I`m new to this forum and I apologies if this question has been already asked and answered.
We currently have 2 asterisk servers. One is in US, Chicago (version 1.4.0) and the second one is in Romania, Arad (version 1.4.2). We have a very large customer support project so the servers are really helping us a lot. The servers connect one to another so calls from RO to US can be made through asterisks servers and the same from US to RO. My question is, if i upgrade the server from Chicago which is version 1.4.0 to 1.6.1 will it still be able to connect to the server from Arad which is 1.4.2 ? If one is 1.6.1 and the other 1.4.2, will I have problems in interconnecting them ? I`m planing to upgrade the server from Arad too but not right now, maybe in a month or two.
Thanks in advanced for all your answers
