I use 2talk a lot for my work, and I have noticed there is quite substantial answer lag. I have tested this by calling my own landline and have confirmed that this is an issue. There might be a delay of up to even 2 seconds, between which the other party answers the phone, and when my side starts ringing and their voice comes through. This can be quite embarassing, as it means I often miss their introduction and sometimes will ask for the person who I am speaking to.
It doesn't happen all the time, I might say about ~20% of the time, but it seems somewhat random. Has anyone else experienced this or can offer any solutions?
