    Hi,

    We have 4 cordless phones. Everytime we receive a call atleast one of the phones does not ring.

    We currently have the four cordless phones setup to one W56P base with PBX delivering audio on each. Could this be a setting within the phone extension or ring group.

    Here is the log information:

    04/14/2018 10:04:30 AM - : Call to <sip:107@VOIPURL:5060> has failed; Cause: 487 Request Cancelled/INVITE from IP:5070

    04/14/2018 10:04:30 AM - : Call to <sip:106@VOIPURL:5060> has failed; Cause: 487 Request Cancelled/INVITE from IP:5070

    04/14/2018 10:04:30 AM -: Call to <sip:105@VOIPURL:5060> has failed; Cause: 487 Request Cancelled/INVITE from IP:5070

    04/14/2018 10:04:30 AM - : Call to <sip:104@VOIPURL:5060> has failed; Cause: 487 Request Cancelled/INVITE from IP:5070

    It goes on and on. This is just a small sample size showing that is it happening to each cordless and not just one.

    That message could simply indicate (if the IP:5070 is the PBX IP) that the call was answered (or went to voicemail or other destination) and it was telling the extensions to stop ringing.

    To have all four phones ring at the same time you have to make sure you have enough Simultaneous Calling capacity in your 3CX license. Since one phone is calling and four are ringing, if your 3CX is 4SC then that would be five calls.

    We have 8 available at one time and the caller is not internal, and the IP is an external IP.

    How many simultaneous calls will the base station support? I had a similar issue with a Gigaset base. Even though the base would support more than four handsets, four extensions being registered, only 3 would ring at a time(with all being in the same ring group), as the base could only support 3 simultaneous calls.

    The specs do say 4 simultaneous calls for that particular model base. Was each extension, assigned a unique local port? I only see port 5060 in the log.

    Not possible they all 4 share a Base which is assigned the port, not the handsets.

    Different from both the Panasonic, and Gigaset VoIP DECT base stations then, as they both allow (require) each extension registered, to have a different local port, in the same way you would assign a different port to a second extension key on a VoIP desk set. I'm really not certain how the Yealink functions without this option.
    Be that as it may....
    I'm wondering if, while supporting 4 simultaneous calls per base, it has a issue if four INVITES arrive about the same time, which would not be a usual senario.
