CURRENT NIGHTMARE: IP Office to Ericsson MD110 H.323 link

[dadz]

Once again I've found myself up a creek sans paddle.

QUESTION: How do I go about connecting these two (2) beasts?
The IPO is a 500v2 Rls 7, the MD110 is 1,000s of miles away.

I know very little about the IPO and need guidance with setting up an IP link to the Ericsson. The Ericsson has already been configured to use H.323 trunks.

HELP!!!!

P.S.
Local assistance is not readily available for the IPO.

 

[hairlessupportmonkey]

H323 trunk, IP routes, Shortcodes, and voice networking licence on the IPO.

so

1) Do you have the licences installed?
2) What networking do you intend to use between sites.
3) Should you employ an IPO contractor to help?
4) many more variables.

The vendor is of little to no help in this regard.

There seems to be some amount of confusion as whether Voice Networking Licenses are actually required etc.

To make things worse another tech I've consulted claims that it is not possible to link those systems via H.323. The original idea was to do so via the internet.

Has anyone here ever done, or heard of this being done?

Voice networking licences are most definatley required, whoever says they aren't does not know jack shit about the system. The IPO can do H323 and you say the other kit does, some form of link should be possible but you would need a VPN or similar in place first, linking directly over the net will not work

This sounds like such a bother to setup! I may have to convince the remote side to configure for SIP.

 

[dadz]

But just for the heck of it, do you know of anyone that has actually gotten these two systems to talk to each other?

I'd love to get my hands on the configurations used.

nothing been mentioned here

SIP will require SIP trunk licences on the IPO.

It always used to be a real PITA to connect H323 to a MD110. I believe that you have do something wierd like QSIG to a smaller ericcson switch (BC10) and then from there use H323. I suspect that in this day and age the MD110 will do H323 natively, but will require the appropriate cards and licences.

>The original idea was to do so via the internet.


I find this a bit of a laugh really - You have an enterprise class PABX and a SME switch that you wish to interconnect. Lets connect them over a medium that doesn't permit class of service and has no service level! Sounds like a system designed by someone without a clue.

My wish has come true. I no longer know how to use my telephone.

 

[dadz]

Hey Matt, thanks for the info. But are you saying that it wouldn't work even if connected via VPN?

 

[hairlessupportmonkey]

no QoS over a vpn either....

a managed leased line / mpls with QoS of some description would be your better option.

> wouldn't work

I am sure that with a VPN you will be able to get the 2 systems to connect to one another (assuming you have an MD110 that will do H323 natively or a BC10 that hands off to it and appropriate licences) What I query is how well it will "work", in that any speech will be subject to all sorts of disturbances in the internet. Isuspect that your users will expect carrier voice quality and will be disappointed when they get all sorts of issues because the transit network is not suited to it.

As HSM says a leased line or MPLS woudl be a much better bet.

Situation update, and new issue.

I've got the IPO and the MD110 communicating with each other via H.323 (yaaay!).

Here's the new issue.
The IPO has a 4 digit dialplan, and the Ericsson has a 6 digit one.
How do I get the IPO to pad the calling number information sent to the MD110?
I need to add 2 digits to the calling extension's number.
Format: XX1234.

NOTE: Changing the IPO to a 6 digit dialplan is NOT an option.

 

[mattKnight]

Add a shotcode in theARS that points to the trunk to the MD110

SC - XXXXXX
TN - NS34E
feat - dial
Lg - IP trunk

Where 34 is the prefix you wish to use

Does using an uppercase "S" make a difference as compared to a lowercase one?
