    1. I am getting periodic beeping (not call waiting) during calls and at different intervals (so its not a timer as with another post to these forums).

    I tried multiple VOIP ITSP's as well with the same results. They are Junction Networks, Teliax and voipbusters.

    I was running asterisk on this box prior to reformmating and installing win server 2k3R2 without the beeps.

    I do have a consistent error in the system log that I have attached here but I do not know how that would cause the problem.

    2. Having to go to the voip section and re-register every so often as the registration seems to time out. Any hints here? The line log shows the lines are fine and the phone thinks its fine. Dial tone is there but any call gives me fast busy.

    13:37:05.765 Endpoint::findSource Unrecognizable source. More than one line corresponds received INVITE
    13:36:05.593 Endpoint::findSource Unrecognizable source. More than one line corresponds received INVITE

    this pretty much happens every minute.
    Thanks in advance,
    k

    With the new build the recurring message becomes the following:

    16:42:37.781 Endpoint::findSource Ambiguous configuration.3 source lines correspond to incoming call.INVITE Parameters: Contact IP: '207.174.202.4'; From: 'Unknown'; To: 'ksantella'; Rline: 'ksantella'; Contact: 'Unknown'. Line:CfgExtLine:9110 used as fallback!

    I have 4 voip providers setup. 1 has in/out with a did and three are out only. I get this message every minute.

    I think your call routing is out of order.

    Looks like your call is configured to route from one to many, they all want to answer the invite at the same time.

    As you mentioned you got one line as in/out and have the others as out so they should not react on the invite comming in.

    Lets test this.

    Configure the lines like:

    Line 1, answer after 0
    Line 2, answer after 10
    Line 3, answer after 20
    Line 4, answer after 30

    If that works move the time delays closer eg instead 10 make it 5 etc.

    See what happens.

    thanks but it didnt do the trick. There are 4 outgoing lines that have different dialing rules i.e. using one supplier would require dialing 1 then the number (then stripping the 1 with the r) same for 2,3 and 4. The ring setting would just change the incoming call which only exists and is checked on the first voip provider.

    Hi there

    This issue may sometimes be visible when you have multiple providers using the same Authentication ID - which means that the system will be unable to use the Authentication ID to distinguish the source of an incoming call.

    You may try:

    1. For, say, provider "A", obtain a list of possible IP addresses which can initiate a call. The provider may be able to provide you this list. Alternatively the log messages can be used to identify the IP sourcing the call. In your case, source is "207.174.202.4". Appears to be a RockyNet VoIP service.
    2. In this provider's Advanced Configuration, enable the "Use IP in 'Contact' to recognize source" checkbox.
    3. Put the list of IPs for this provider in the "IP Range" text box. The

    Hope this helps...

    Thanks. I have contacted my voip providers for this info and will let you know how I make out. Have you any ideas about the beeping? The errors in the server log are not stopping the 3CX from working but the beeping will stop me from using. As i stated, I know that when this machine was a linux box it ran a pbx (asterisk) without the beeps. My setup is

    Verizon FIOS static ip - trendnet gigabit switch - linksys wireless router - windows server 2003 R2 running 3CX and Linksys 942 below router.

    all required ports open on router and voice travels in and out. I even have used the 3cx softphone externally with successful communications.

    Any ideas anyone? I am stumped.

    It has no cadence. it happens every so often. It is heard on both ends of the call. If you want to see for yourself I can give you the number.

    Does 3cx softphone had those beepings?

    I am on a limb here, but is your voip provider using SRTP?

    I think the DTMF detection method detects certain tones or signals on the line, and extends them to the perceived length and tries to make sense out of it but not converting it into a Dial Tone.

    I do not have the problem (yet) so it is hard to figure it out, but I heard scenarios that beeps occur with the new SRTP. Ask you VSP if they use cisco kit :).

