I always have an active call through one SIP account as it is connected to Vicidial auto dialer. When I go to make a call with another SIP account the Vicidial call disconnects. I previously used Jitsi softphone which would just put the Vicidial call on hold.
How do I prevent it disconnecting?
It is weird behaviour because it also doesn't call the second line after it disconnects. I have to call a second time for it to actually call.
