Other Features or Restrictions
Telenor filters all SMS arriving to their SMSC via international routes. This does not affect Vonage as our traffic arrives via direct connection to the Telenor SMSC.
You may also notice that our SMS numbers for Denmark are not the standard long virtual number format. They are in fact short codes, although the name would suggest otherwise. This means they are longer than the standard numbers associated with Denmark. This does not affect delivery and will not have any knock on effects for the end user.
Network level delivery receipts are supported to all networks.
