IPO Call Routing Between Tie Trunks 1

[num025]

We're trying to traverse calls from IPO-1 to a Siemens PABX and vice versa. Those equipment have no direct connection between them but each has a tie trunk to a second IPO, where IPO-1 uses an IP tie trunk while the Siemens PABX uses an E1 connection. Users from a site should dial a specified prefix for a particular site along with the 4-digit extension in order to reach it. As a simple diagram:

IPO-1 (prefix 778) <- IP Tie Trunk -> IPO-2 (prefix 776) <- E1 Tie Trunk -> Siemens PABX (prefix 774)

We were successful for calls between IPO-1 and IPO-2 as well as between IPO-2 and Siemens, but we're having difficulties in sending calls to the Siemens PABX from IPO-1 via IPO-2. We're pretty sure it can be done, but we're really not familiar with manipulating numbers in IPO.

IPO1:
Shortcode
SC = 776XXX
TN = .
Feature = Dial
LineID = outgoing ID of TIE line to IPO2

SC = 774XXX
TN = .
Feature = Dial
LineID = outgoing ID of TIE line to IPO2

On TIE line shortcode:
SC = 778XXX
TN = N
Feature = Dial Extension
LineID = 0

IPO2:

Shortcodes
SC = 778XXX
TN = .
Feature = Dial
LineID = outgoing ID of TIE line to IPO1
SC = 774XXX
TN = .
Feature = Dial
LineID = outgoing ID of TIE line to Siemens

On TIE line to IPO 1 shortcode:
SC = 774XXX
TN = N
Feature = Dial
LineID = Outgoing LineID to the Siemens

On TIE line to Siemens
SC = 778XXX
TN = N
Feature = Dial
LineID = Outgoing LineID to IPO1

The siemens must send the number as : <access code>&extension, so to dial extension 221 on IPO 1 they dial 778221
I don't know if the siemens is capable of sending the extension numbers without the accesscode.

A simple mind delivers great solutions

Hey thanks a lot for this very helpful tip! I never realized you could mix X's and N's in shortcodes, I'll try this as soon as I get back to the site and will post an update here. Again thanks!

It's now working, although I did a simpler way by just using for example 778N for the SC then just N for the telephone number. Again, thanks for the help!
