Service Provider Selection for Outbound Calls

(1/2) > >>

KevKan:
Am I on the right track or have I missed something?   Will it work?

ObiHai 202 with SP1 = ITSP “A”, the provider of e911 service
                      SP2 = GV Number
                      SP3 = ITSP “B”

Desired outbound call routing: 911 calls would go out on SP1, all other calls on SP2 and if it’s busy, SP1, and if it’s busy, SP3
 
I have Enabled Trunk Group 1, with TrunkList = sp2,sp1,sp3,pp

Outbound Call Route for bothPort 1 & Port 2:
    {911:sp1},{([1-9]x?*(Mpli)):pp},{(<##:>):li},{(<#:>):ph2},{(<**70:>(Mli)):li},{(<**82:>
    (Mbt2)):bt2},{(<**81:>(Mbt)):bt},{(<**8:>(Mbt)):bt},{**0:aa},{***:aa2},{(<**1:>
    (Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**3:>(Msp3)):sp3},{(<**4:>(Msp4)):sp4},{(<**9:>
    (Mpp)):pp},{(Mpli):pli}

Service Providers -> ITSP Profile A General -> DigitMap:
(1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|011xx.S3)

Service Providers -> ITSP Profile B General -> DigitMap:
(911|1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|011xx.S3)

Service Providers -> ITSP Profile C General -> DigitMap:
(1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|011xx.S3)

Voice Services -> SP1 and SP2 Service: X_NoRegNoCall: Checked

Voice Services -> SP1, SP2 and SP3 Service: MaxSessions: 4

Voice Services -> Gateways and TGs -> Trunk Group 1
Trunk List: sp2,sp1,sp3
DigitMap: (Msp2)

Physical Interfaces -> Phone1/2 Port -> Primary Line: Trunk Group 1

Physical Interfaces -> Phone1/2 Port -> OutboundCallRoute: Set to default

If the dialed number matches the TG1 DigitMap, it will be processed by the TG.
If number doesn't match SP2 DigitMap or the call fails, the TG will try SP1.
Same for SP1 and the call will go to SP3.

911 will not match SP2 DigitMap, so the TG will bypass SP2 and try SP1.
You don't need to modify the outbound route for 911.

If the SP is down, the TG will wait approx 30 seconds before trying the next trunk.
X_NoRegNoCall will eliminate the wait.

Thanks azrobert! This is the closest situation to my specific search of information. Could you, please, help me to configure OBI200 device the way mentioned here: http://www.obitalk.com/forum/index.php?topic=16270.0  I would really appreciate your time!

KevKan:
Thanks azrobert for providing me the solution.  I am now in the process of making the changes you suggested.

KevKan:
azrobert. I sent you a PM on this subject.
