Quick query regarding FXO gateways (UK PSTN lines). Aside from Patton and Welltech, what other choice do we have for gateways that wouldn't be too complicated to configure for 3CX? The supported gateways don't seem to give much choice, and availability in the UK is very difficult for both these brands especially with their FXO models. Currently using a Patton SN4112 at a client's site and I'm fairly happy with the voice quality but can't help think it could be better. Adjusted gain settings etc according to advice online from Patton which led to a huge improvement, but still want to try something else at a different site (as struggling to purchase another Patton in the UK without importing), pending recommendations from anyone here. Any input would be appreciated, thanks.
