I have a very basic VOIP system that has one phone number with 2 simulatneous access lines.
I started using SIP credentials instead of an analog adapter and purchased three Cisco SPA 303 phones. One for my office, one for my workroom, and one for my front desk. I got the three phones working fine. Each can place and receive calls fine. The secondary "clone" line is working well too — I am able to place two simultaneous calls without issue. My problem now is that the phones do not “see” each other. If I answer the phone in my office then put the call on hold, I cannot seem to be able to pickup that call on either of the other phones… Any suggestions for how to properly configure this?
