I need to use the function of "redirecting a call" or "a conference call" of the device LILNKSYS SP A942. When transferring the phone call via reception (SPA942) from one SIP account to another SIP account (before connecting the callers together) the connectivity is interrupted. SPA942 is not connected to the telephone switchboard and it recognises independent SIP accounts. What/where is the problem please? Thank you for your help.
