European & International Wholesale SIP Interconnect (Voice Termination)

European calling for smaller voice networks in recent times has become incredibly difficult due to the complexity of surcharging. Thanks to our wide range of international interconnects with major networks, we are able to offer high quality, aggressively competitive European and international calls for calls that originate from the UK and Europe while removing the stress and worry of surcharging (we don't normally surcharge!).

Furthermore, those who have been in the business for a while know the challenges in getting access to high quality, competitive priced international telephony. Our focus is purely on the quality CLI end of the market with a focus on reliable and consistent quality.

This is a premium product designed for residential and business communication providers including MVNOs who care about the quality of their international product offering while remaining competitive. Our standard landline and mobile rates for most European destinations are below 0.5p/min!

 

Network Access

Network Access (Interconnection) is normally via Public IP (SIP RFC 3261). All of our network can be reached via LINX (London Internet Exchange) and would prefer traffic to us routed via LINX if not on a direct interconnect where our network has a presence. Given Ofcom's recent resilience guidance around interconnection we will need to verify your network path to our network (especially if we provide 999 access).

Initial Channel/Balance Limits

On the second and subsequent topup this can be increase for free within reason to a limit in blocks of 32 concurrent calls of your choice.

Discount on Volumes

Over the years, Aloha has wasted many a man hours customising rates for potential customers where reality, the minutes promised have not materialised. Therefore Aloha has changed it's approach. 

Aloha offers a scheme that if a customer tops up £1000 GBP or more and spends this within a calendar month, then 5% extra credit is provided at each subsequent top up pending this original condition has been met. 

If a customers spend is substantially more than this, then custom destination rates maybe applied.

 

Prohibited Traffic

Aloha operates purely in the premium, quality end of the market and primarily do not want 1 or select handful of clients degrading our network for our other clients. We take complete pride in providing a high quality service/network . Secondly we have regulatory commitments to adhere to. If your traffic meets one of the following conditions below we will be unable to assist you: 

  • High Volume, Automated/Predictive Diallers 
  • Low ASR/ACD (i.e a minimum of 50%/50 seconds respectively is required) - including data cleansing and short call durations
  • AIT (Artificially Inflated Traffic)
  • Nuisance Calls
  • High risk of law enforcement information requests.
  • Sending calls with invalid/fake/fraudulent CLI.

Fraud Prevention

The sad fact is Telecom Fraud is on the increase and some estimate it to cost the industry > $30 Billion Dollars annually.

Unfortunately we see some form of fraudulent activity almost daily. Most being in the form of hacked systems (our client or our clients subscriber)

After special consideration and in the interest of our customers. There are certain numbers that we block on our network that we believe have been linked to fraud. We only block numbers that have proven to have links with fraud. Rarely area codes. This restriction can be lifted if requested. Typically this is more related to International calls than national as there are industry mechanisms to potentially reclaim money.

To help customers identify higher than normal spending patterns we also provide a warning system as standard.

If a customer spends 'x' in a 30 minute period, then an email is sent to both the client and the account manager. This simple feature has helped many a clients identify abnormal activity and minimise loss. We also offer the ability to limit your daily spend and block your interconnects if a high spend per minute is reached.
