We have recently swapped from a Zultys to an Asterisk system and have taken teh same trunking provider with us, Gamma. However, we seem to now be having problems with the call quality and I wanted to try another supplier and wondered who the best one to use in the UK would be, any suggestions much appreciated.
i was just about to suggest someone, but then realised that they peer from Gamma. had no problem with call quality though.
