subject: SIP Dialer Traffic - Why Most SIP Providers Don't Want it [print this page] Many SIP Termination providers do not like to have too much (if any) dialer traffic. One of the reasons is that early 2009 many of their downstream tier one SIP providers started charging additional surcharges and penalties if the average length of the calls is too short, or if many calls do not complete.
Dialer traffic often has a very short ALOC (Average Length Of Call). So each call does not last very long and does not generate much revenue for the SIP termination provider.
Additionally dialers often make very many call attempts, clogging up the switches.
Because each VoIP call takes some time to set up this is non billable, dead time.
These calls are also far less likely to be picked up, and when there is no answer there usually is no charge and thus no revenue is being generated. So nowadays most SIP termination providers do not even want to take dialer traffic.
When chosing a provider, make sure that you are aware of what the surcharges are.
Ask if there is a minimum requirement for the following:
* ACD (Average Call Duration) also referred to as ALOC (Average Length Of Call)
* ASR (the ratio of calls being answered)
* Is there a maximum percentage of calls that are shorter than 6 seconds
It is also a good idea to check if you can get the CDR log files with a few days worth of data. With your CDR you can determine the actual statistics and traffic patern for your calls so that you can be sure that you meet the minimum.
