SIP Trunks the Market
Posted on 23/01/2012 @ 3:03 PM
Ofcom records state in Q2 of 2010 33 million ISDSN and PSTN business lines are installed in the UK so the market place for SIP is massive if the churn was only 50% over 5 years that’s 250,000 channels a month.
No technology has been an overnight success; ISDN took 10 -15 years to be fully accepted in the UK, the service was originally sold as a voice and data offering, the data side soon dropped being far too slow and complicated.
To be fair to the incumbents, if I had invested millions of pounds in buying and million pounds in maintaining ISDN exchanges, I would also be sweating the assets for as long as possible.
To use SIP Trunks you need a good data connection. For sub 10 SIP Trunks ADSL2 and ADSL2+ is a cost effective and reliable service with the same Service Level Agreements (SLA) as PSTN or ISDN. For larger installations EFM is the true alternative to ISDN30, EFM has two services one offering up to 10Mb the other up to 20Mb providing you with the ability to route voice and data cover the same circuit. EFM is supplied with a standard SLA of 6 hour response 24/7 with blows the ISDN SLA out of the water.
SIP is an application running over a data connection. Due to this alone it’s far more flexible than ISDN. Being cloud based, inbound calls can be routed worldwide. Unlike ISDN which has a set amount of features (ETSI standards). Each SIP carrier provides different features and applications. A simple application such has outbound CLI may not be supported by some SIP carries or restrictions may apply. On the whole, though, the features and application provided using SIP far out way the features supported by ISDN. That’s evolution.
Data connectivity and more importantly the confidence and understanding for data connections has grown significantly over the 6 years Voiceflex have been supplying SIP trunks.
