    Hi

    I have a problem with this version and my grandstream phones.
    When I use ring groups and call from an external number, all the phones ring, but if I pick up a phone there is a delay of several seconds until the connection is established. The other phones continue to ring.
    There was no problem in BETA 5

    Any suggestions ?

    Could be several things:

    - server (capacity etc how quick it respond)
    - network (the pieces of string) thing in the line of QoS
    - phone (Frame size, DTMF relay etc)
    - gateway
    - 3cx...... NAAa that would nt be the case :wink:

    So it could be one or all or a combination of the above. I suggest slowly eliminate things. It is all about getting the software and the phones to realise that they can stop ringing and that the call is connected.

    Hi,

    We cannot reproduce the delay issue you described.


    If you are using a GXP2000 and experiencing this issue please enable the "Turn off speaker on remote disconnect:" under the account settings.

    Also please upgrade to latest stable firmware version.

    I have made a lot of tests now:

    1 ) Server capacity should be no problem, it runs on a P4 2,8 GHz D with 1M of RAM, W2003 Server with no other tasks to do. There is no CPU load at all.
    2) Network, I run a clean 1G network with no latency.

    3) I have a 4M connection to the Internet with no load and a low latency.

    4) I have tried enabling "Turn off speaker on remote disconnect", but no difference.

    I have 4 GXP2000, 1 HT486 and 1 GXV3000.
    All run on the latest stable firmware.

    If I only have one phone in the ring group, there is no problem, but as soon as I add number 2 phone in the ring group, the problem arrive.

    I will try more, please advice

    An update:

    My ring strategy is "Ring all"

    If there is only 2 phones on the list, the problem is minimal.
    If I pick up the 1. phone on the list, I see no problem.
    If I pick up the last phone (number 5), the problem is maximal.

    CPC call progress control i think.

    Not sure yet how to solve that but will do a bit of looking arround and reading up on your kit . (no promisses)

    I have used the default settings on my Grandstream phones, but still no better result.
    It's working with the Beta 3 software.

    I use default settings on the 3cx:
    Internal calls port : 7000-7500
    External calls port : 9000-9003

    One my Grandstream's I use :
    Local RTP port : 5004

    Is this okay ?

    Hi,

    Your port numbers are fine.

    If you are picking up the phone and the rest of the phones continue to ring this seems to be a problem with Call initializaion and tear down, this would most likely be a SIP issue not RTP.
    Also this is just the GXP2000s which are doing this right ?

    can you please post the firmware version of the GXP2000? You can do this by logging into the phone and checking the "Software Version: " under the Stauts page of the grandstream phone.

    Thanks very much for the answer.
    It is a problem with both my HT-486, GXP2000's and my GXV3000.
    On my HT-484 I run 1.0.8.33.
    On my GXP-2000 I run 1.1.1.14.
    On my GXV-3000 I run 1.0.0.33

    I have tried to upgrade my GXP-2000 to 1.1.3.2 and tried to upgrade my GXV-3000 to 1.1.3.2, but it makes no difference.

    I think it could be my SIP settings in the config-files for the phones, do you have a suggestion about some settings to play around with ?

    I have changed the following setting:

    Enable Call Features. 0 - no, 1 - yes

    I changed from 1 to 0, it helped a lot, now the delay from I pick up the phone until I can hear the vioce is around 8 seconds.
    It is acceptable now, but maybe it could be improved in the future

    I have upgraded to v3.0.1699.0 and have done some logging, and the problem does go away if there is only one phone in the ring group.

    With one phone in the group:
    14:41:50.582 StratLink::eek:nHangUp Call(C:1): got Hang-Up from Ext.211; reason: BYE
    14:41:44.519 CallLegImpl::eek:nConnected Established media channel for Ext.211: remote=192.168.101.152:5004; local=192.168.101.203:7000
    14:41:44.504 StratInOut::eek:nConnected Call from Ln:10000@Telsome 1 to Ext.211 is established
    14:41:44.504 CallLegImpl::eek:nConnected Established media channel for Ln:10000@Telsome 1: remote=193.223.99.25:30124; local=83.93.49.68:9000
    14:41:38.176 CallConf::eek:nIncoming Incoming call from Ln:10000@Telsome 1 to sip:73540054@83.93.49.68

    With 5 phones in the group:
    14:44:25.766 StratLink::eek:nHangUp Call(C:2): got Hang-Up from Ext.211; reason: BYE
    14:44:20.594 CallLegImpl::eek:nConnected Established media channel for Ext.211: remote=192.168.101.152:5004; local=192.168.101.203:7004

    Hey, that is an interesting log.

    Question for 3cX:

    What is the message sequence (internal) for 3cx? Does it check the registration and diverstion status of each phone before sending the ring request? That would explain why 5 phone take longer.

    Question for kelddamsbo:

    The phones that are member of your ring group are they all configure the same way? I am trying to establish the weakest link, not sure how it all works but it could be that only a ring request is send after the "slowest" phone is found.

    All the phones are Grandstream
    4 GXP-2000
    1 GXV-3000

    All are configured the same way from a template.
    It does not matter in whitch order the telephones are in the ring group, the problem is there even if there is only 2 GXP-2000 in the group. If only one telephone are in the group, there is no problem.
