CS1000 - Call Forward External - Desk 3904 to ATT CELL 2

[babytech2009]

I have a desk phone that has call forard external allowed
configured. When I have the user forward her desk phone
to a cell phone ( Verizon, Sprint) or home phone it fowards fine. However, when I have her forward to an
ATT cell phone I get "all circuits are busy 49".

I have been trying to reseach the error code but
to no avail.

I was wondering if it is a problem with the cell provider?
Or am I missing a configuration in the PBX that would limit
it to forward to ATT cell devices?

Any ideas?

1st hit the hard forward, when you get the telco message, call the same number from a phone and from a cell phone

We've run into a situation like this before but it was with Sprint/Qwest. Turns out that the two telco's involved did not have enough lines for the two to communicate reliably across in the cell tower facilities.. However ours was occasionaly a call would go through and that would be when a line cleared. Try dialing the number of the cell directly from a phone what do you get. If it rings sucessfully everytime then it is a different issue but I suspect its similar.

 

[babytech2009]

I have tried it from a cell and my desk phone when calling to her desk. I only receive the message when she is forwarded to an ATT device?

 

[bhassell2000]

sounds like an ATT issue to me

Thanks,

Buddy

 

[babytech2009]

I tried calling from my cell and desk no problem.
I am having the wireless tech question ATT what the error code means.

 

[babytech2009]

I think its ATT also Buddy.

 

[zigmo36]

Of course ATT will never admit it's their issue no matter what.

 

[babytech2009]

They never do its always our equipment never the circuit or the cell provider. I really dont worry about responsibilty. I just want it fixed. Not out to blame anyone.

The user is able to forward to other cell carrier devices and to her home. Just not to ATT wireless devices.

 

[allenmac]

If you are using PRI's for your inbound / outbound trunks, and you have NCRD set to 'Yes' in the route data block, try setting it to 'No'. Sometimes the carrier freak out if they see Call Redirection messages coming from the PBX.

 

[babytech2009]

Thanks Allenmac. I will take a look at that.
I created a ticket with ATT the carrier, to see if they
have any restrictions. So I can check that in the meantime.

 

[babytech2009]

ATT is doing a call trap on the circuit to see what happens when she fowards her desk to her cell.
They still think its the PBX in our field office.
They got all circuits are busy.
Keeping my fingers crossed.

 

[babytech2009]

I received att message from the tester.
Stating that it is Netowrk Unavailable Congestion.
Error #42 Switching Equipment. So its not even
leaving our PBX.
But it works when forwarded to home or other carrier
cell devices.

 

[allenmac]

Can you turn on D-Channel messaging and look at the D-channel messages that are being generated for this specific call?

You may need to test during low call volume hours in order to not get swamped with messages.

 

[babytech2009]

Yes I can? I may have to test with the person tomorrow.
She had left when I was testing with ATT.

 

[PERRYPJ]

So you verified you question that "All circuits are busy" tell ATT that it works fine with Sprint and Verizon and fix there trouble.

PerryPJ, I did tell ATT that. They stated when they did a call trap that it wasnt leaving our PBX. They got this
from the trap on both trunks.

Yeah I know its alot to look at. But this is what they sent.

ATT stated to do a call trace, so I am going to do that shortly from our pbx with the user.

 

[PERRYPJ]

It has to be leaving the switch if you are getting that recording, if it didn't leave you would get a fast busy from the switch

look at Options - should see either CFF or CFO - if CFO change to CFF

If CFF - Check NCOS on phone is able to dial ATTT Cell Phone

Also - can you post DCHannel Message with error.
