Sip Registration Address

[viptelprueba]

My problem is this, i have read the manual that tellsme how to stack two quadros. In the manuall i read that the only way (in that scenario) to do this i must alter the defaults sip registration names of each extention, in order to use the both quadros as one, my question is how do i know if the numbers enter by me will register in epigy server, do i need something o authorization to do this.... Is there any other way to stack two quadros that doesnt involve alteration of sip registration numbers (default ones), thank you.... Edited by: viptelprueba
