Emergency maintenance

Emergency maintenance

Our data center has detected an issue affecting the physical host on which our cloud system resides.

During this emergency maintenance:

  • Your virtual server may not be accessible.
  • No action is required from your end at this time.
  • We don’t have an ETA on when your virtual server will be brought back to its original state.

Once data center administrators have completed the investigation, we will update this blog with how we plan to proceed from here.

Your patience and understanding is greatly appreciated.

[Tue Apr 9 05:05:15 UTC 2019] updated: Everything is OK now and the service was broken for one hour this time. We will keep watching. If your SIP phones are out of services, please reboot them to take a try. If you still have problem, please update us. Thanks.

Media gateway and V30

Media gateway and V30

V30 is released. The key feature of this version is “media gateway”.

In fact, previous version has media gateway functions too, but these functions were combined in the same core with call-control and service-control tasks. For small size or middle size business, it is no problem to do that. But for huge size business, for example, our cloud-mss system, it could effect performance if media gateway is combined with other tasks.

We decided to separate media gateway module into an independent application. In cloud system, media gateway can be run in separated device. Several call servers can share the same media gateway server.

Since local MSS and cloud MSS have the same core, we merge this function back to V30. The difference is that the media gateway is an independent inner task in local MSS application.

This feature doesn’t require any modification in configuration or GUI. By default, you should not notice this change. We believe new core can be more stabler and more flexible.  Hope you can enjoy it!

Some virtual servers changed

Some virtual servers changed

Some virtual servers in cloud-MSS system have been changed, please pay attention to these items.

STUN server

Each virtual SIP server will enable STUN feature. For example, if the SIP server address is “”, its STUN server can also be the same address. That means “” is also its STUN server address.

Now we suggest “” by default. It is a simple public STUN server for all virtual SIP servers. Of course, you can still configure your virtual SIP server address as your STUN server.

SMTP server

In voice-mail feature, we need a SMTP server to send emails with attached audio files. Each virtual SIP server can be configured with customers’ own SMTP servers. But we find it could make several problems. For example, most customers try to use Gmail SMTP server. Gmail SMTP server requires that you need enable POP/SMTP firstly, and grand other access. Most customers don’t know how to do that.

So we disable SMTP server configurations. All voice mails will be sent from our own SMTP server.  Most important is that you will need check your spam box if you cannot find voice email in ‘inbox’.

Reseller for Cloud-MSS

Reseller for Cloud-MSS

Since cloud-mss is online, there are lots of customers ask us about reseller funciton. Thanks for their suggestions. We do some research on this topic and find it could be classified to two types:

(1) Some customers are professional communication providers for enterprises. They often install several cloud-mss servers for their own customers, so it is very useful if they can manage several nodes in one account.

(2) Some cutstomers provide SIP-PBX services for their local subscribers with their own domain names, so they not only want to manage several virtual sip-pbx nodes in one account, but also want to get more discount pricing.

We add ‘reseller’ function into cloud-mss system. It is free to register cloud-mss account and users can create and manage several cloud-mss nodes. Each node can be configured independantly just like common node.

If you are interesting in this topic, please take a try and feel free to contact us if you have any question or suggestion.

Please refer to our online document for more details:

Notice: cloud-mss is migrating

Notice: cloud-mss is migrating

We are migrating cloud-mss servers to a new data centre which can provide more bandwidth and be more stable.

The process will take one or two hours. We have to disconnect all our servers and we are very sorry to stop all customers’ services and thanks for your patient.

We will update this blog if all jobs are finished. Thank you very much.

Offline instant messages

Offline instant messages

Today we upgrade cloud-MSS to new version to support offline-IM feature.

In a unified communication environment, it is very common for users to send or receive offline instant messages, specially some customers use cloud-MSS as their internal communication tool.

With this new version, cloud-MSS can support IM as following:

(1) If called party is online, Cloud-MSS will send IM to it immediately.

(2) If called party is offline, Cloud-MSS will save its offline IM. Clou-MSS can store no more than total 10 offline-IM for each local user. Each IM should be less than 200 characters.

(3) If called party is back to online again, Cloud-MSS will send its offline-IM to it automatically.

You don’t need configure anything for this feature, it is so easy to setup a UC system for your business now. Why not take a try? 🙂

Hunt-group in Cloud IPPBX

Hunt-group in Cloud IPPBX

Yesterday we upgraded Cloud-miniSipServer to support hunt-group feature.

HG feature has been supported in local minisipserver for a long time. Lots of small companies use this feature to service their customers. The HG service in cloud-minisipserver is almost same with local-minisipserver, such as same service log, same configurations.

The difference is GUI display. Please refer to following figures.

One is for cloud-minisipserver.
