Recommend some effective carrier grade VoIP softswitches

I am looking for carrier grade softswitch that integrates well with splynx.

I am currently reviewing the sipwise product portfolio to meet my business model where I intend to use
a. C5 and C4 softswithces for SIP,XMPP,WEBRTC relays and TDM/PSTN via SS7 respectively with providers.
b. CPBX as cloud hosted IPPBX for enterprise customers
c. SIp:phone for both enterprise and residential clients as option for those who do not require a hardware IP phone.

Any other alternatives folks in our community are using that they would like to recommend?


We are interested also. let me know if you find a solution.

We provide DID service in an old stand alone softsowitch called IPsmartX. getting new softswitch that can integrate with Splynx wil be great.


Currently we have added PortaOne support, but personally I’m not a big fan of their products. We have added it for one project, but it’s available for public too. I would like to start checking voice softswitches during this month

Hi alex dd you now the price of the porta one switch ?

Hi Alvin, it’s very expensive, I think they charge over 100K $ one time + a lot for support.
I found these platform that we would like to test in near feature :
Asterisk in general -, as I know there is a Radius addon to it. But I will try also to grab CDR directly from it, as a2bill was doing.
Free PBX -
Elastix -
Kamailio SIP server -
Bicom Systems -

So, if anyone has feedback regarding these platforms, please feel free to share it with us

Many thanks Alex for the feedback.
I am currently digesting the Sipwise Community Edition (Sipwise CE) documentation -
Generally it has a very well thought out architecture - with very rich API.
The difference between the Sipwise CE and the Pro and Carrier edition is technical support especially with high availability and load balancing deployment scenarios. Nevertherless that is also well documented for anybody willing to get his/her hands soiled.
I will recommend looking into the Sipwise CE which integrates the good features of Kamailio, Asterisk and SEM.

There is also 3CX which is quite popular windows and cloud based PBX

Yeah, the only problem of 3CX is that it’s windows based :slight_smile:
Not sure if it’s used a lot as a SIP softswitch where WISP connects his customers, I saw it mainly as PBX office solution.

Hi Alex, im a 3cx professional and 3CX is now working in linux but that not the case, we need a solution where we can, provide to the residential customer and to the enterprise customer, because

Asterisk in general -, as I know there is a Radius addon to it. But I will try also to grab CDR directly from it, as a2bill was doing. - is ok Radius Addon Works fine but you need to make splynx a fully support of ASTERISK
Free PBX - - is just a PBX
Elastix - 2 - 3cx Linux - PBX
Kamailio SIP server - Kamailio SIP Server 1 - EXCELLENT
Bicom Systems - - I dont know

Otherwise, PortaSwitch, PortaOne and PortaBilling Entire Solution is offered as hosting in Telinta - but just a little problem, starting price is U$ 500.00 so for some one will be very expensive!

SIPWISE CE is a GOOD Platform too but i dont now how to manage it im a VoIP Professional and i want @theafricanpenguin contact me for verify about it

I second 2600hz kazoo as a carrier grade VoIP solution with a complete simple API ready for intergrations!
Happy to potentially contribute to this integration.

We use ASTPP billing for VOIP, it is freeswitch based.
I think integration with is the right route, it works with asterisk, freeswich kamailio and opensips

I tried few hours with sipwise, I gave up, all ratecards have to be converted in cents per second, while most of providers are giving rate csv files in Euros or dollars per minute.

Hi Alex, We are using Porta and was wondering what integration has been done and where I can get it?

Hi, Splynx connects to porta API, grabs calls for previous day including the rates/call prices. ISP’s customer can see all his calls/CDRs from Splynx client portal.

Then, 1st of each month Splynx generates one single invoice for customer where all Porta calls are included. Also when new number appears in Porta - Splynx displays a notification on the dashboard, so admin can match the PortaID to Splynx customer

Please contact to get more information or schedule a presentation call.

Hi…i am a new user here. As per my knowledge the evolution to IP telephony networks presents many challenges for rural service providers. That’s why REDCOM offers a complete range of hybrid and pure-IP softswitch solutions designed to help carriers reduce their reliance on obsolete systems, contain costs, capture new customers.

@alexcherry 3cx has a Linux distro. I have run the Linux ones severally over 9months now, very reliable. Am not a friend to windows. Please check on it it’s a very user friendly pbx.

@alexcherry how about driving your voice dev to a prepaid voice module rather than a post paid one?

@alexcherry how about integration with wholesale control panels? We use Telnyx for SIP trunks, DID numbers, etc. I would love to pull the CDRs directly from their API. I know many other WISPs who use Telnyx as well.
