VG200 & Option 61 Integration

Does anyone have a working config for a VG200 connecting to a Nortel Meridian Option 61 via T1/PRI (NM-HDV)?

I appreciate any help you can provide.

Thanks.

Re: VG200 & Option 61 Integration

The config below works like a charm. As far as I know it is the only config that works with Nortel Meridian 1s - the Meridians seem to be fairly picky about how they route different switch types. The main trick is to set the gateway up as switch type DMS 100, user side, and the Meridian 1 as switch type SL-100, network side.

On the IOS gateway:

isdn switch-type primary-dms100

controller T1 1/0

framing esf

clock source line primary

linecode b8zs

pri-group timeslots 1-24

!

!

interface Serial1/0:23

isdn switch-type primary-dms100

isdn incoming-voice voice

isdn flip-chan-flag

!

!If on earlier version of IOS (12.1.x)

!isdn tei-negotiation first-call

!

-------------------------------------------------------------------------------------------

Nortel Meridian Option X

1) Meridian 81c using NI2 Network side will only process the last 4-5 digits of any number, so tandeming to the PSTN is not possible (in fact, if the last 4-5 digits of the number sent out match a PBX phone extension that phone will ring).

2) Set Meridian PRI to S100 Network side if software allows. Successful integrations seem to be running version 22 or later on the Meridian.

3) Must set "S100" on the trunk group (RDB) and on the D-channel config. They can then set the PBX for network side.

4) Set VG200 for DMS100 User side. Caller name should work with IOS 12.2(5)+

5) Make sure PBX tech downloads MSDL channel if D channel does not come up. IMPORTANT!

6) PBX tech will also have to make sure correct parameters are set to pass calls from his PRI to CallManager to PRI on PSTN (NCOS, TGAR, others)

Here is some pertinent config info from a Meridian PBX that is

working with the above PRI

On the D-Channel:

CTYP MSDL

CNEG 1

RLS ID **

RCAP ND2

On a trunk (ds0)

TYPE TIE

CDEN SD

CUST 0

TRK PRI

PDCA 1

PCML MU

NCOS 2 <<< Depends on permissions in switch

RTMB 79 1

B-CHANNEL SIGNALING

TGAR 1 <<< Routing code. Could be different.

AST NO

IAPG 0

CLS CTD DTN and so on <<< Per Customer should be UNR not CTD

TKID

FCAR NO

On the trunk route:

TKTP TIE

ESN NO

CNVT NO

SAT NO

RCLS EXT

DTRK YES

DGTP PRI

ISDN YES

MODE PRA

IFC S100

SBN 0

DSEL 3VCE <<< also works as VOD

PTYP PRI

AUTO NO

DNIS NO

ICOG IAO

SRCH RRB <<< Can be set to LIN (linear hunt)

TRMB YES

STEP

ACOD 7979

TCPP NO

TARG 01

CLEN 1

BILN NO

OABS

IDC NO

DCNO 0 *

Re: VG200 & Option 61 Integration

Don,

I would like to know if you have come across these problems in a VG200 to Meridian T1 PRI link:

1. When the receptionist attached to the PBX transfers an external call to an IP phone linked via the T1 PRI link, the CLID that appears on the IP phone display is 'Attendant' instead of the original CLID.

2. The transfer is not clean. The receptionist has to press the 'release' key a couple of times before the call is transferred.

Not sure where in the PBX config this can be fixed...

Thanks,

Flavian
