PRI-A access over VoIP 1

PROBLEM / QUESTION:

On system A, when the PRI is full (pressing intercom + 9 = No Free Lines), I would like staff to have the ability to press ‘8’
and grab a PRI trunk (channel) from System B. (Easy, or so I thought!). So I did the following:

On System A

(the one I want to dial 8 on)
- Built a DEST CODE 8 (normal schedule and [highlight #FF99FF]absorb = none[/highlight])assigned it to use Route 008
- Built Route 008 as – External # = Blank, Pool = O, DN Type = Private.
- Put both Pool 0 and PRI-A in Remote Package 01 and made sure all my VoIP trunks had Pool o assigned
as well as PRI-A and that there were no other lines/pool in Package 01.

On System B

- Built a DEST CODE 8 (normal schedule and [highlight #FF99FF]absorb = ALL[/highlight] ) use Route 008
- Built Route 008 as – External # = Blank, Pool = PRI-A, DN Type = Public.
- Put both Pool 0 and PRI-A in Remote Package 01 and made sure all my VoIP trunks had Pool O as well are PRI-A
and that no other lines or Pools were in Package 01

I now get the following error:

I get "No Route to Dest" each time I dial 8, 416 on System A.
(right after dial the 4th digit is pressed, I get this error).

I’ve tried to play with the absorb lengths on both sides.. to no avail, it didn'twork.

So then went and did this:

On System A went to:
IP Telephony -> IP Trunks -> H.323 Trunks -> Remote Gateway
and added an '8' to the destination digits of the B system remote gateway entry.

Now, this at least got the 2nd switch, seizes a channel on PRI, but only passed the 416 to the PSTN, nothing past that.
(I then get the carriers default incomplete dial number msg)

(I'm using BCM Monitor on both systems to watch the traffic)

I was initially thinking that I could do this all with out
the need to add an '8' to the Remote Gateway programming
and that this was all achievable via Dest Code's and Routes.

I'm thinking the reason with adding 8 to the Remote Gateway
programming gets me a line out w/416 only is the private DN
length is 4, and it clips 8 and pass 416 and that's all she
wrote cause it thinks it a private DN call.. not a public to-be-routed call.

(Also, there are no access code/ line pool codes programmed
with / for 8 use on both systems)

Please, any insight to what I’ve don’t wrong would be great!

(sigh .. i'm, so lost here!)

Below is my config for the two switches in question. The both sit side-by-side.

We have 3 other switches on the VoIP network in other regional offices. (just for a complete picture) and we 4 digit dial the regional offices. (private DN lenght = 4
and all systems have been configes for 4 digit DN's)

Switch Config
==============

System A Has:
1 x PRI with all inbound telephone numbers programmed to the PRI
Centralized Voice mail
VoIP Trunking lines
Digital & IP sets (DN range 2100 to 2500)
VoIP Trunks in POOL O
Remote Access Package 01 assigned to PRI-A & PooL O only
Remote Access Package 01 contains PRI-A & Pool O only

When a call comes in to switchboard and needs to be transferred to a DN on system B, reception transfers the call to that DN, and it gets from A to B via VoIP trunks.


System B Has:
1xPRI that at the moment is used for dial out only
Digital & IP sets (DN range 2600 to 2800)
VoIP Trunks in POOL O
Remote Access Package 01 assigned to PRI-A & PooL O only
Remote Access Package 01 contains PRI-A & Pool O only

(system C , D, E are all in branch offices, this 2 ‘tie’ system is in our Toronto office)
DN’s on C=4xxx, D=5xxx, E=6xxx

In System A,Change route 8 to public instead of private.In public numbering plan define digit 8 as 11 digits to allow only local calls from system B if call is coming from system A.11 digits because it had to add the digit 8.
 
Hey VAPPL!
Thanks soooo much! This did the job! It was just the case of
setting the route 9 on A to public! Man, talk about whacking
my head against the wall! Thanks so much!
