Multiple Extensions


#1

I have enabled an extension to have 2 concurrent registrations, but only one of them is working at any given time.

They are both “External” extensions. I have the same setup on two phones that are “Internal” and they work fine. Could there be something different because they are off site?


#2

Are the remote phones at the same location and behind the same firewall. If so, then possibly.

Hi Wayne,

I can be wrrrrong ive been wrrrrong before but…

Please make sure that your telephone has Ext 1 as using SIP UDP 5060 and Ext 2 to use SIP UDP 5061 else you will have registration and incoming call issues.

You will also need to ensure that the firewalls at both ends translate those 2 x ports correctly to the telephone system performing the registration.

Be mindful also the RTP ports…
