I have been using it from few years and no complains so far.

1- Its diffidently great cost saving for business. 2- Easy to use. 3- Excellent voice quality.

Support sometime takes long time to respond but overall would say none so far, it works as expected.

Siptrunk enables us to resell a hosted voip solution and keep track on the financials for each customer.

Very reliable service. Very easy to setup with FreePBX/PBXact. Customer support was great both during initial setup and then setup for our customers. Website for setup is great and very straightforward.

Billing. The requirement to have a credit card on file for overages. Not being able to provide our customer with a detailed invoice on overages. Also not being able to pay on net terms is a big drawback.

SIP trunking is a complex technology and Siptrunk makes it easy to get started and reaping the benefits of VoIP quickly and lasting.

The price point may be relevant for the U.S. but adding 20-30% exchange rate upcharge makes not viable, at least not for my business, to keep it in our portfolio.

Became a reseller of SIPTRUNK in April 2020 and never thought of changing to another provider thus far. They not only offer precise and expert support, they deliver it too. Everyone can offer cheap call rates, not all can offer the support like SIPTRUNK.

The ability to view the clients CDR's without the need to log a ticket for them to compile the info and send it through. Being in full control of each Trunk, DDI, Pricing Plan and seeing LNP progress. Commision being paid for being a reseller is always great too. Even though iSIP is based in South Africa , SIPTRUNK is still offering the same support, pricing plans and great service to our American based clients. They understand the importance of Telephony in a business.

I would consider allowing an option for a reseller to be able to run and capture live calls on the network. Between the client and SIPTrunk. I understand that there is a security concern on this as one will be able to see alot more behind the curtains then. Alternatively, being able to see more details in the CDR's already provided. MoS scores, Call termination reasons, Codec used, Received/Transmitted Packets, RX Maximum Delay. As this will ease some support queries from your helpdesk as well.

The siptrunk service works as expected and when i have had technical issues( related to customers equipment) customer support has always been excellent.

It is easy to Use the Siptrunk.com portal to manage separate customers all under one interface. I like that The individual customer facing portal is brand-able so my customers see my logo there.

at times It can be a little difficult getting all of the information sand forms together for porting a customers existing number over to Siptrunk.com but this process is the same for all carriers and really isn't a big deal once you have done it a few times. it would be nice for scheduling purposes if it were possible to be able to do all of the parer work and get approved for the porting and then have it so you could do the actual cut over by clicking a button in the portal but Im not sure that would work out with having to move the info from one service provider to another.

They have done an excellent job, we have always been happy with each new setup.

Unlimited, yes, unlimited. I don't want to calculate customer minutes and usage. The new model is all-in and that works great here. The stuff just works.

Faxing over their trunks does not work and they state that. It would be nice to be able to have that service work.

Have had very, very few issues and those that I did have were resolved within acceptable times. I especially appreciate being able to call where others will only accept tickets.

Ease of use, intuitive layout, speed of provisioning and DID acquisition

The inability of being able to allow more than one login per account.

Most stable SIP trunking I have used so far. Support is quick and helpful and automated alerts are useful. I also like the fact that they give you a primary and a failover trunk to utilize. It's also great that they are 3CX approved.

Faxing services are little expensive. Not a big deal if you dont send/receive a lot of faxes.

Exceptional service

Reliability sone of the main features of the service

Could improve the web interface on some pages like choosing DID's

Simple admin interface, quick provisioning.

We would like to be the billing contact for our clients.

Siptrunk goes out of their way to ensure their customers are happy. Service does not go down and they actually answer the phone unlike a lot of their competitors.

With over 4 years of using SIPTRUNK Services we have never experienced any down time! Whenever there have been configuration issues the support staff drops everything to help you.

Using the SIPTRUNK system for over 4 year I can find nothing that I do not like, nothing. It just works.

I have been using SIPTRUNK for over 2 years now and it has been a great provider for my VoIP services as well as those for my clients.

Their software is easy to use. It has white labelling for my company information being sent to clients. They have a solid knowledge base to support setup and usage.

I do wish the text messaging service could integrate with 3cx but I also understand why it can't.

The ability to manage all of your SIP trunking needs through a well designed self-service portal. No more phone calls or waiting days to have simple changes made. Updates are realtime through the portal.

No telephone support. They are responsive to emails, but sometimes you just want to be able to call someone.

My overall experience is outstanding. My customers love the service. I love the service. I won't use anyone else.

Sip service from siptrunk.com is incredibly easy to setup. Its reliable, it's cost effective, and the support is outstanding.

I have nothing negative to say about siptrunk.com

Great value for the customers, outstanding call clarity works with most customers needs

Ease of setup,flexibility, call clarity, and awsome tech support . The value for the service was by far better. Not the cheapest around but you get what you pay for

The only con was the old web site, it was hard to navigate but the new updated one is easy and more user friendly

Had multiple sites and customers scattered between T-1 lines other sip providers with less features. I have migrated many customers without issue

When I first signed up I was a little skeptical but now I've been a customer for years and the service is great. Customer support is speedy and constantly adding new features

None really any issue I've had was resolved very quickly

My clients are finding SipTrunk easy to work with and bill is always correct.

Easy software to work with and tech support has been very helpful.

No complaints for the past 3 plus years.

The advantage of SIPTrunk is the ease at which you can setup an account and be online in just minutes.

When a customer goes over their monthly allotment of minutes they don't roll over into the next higher tier plan automatically so the account has to be constantly monitored and then the plan changed manually.

Once the Trunk was configured to my PBX, it was hassle free and almost ran itself.

Not I an think of when it comes to the cons of the software.

How easy it was to setup and use. Did not have to be a technical person to use it.

I have no cons at this time with Siptrunk software

Very easy to setup and configure. Very quick to get up and running

Nothing that I don’t like about siptrunk.com

Self administration is easy to use with immediate changes

There's nothing to not like about siptrunk.com.

I started using it a few months ago and my usage has continued to grow with great success. Looking forward to a long business relationship.

Simple to use with a lot of features to accommodate my needs.

Sometimes the billing can be a little confusing. I'd like to see the DID search improved so that I could find a phone number based on what the alpha spells out verses having to search through each city to see if the number is available.

Managed services provider with over 100 trunks.

The service is incredible. Always have a fast response and quick resolution. Makes me wish I had more issues!

Too few issues. Not enough opportunities to speak with the great support staff.

Its ease of use. I can have a client's SIP service (including DID selection) up within a matter of minutes. And we have full control over number inventory, 911 locations, monthly plan changes, etc.

Support documentation. I have had a number of issues getting SIPTrunk to work consistently with our preferred PBX (Grandstream). SIPTrunk's documentation is greatly outdated.
