miniSIPServer on Debian 9

miniSIPServer on Debian 9

It is a good news to see that the latest Debian 9 is released. We have downloaded and tested it in our lab.

Debian 9 is very interesting. Since it is a stable version, it is important for us to run miniSIPServer on this system. We have to find that so many libraries and softwares have been changed or upgraded. Previous MSS versions cannot work on it by default.

We did lots of work to fix these conflict and upgrade MSS to V31 (build 20170621). And we are exciting to announce that the latest versions can still work on previous Debian systems, such as Debian 7 and Debian 8. Everything is perfect now!

If you want to try Debian 9, please upgrade MSS to the latest V31. And please refresh the document for more details about libraries.

Concurrent calls of SIP trunk

Concurrent calls of SIP trunk

By default, MSS previous versions don’t limit concurrent calls of SIP trunk. That means you can make or receive calls as much as you can. If peer sides don’t have enough resources, they will reject calls by themselves. But now in some scenarios, customers hope MSS can handle concurrent calls and limit them automatically.

To fit this requirement, we upgrade MSS to provide concurrent calls configurations in SIP trunk. Too much calls will be rejected by MSS itself. Please refer to following figure for more details about these items.

Please pay attention to these.

(1) These items are independent. You can configure different values for them to limit different concurrent calls for outgoing calls and incoming calls.

(2) If one of them is zero, in fact all them can be zero, that means only incoming calls can be received, or can only make outgoing calls outsides.

Modification of “one number” service

Modification of “one number” service

We upgraded miniSIPServer V30 today to change “one number, multi-devices” service in local user’s configuration. In previous versions, we don’t need configure anything to enable this feature in local user since it was enabled by default. Customers think it is good idea to reduce configuraiton workload, but it brings new management problem. In fact, they hope to be able to control which local users can have this feature. In most scenarios, only some local users have several phones with same number, others are not permit to do that.

To fit this requirement, we add a new optional item in local user’s configuration. Please refer to following figure for more details. By default, this service is not enabled now until you configure it obviously.

One number service right in local user's configuration.

This modification is applied to cloud MSS too.

Citel Technologies, Inc. Announces Interoperability with MyVOIPApp miniSIPServer

Citel Technologies, Inc. Announces Interoperability with MyVOIPApp miniSIPServer

AMHERST, NY and ShenZhen, P.R. China — August 4, 2016 — Citel Technologies, Inc., is pleased to announce that it has successfully completed interoperability testing with MyVoIPApp’s miniSIPServer, a software-based SIP PBX, designed for small and middle size companies, miniSIPServer is very easy to use with rich features and can work on multi-platforms, such as Windows and Linux whilst also fitting both IPv4 and IPv6 networks.

The Portico™ TVA™ offers companies the means to migrate their customers to VoIP without the unnecessary burden of ripping and replacing existing cabling infrastructure, purchasing new IP phones and installing Power over Ethernet switches. Customers can retain their existing digital, analog and Centrex phones without removing the existing switches by SIP enabling those phones through the use of the Portico™ TVA™.  This is a quick and cost-effective means of VoIP migration.

“Used together, the two innovative solutions provide companies with the fastest and most cost-efficient means to upgrade from legacy systems to modern Unified Communications,” said Ian Gomm, VP of Sales & Marketing for Citel.

Citel and MyVoIPApp kicked off interop testing with miniSIPServer at the request of a high-profile customer who was looking to use this Windows-platformed softswitch for a cross-country network of customer service training centres. “We have undertaken interoperability with many IP PBXs over the years, and know that sometimes some systems are easier than others to complete. MiniSIPServer was new to us, but I was really pleased to hear engineers’ initial feedback that the system was easy to work with and interop had gone smoothly” said Andrew Davies, VP, Engineering at Citel. He continued “Then they showed me some quite sophisticated presence monitoring and Busy Lamp Field functionality and I saw the product was a great fit with the Portico™ TVA™, wherever digital business phones were the preferred handset. We look forward to taking the relationship further.”

Refined SMTP library

Refined SMTP library

In voice mail feature, MSS need use SMTP library to send emails. Since MSS can embed Python script functions, it is easy to use Python-smtplib to send email. That’s what we done and it works well, we are satisfied with it.

But smtplib is too old ( in python 2.7) to fit some modem SMTP servers’ requirements. It also has a shortage. It is synchronous. That means it can block thread when sending a email, then its performance is poor and cannot fit our requirements in cloud system.

Something is changed, we want MSS to be better, so we develop a new SMTP library to send voice mails. This SMTP library is asynchronous and can work perfectly with most SMTP servers. And, it is written in C/C++ language.

We upgraded MSS V23 and cloud-MSS to replace python-smtplib with this new SMTP library.

Hope you can enjoy latest versions.

By the way, since MSS V23 has been released for several months and we got very better result, we think it is time to release new LTS version which is V24  and new stable version which is V25 in the end of this year or in the beginning of next year.

As you know, it is better to stay with previous Ubuntu LTS versions, such as 12.04 and 14.04.

shared-appearance feature

shared-appearance feature

MSS V23 was released yesterday. The main feature of this version is “shared appearance”. In one number service, the SIP phones can subscribe others’s dialog status, and MSS will notify them with all kinds of busy signals: early, confirmed, terminated, and so on.

Please note that this feature requires SIP phones to have SUBSCRIBE/NOTIFY capabilities. If your phones cannot support these methods, this feature will be discard automatically.

You need configure nothing to enable this feature. So easy, right? Hope you can enjoy it!

miniSIPServer V21 released!

miniSIPServer V21 released!

V21 is released today to support a new service: one number, multi-devices.

This service can enable MSS to accept several SIP phones with same local user’s number and authorization. And for incoming calls, all these phones will be ringing at the same time.

“One number” service looks like “ring group” feature. The difference is that “one number” service permits several SIP phones to share same local user profile, but “ring group” service requires SIP phones configured with different user profiles.

Please refer to following document for more details about this feature:

http://www.myvoipapp.com/docs/mss_services/one-number/index.html

By the way, Cloud-MSS has been upgraded to support this feature too.

Hope you can enjoy it!

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:

Happy new year! 64 bits miniSIPServer!

Happy new year! 64 bits miniSIPServer!

Today we upgrade miniSIPServer V14 to support 64 bits Debian and Ubuntu. That’s a great news for some of our customers.

As we know, in some networks, customers have deployed 64 bits Debian or Ubuntu servers. So when we want to install previous 32 bits miniSIPServer in their servers, it is required to install some additional 32 bits libraries. Of course, it is no problem to do that, but some customers often think it could be unstable for their servers.

So we decide to migrate MSS to 64 bits to fit this requirement. Now it is unnecessary to care about 32 bits problem.

For customers who are using 64 bits Windows, it is unnecessary to care about 32 bits problem. Windows can process them in perfect way, so please keep current versions.
