When it comes to Los Angeles (LA) business VOIP, the way businesses access the internet can make or break voice quality. In a word, while many ISPs market T1 and T3 lines that are supposed to be ideal for VOIP use, many of those are glorified DSLs, which do not have the qualities necessary to make them highly desirable for VOIP applications.
Voice quality is entirely dependent on the way that data is transmitted over the line. Voice data needs to be transmitted smoothly to create coherent speech, and it needs to be given priority over data access when the line is shared with other transmitters of data: computers hooked up to the internet, for instance. The former quality, committed information rate (CIR), needs to be close to 100%, so that data is continuously ‘flowing’ through the cable at an even rate. What’s more, QoS or “quality of service” needs to allow for voice to take applications to take precedence over data applications so that the stream of voice packets is not interrupted by data. Because DSL does not have a CIR, it cannot have a QoS, and it is therefore not an good connection for businesses that demand high quality voice transmission out of their voice service.
Since real T1 and T3 lines have near 100% CIR and QoS, they will provide clear voice, especially in conjunction with a SIP trunk. But some would-be Los Angeles (LA) business VOIP users are often lured into buying T1 or T3 lines that are nothing more than DSLs with greater bandwidth – connections that don’t offer a CIR and therefore don’t offer high-quality sounding voice.
Businesses thinking about implementing business VOIP should make sure that the Los Angeles (LA) ISP they deal with is selling them a real T1 or T3 connection that has the qualities necessary to transmit high-quality voice. While it can transmit voice, DSL’s combination with VOIP results in what some call “very bad cell phone reception” – not what customers and partners want to hear. Buying internet access from a trusted ISP that installs and oversees its own lines will ensure that the line is suitable for voice applications.
The results will translate into tremendous savings on all phone calls, as the cost of incoming and local calls is eliminated, and long distance is billed at a rate of only pennies per minute: cash every business could surely use in this economic climate.
