hi all i have 2x UCM62xx set up one using SIP, the other using PSTN trunks.
the PSTN system is currently being trialed as our main system but since installing the system my boss has found that he often talks over clients when he receives a call. internal between extensions is fine no audio overlap/ latency. when we do get an external call you have to awkwardly have to wait 2sec before customer is finished saying what they need to say to avoid talking over their audio.
i can prove this by the fact the boss and i have tested the SIP and PSTN system simultaneously . the SIP system there is still latency but not so much as the PSTN trunks.
any ideas would be grateful as to how to shrink the latency til it is non existent
