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.
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.
