Over the last few years calling card business have been very competitive. Customers have too many options. Companies have to pay for origination, termination, manage the systems networks. With all these expenses it has become very competitive that directly affect your profits. We have noticed the termination cost going down quite a bit over last few years and most of the companies get good deal on termination. But still lots of people are paying too much for origination.
Some of our customers switched to didforsale and saving lots of money every month. We offer Inbound Virtual numbers specially designed for calling card companies and call centers. Our flat rate inbound DID are just $8.99 per month. Each DID comes with 20 channels where 20 people can call at the same time. Normally a good calling card company takes 50 to 300 numbers and uses 400 to 2000 simultaneous channels. So lets take an average of 150 numbers and 600 channels.
Your cost at DIDforsale will be $8 x 150 = $1200 + tax per month. You don’t have to pay anything extra, no per minute charges and no per channels costs. While other VoIP service providers charges very low cost on the DID but charges very high price on per channel cost. Based on our research average market price is $1 per DID and $12 per channels. So the same company with 150 DID and 600 channels will be paying:
150 x $1 + $12 x 600 = $7350 per month.
Compare the prices $1200 vs $7350.

If you are using VoIP (Voice over IP) then at some point you must have to troubleshoot the call flow to find where the problem is. There are many tools you can use. To teach you exactly how to use a protocol analyzer is beyond the scope of this material; however, we will give you some tips on analyzing SIP and RTP packets. Bear in mind these tools can do much much more than what I illustrate here. I will be using these tool just to capture VoIP traffic.
Most common used tool are: Ngrep, Wireshark, TCPdump.
Ngrep:
We often use ngrep to monitor our VoIP services, because it is very simple and light. If you don’t have it installed, then you can download it from this link
http://yum.trixbox.org/centos/5/old/repodata/repoview/ngrep-0-1.45-1.el5.rf.html
http://yum.trixbox.org/centos/5/old/ngrep-1.45-1.el5.rf.i386.rpm
This command will capture everything on SIP port (I know this can capture any network activity, but I am using it for VoIP on SIP ) and dump the data on the screen. Easiest way to know how your system in interacting with your vendor or client.
See everything on your system on SIP protocol.
ngrep port 5060
If you want to filter the traffic based on phone number
ngrep ‘9498859944’ port 5060
If you want to filter traffic based on IP address
ngrep ‘IPAddress’ port 5060
Example
ngrep ‘209.201.2.255’ port 5060
Other important options
-t Print a timestamp in the form of YYYY/MM/DD
-T Print a timestamp in the form of +S.UUUUUU, indicating the delta between packet matches.
Example
ngrep -t ‘9498859944’ port 5060
ngrep -T ‘9498859944’ port 5060
As I said there are lot more options read man pages ‘man ngrep’, but this is good enough to see the call flow on your system.
