Using Twilio with Testmate and Expressway

So at Yarnlab we do a lot of testing of phone systems all around the world but one of the challenges is getting real numbers in all the different counties. 

We started to use Twilio for this and found that we could use expressways for this and could rely on the secure network traversal. This could also work for small offices in countries where LBO is often deployed although i not sure if this would work financially for large offices due to RMLs.

Just thought i would share some of the setup info 

Most things works except for mid call CLI update for transfer (CUCM uses INVITE) so numbers don't update.

Next Steps

We are also soon going to release the Cloud PSTN remote that uses Twilio to allow testing with numbers on demand in any country that Twilio supports 

This will make testing global deployment much easier
