is DS1 boards on both ends. I recommend you get PRI's so you have d-channels and can run traces, etc. Turned these up several times, pretty simple.

If you don't want to do that, then you're back to needing the correct software packages, CLAN's for call control and Medpro's for audio resources. Not cheap to get all this done but might be a quick ROI depending on your call patterns/frequency.

Thanks Voice99, The remote site is in another Country so point to point T1 would not be so simple given the limited carrier options and expense on the remote side.
