Any suggestions ?

Available options for the two settings similiar to the one identified are as follows:

admin> set send-dnis-type-of-number?
send-dnis-type-of-number:
 Type of Number to be sent in called party IE in the setup message to
 pstn. For ISDN signaling. To be used on egress gateway for VoIP calls.
Enumerated field, values:
 unknown:
 international:
 national:
 network-spec:
 subscriber:
 abbreviated:
 transparent:  Setting this, we can pass TON transparently as received from
     upper layers or in case of VoIP, as received from Near End gateway.

admin> set send-dnis-numbering-plan?
send-dnis-numbering-plan:

 pstn. For ISDN signaling. To be used on egress gateway for VoIP calls.
Enumerated field, values:

We are providing voip services, these 911 calls are going out from our
subscribers to the lec to be delivered to the 911 PSAP..   Would this apply
in that scenario ?

Joe,

I am not sure if your 911 call is incoming or outgoing on PRIs.
#assume you have a T1 in {1 1 1}

Read t1 { 1 1 1}
Set line send-dnis-type-of-number ?

You will see options. Some 911 providers support media-before-connect. Plz
make sure your all of TNT support 183.

Hope it can help you

Alex..  would you point us in the right direction, or perhaps consider
sending a sample max tnt config reflecting how this is done?  Thank you..

I believe the ISDN call plan can be configured as part of the trunk
group / route.

Apparently, according to the carrier, all Special Access Numbers, 411, 611,
911, etc require this special code ???
