Sounds like you might need to reach out to the access provider?

Is this a new service that your just setting up, or an existing one that is having an issue?

The most common issue is setting the Number of Digits to Absorb setting, if you leave it blank it will fail for every inbound call, make sure to put a 0 in that field. (The online help states this as well)

Hi Guys,

Thanks for the feedback.
I have 0 in the absorb field.
Another question. Should i at least see inbound traffic in the ccs trace when i made an inbound call?

I am not getting any inbound traffic in the ccs trace. I am thinking maybe the provider is not sending the digits (inbound) towards the Mitel.

Regards,

Gimitel

Not if it isn't getting to call processing for come reason... Best to do an EDIT TRACE TSP L2L3 <PLID> and watch it when you make an incoming call.

Hi acejavelin,

I will do that tomorrow. What should i expect in the trace? If i am not getting anything does that means that the provider is not forwarding the calls the the Mitel switch?

Thanks,


Gimitel

It should be the raw Q.931 signaling messages... You should see output like shown in this thread: http://mitelforums.com/forum/index.php?topic=11493.msg51789#msg51789

The first thing I do in that situation is I try ringing from 3 different providers, because that's a very quick test - sometimes some providers fail to route while others route correctly.
 
If they all give the same result then you need to talk to your provider about whether they are routing calls to you.
 
You can even try on the new system to ring an internal number by dialling its full external number so that it routes out to the provider and loops back to see what happens.
 
*** If I am setting up a new service, I usually put in my test number to the DiD form in every format I know the provider might present it as - ie, in Australia 8 digits & 10 digits. That way I don't have to worry about whether the DID form is correct until after I am getting successful calls.

Hi Acejavelin,

I did use the command  EDIT TRACE TSP L2L3 <PLID> but cannot see any inbound traffic when calling the DID number. Does this mean that the provider is not forwarding the call ?
Outbound call work oke.

Can someone advice please.

If you are not seeing any inbound Q931 messages, then I think at this point I would engage the vendor... They should be able to trace the call and see what is wrong and either fix it or point you in the right direction.
