Residual Translations: Problems & Solutions

Posted by John Livingston on April 15, 2015 at 11:00 AM

While the advent of number portability has opened up a whole new world of possibilities for consumers, it has also opened up several problems that can occur. John Livingston, a VoIP Innovations Technical Representative, knows all too well that one of those problems is residual translations. In today's post, he’ll be covering its definition, issues, and solutions.

Residual translations is an issue unique to the porting process as it is caused by information being left in a losing provider’s system upon completion of a number port. When a number port completes, it is the gaining provider’s responsibility to verify that all of the routing information for a given number is correctly added to their equipment. It is the losing provider’s responsibility to have their routing information removed from their servers. Where this tends to get complicated is when both parties have routing information built in their respective switches. This will cause calls to start misrouting over the former provider. Residual_Translations

The best way to fix this would be to reach out to the former provider and have them verify the number ported. Once they verify this they could then remove the old translations which would allow calls to route to the new provider. While most providers will remove this on their own, some providers will leave translations in for 24 hours in case the number should need to be moved back. Generally this process is rather easy and can be completed pretty quickly.

As a VoIP Innovations customer, if you should encounter this after a number port your best course of action would be to reach out to the previous provider to have this corrected.  If you encounter any problems with this, we advise contacting our Porting Team if this is within the 24-48 hour period after the port completion. This way, they can reach out to the provider and ask they verify translations were fully removed. If it is beyond this timeframe either support or porting would be able to handle this for you as well.
