Just wondering if I want to use a UK based VoIP service while travelling abroad (in Turkey), what sort of delay should I expect in the call? I'm talking about making a VoIP call from abroad to a PSTN number in that country. That means the call will have to travel to the VoIP company server in the UK, and then send it back as a regular call. Should I expect that to significantly impact the quality of the call?
Thanks in advance!