    Henk,

    I tried on the softphone and no I do not hear the beepings although the communication is only one way so far from linksys 942 to 3cx softphone. I have all required ports opened and the calls are setup ok (see below);

    11:00:23.846 CallLegImpl::eek:nConnected Call(C:2B): Created audio channel for Ext.301 (192.168.1.6:16448) with third party (68.243.220.60:5062)
    11:00:23.831 StratInOut::eek:nConnected Call(C:2B): Setup completed for call from Ext.302 to Ext.301
    11:00:23.831 CallLegImpl::eek:nConnected Call(C:2B): Created audio channel for Ext.302 (68.243.220.60:5062) with third party (192.168.1.6:16448)

    301 is linksys 942 and 302 is an external extension 3cx softphone.

    ITFARMER

    As far as the voip supplier I do not know but will enquire. I have tried using multiple with the same results (voipbuster, teliax and junction networks) It happens inbound and outbound. Unless they all have this cisco kit as you mention then I am assuming this is not the issue. I thought it may be the phone dtmf as I cant leave messages when someone I call goes into their voicemails. It just says goodbye as it does not hear my voice after the beep. The phone has a DTMF selection for AVT and Tx method. Mine are setup as process AVT YES and TX method InBand (other options AVT,INFO,AUTO,INBAND+INFO,AVT+INFO)

    any ideas?

    Ok. I've done some more digging. I talked with one of my voip suppliers and they do not send inband dtmf. I am seeing inband dtmf in the server log which is corresponding to the beeps. Where is this coming from? The beeps as I've stated have no cadence. Here is the log posting:

    15:24:13.862 StratLink::eek:nHangUp Call(C:54): Ext.301 hung up call; reason: BYE
    15:23:58.050 MediaServerReporting::DTMFhandler from 'dylanpbx:0/MediaServer':DTMF (in-band) from 207.174.202.4:14872 detected.
    15:22:34.784 MediaServerReporting::DTMFhandler from 'dylanpbx:0/MediaServer':DTMF (in-band) from 207.174.202.4:14872 detected.
    15:22:17.753 MediaServerReporting::DTMFhandler from 'dylanpbx:0/MediaServer':DTMF (RTP) from 192.168.1.6:16428 arrived. in-band DTMF tone detection is turned off.
    15:22:15.050 CallLegImpl::eek:nConnected Call(C:54): Created audio channel for Ln:9220@Teliax (207.174.202.4:14872) with Media Server (XX.XXX.XXX.XX:9142)
    15:22:15.050 StratInOut::eek:nConnected Call(C:54): Setup completed for call from Ext.301 to Ln:9220@Teliax
    15:22:15.050 CallLegImpl::eek:nConnected Call(C:54): Created audio channel for Ext.301 (192.168.1.6:16428) with Media Server (192.168.1.2:7160)

    There are two dtmf inband in the log and the voip itsp says they do not sent dtmf inband. I tried another voip itsp and have the same issue.

    Beeping annoyance

    I too have had this problem with both of my ITSP providers, Broadvoice and Voicestep. If you setup a phone to go directly to the provider it work like a charm and you hear no random beeps. I have only heard it when going through the PBX. I saw someone solved it by disabling DTMF autodetection on the Linksys phone. Either I did not set it up the way they did or this did not work for me. The othere suggestion I found but it also did not work was to uncheck bind to media server which should take the pbx out of the picture. I have a suspition the tones are a bug in the pbx with it not handling DTMF tone detection properly. Any help on this would make a few of us very happy.

    I am also having the same problem. I checked with my provider who advised that is was a problem with the PBX but could not give me any more info as to what potentially would be the cause. Look forward to a resolution to the problem.

    We believe this might be an issue in the current build.

    We have made some changes in the next build that will alleviate this. Note that you did not mention which VOIP provider it is, so it could very well be that its an unsupported VOIP provider. That said we have made improvements in this area which might fix the issue.

    Hi,

    Some info related to Linksys SPA9## and build 1928.

    Problem can be partially solved by setting "DTMF Process AVT" to "no" in phone configuration. (advanced configuration - "Ext n" page)

    Hopefully, 941 also has this setting.

    i have this same problem. my mentor at my previous company (sonusnetworks.com) has shed some light on this subject. the beeps may be caused by RTP arriving or delivered out sequence and dropped. many providers are able to resolve this by adjusting there jitter filter/buffer this is only if you have there end device. this may be something that should be implemented in the PBX.
