Brekeke SIP Server can run on WindowsXP, Windows7 and Windows10. But theses OS are designed for personal computers not for server uses. Also Microsoft ended the support for WindowsXP 9 years ago. Do you have any reason to use such an old OS for SIP redundancy? If you use Linux, you can manage ...

Are you using Windows XP for running Brekeke SIP Servers under redundancy deployments?

I recommend you use Linux..

There are several ways. You may find an example in the Tutorial. http://www.brekeke.com/doc/sip/sip_tutorial_dialplan.pdf DialPlan accepts Regular Expression so OR operator is |. https://en.wikipedia.org/wiki/Regular_expression If DID are 11111, 22222 and 33333, you can define them at ...

It seems that the permission of the database file was modified.

Please make sure that the file system doesn't have bad-sectors.

Are you using 3rd party database system for T_REGISTERED?

Reboot the Windows if you didn't try it yet.

Is it an evaluation license of Brekeke PBX ?

Use From/displayname in Deploy Pattern For example.. Matching Pattern $request = ^INVITE $getDisplayName(From)=(.{2})(\d+)(_\d+)( |( -))([a-zA-Z ]+)|([+.-]) Deploy Pattern From/displayname = %1%2%3%4%5%6 or I simplified your regex pattern. Matching Pattern $request = ^INVITE $getDisplayName(From ...

The log indicates "TCP:connect timed out "

Make sure the firewall doesn't block TCP 5060 port.

Can you find the call record in the [Logs]->[Session Logs] page?

Is the customer's SIP client (10.3.3.3) located in the same LAN without NAT?

Please refer this. http://wiki.brekeke.com/wiki/PushNotification With this feature, you can send push notification message to iOS and Android. Also a message can start your SIP client app automatically. But you need to add an option to the product license for enabling this feature in Brekeke SIP ...

Yeah, it is right. I already asked it to the developer.

Since it is disabled, it is greyed-out.
If you move the mouse cursor to the disabled rule, the background color will be yellow.

If you failed login multiple times (eg. invalid password), the SIP Server's GUI blocks your IP address for a while.

It is depending on the callee, IVR. Generally a callee will show the caller's display name instead of From-URI. Try this. Matching Patterns $request = ^INVITE To = sip:654321@ $getUri(From) = (.+) Deploy Patterns From = "123456" <%1> If you are using the latest version (I strongly recommend), you ...

Which standard, SIP product or provider require such a Call-ID?
Call-ID is an identifier so it doesn't have any meanings it self.

Therefore DialPlan doesn't allow you to specify the value of Call-ID.
If you want to specify it, you need to create a plugin.

It can be done if you write own plugin code...

Yes.

The packet was corrupted before it reached the SIP Server.
Other SIP packets less than 1500 bytes are OK.

Expand OS's MTU but I recommend you use TCP instead of UDP because other network entities such as router will also limit the size.

The reason of the issue is the packet size. The "183 Session Progress" packet sent from 204.15.169.92 was fragmented and these fragmented frames were delayed . The fragmentation happened because the packet size exceeded 1500 bytes. The wireshark indicates that the packet size is 1520 bytes. As you ...

Vaclav,
Is it the pcap you have SDP issue??

I can see "c=" line in the outgoing SDP which points 185.164.x.x what you defined.

Vaclav
I've downloaded it. So you can remove it now.

Does the issue still happen even if you don't use RTP-relay?

Does the same issue happen even if you make a call from another SIP client or VoIP service?

It seems "Session Name (s): iMax_SS " is also missing.

vaclav_prokes,
It is Wireshark's expression of SDP not original raw data..

Can you paste the original SDP content here?
