Station to Station calling on IpO to Legend

[bobertb]

I just saw my "Subject Line" Station to Station contains an inadvertent tribute to the late David Bowie

I replaced a Legend system that had 4 digit dialing to another Legend system in the same building.
Sales/Engineering missed this little tidbit and I found it on day of install.

I thought I had it working, but due to confusion, only tested it one direction. My Bad.

Not knowing Legend, it appears the incoming connection from the Legend is a Station Port.
You get dial tone from it and can dial extensions on the Legend.
It looked like on the Legend I was replacing, that incoming connection terminated on a Trunk appearing on a number of phones

Users on my side hit the Trunk button and dialed 4 digits to the other Legend.
Users on the other Legend just dialed a 4 digit extension from an Appearance key (Not sure what Legends have for "Appearance" Keys- I did not verify this on the Legend side)

So how I implemented this on IpO was:
[ul]
[li]Terminate incoming Legend Station Port (I think it was a station port) on to IpO Trunk Port.[/li]
[li]Assigned IpO Trunk to various phones[/li]
[/ul]
This worked nicely.
IpO user got dial tone from Legend and did 4 digit dialing.
I was ecstatic I got this working- BUT..didn't test Legend to IpO dialing

3 weeks later after the installation a call comes in complaining the Legend users can't dial the IpO- They just get ringing.
I go to site and find this:
[ul]
[li]With a Test Set on the Ipo Trunk port I hear "triple ring" coming from the Legend RING-RING-RING ... RING-RING-RING[/li]
[li]Call never Alerts on IpO Phones on the Trunk appearance key.[/li]
[li]IpO SSA shows some sort of State Change when the call first rings on the trunk but goes idle while the incoming call continues to ring.[/li]
[/ul]

Any trick I can use to get this to work?
I did NOT try connecting the Legend port to an IpO Station port because I didn't really what the characteristics of the Legend port were. Not sure how I could work with that setup?

The IPO is quite fussy about line and ring voltage, it's probably considerably lower than what's expected on a proper line and so it's not recognised correctly. I imagine the triple ring/odd cadence doesn't help either

Thanks amriddle01.
Any Legend techs out there that can think of a tweak on the Legend side. Trunk interface on the Legend with some tricky programming ??

I have done the opposite with a Partner ACS and it has been working fine for 8+ years so it is worth trying on the Legend. Partner line port to IPO station port. On the IPO they transfer to the station port which then rings the Partner line port. From the Partner they go off-hook on the line port and then just dial the extension on the IPO.

On the Legend, you might be able to classify the single line extension connecting to the IPO's trunk port as a Fax Extension, which will change the ringing cadence to a full ring instead of the triple ring.

Menu
SysProgram
Exit (or Start for Magix)
AuxEquip
Fax
Extension
Dial the extension number of the single line port
Enter


If you really want to go down the rabbit hole, you might be able to use a TRUNK port on the Legend to a single line STATION port on the IPO, them implement Uniform Dialing Plan on the Legend, where you tell the Legend which extension numbers reside on the IPO, and when a Legend user dials them, which trunk to access and what digits to dial.. Otherwise, you could put the Legend trunk in its own pool, change the pool number to something like "5", give everyone pool dial out code access to it, then they would dial 5 and the IPO extension number to get to IPO extensions directly.

Thanks guys...
Your ideas definitely give me something to work with.
