We have an issue with our system when leaving voicemail message on people mobile phone voicemail messages. The issue only seems to occur when calling a UK Vodafone number.
Calls Only to UK Vodafone
We get a clear line with no issues, hear the vodafone announcement, then the tone. Immediately after the tone we hear a garbled noise ‘Alien’ or ‘Darlek’ kind of thing.
Has anyone seen the same and resolved it?
