Configuring Circuit to Support 14-digit ANI for Blackberry MVS

[Tom Dillon]

Hi, we are trying to request the correct feature package for an existing ISDN/PRI circuit that will support a 14-digit ANI.  Our Telco provider is telling us that they only support 10 digits and the ANI must be a valid DN within our DID range on the circuit.

Blackberry’s mobile voice system (MVS) requires the outbound call to pass the 10-digit calling number plus additional 4 digits to the blackberry phone.

Does anyone know the name for feature package that will support a 14-digit ANI on the carrier’s equipment?  Our provider is at&t.

Thanks,

Tom.

If you find this out, please post back. ATT cant seem to figure it out either.

ATT knows exactly how to do this, they just won't remove outbound ANI filtering from their PRIs. Other providers (typically CLECs) have no problem providing this service though. I always ask the provider during contract negotiation if they filter ANI on outbound calls and make sure they write their answer into the contract.

ANI is valid to at least fifteen digits as that is the E.164 standard. Your best bet is to find a carrier that won't filter your PRI.  Another option may be to see if the Blackberry MVS server product can work with RDNIS information instead. Some carriers are more lienient with the RDNIS values. ATT for example allows the SIP-equivelent to RDNIS (Redirected or Diverted headers) to be any value on some products/contracts.

Thanks Jon for the information!  This finally gives us something to help communicate our request to at&t and probably other providers.  Also, RIM mentioned that they have a patch for a customer in Europe that removes the requirement for 14 digits.  Apparently they have had problems with customer Blackberry phones roaming between countries.  We have not heard if RIM will provide us the patch.  It sure would make it much easier to implement their single number reach service if they can do it with a 10-digit ANI.

We really appreciate your time and information,

Tom.

Thanks again Jon.  We finally got the outbound calls with a 14-digit ANI.  It turned out to be exactly what you said   AT&T was filtering the ANI.  They removed the filtering and it works perfectly.
