COVID-19 has opened the world’s eyes to enhanced collaboration tools and mobility solutions, accelerating the pace of the ISDN and PSTN phase-out. If you are considering this migration, we can offer you subsidised migration services for this transition.
ISDN has been a standard for so long, which might raise concerns for you when considering moving to a new service. You must have completed your migration to SIP from ISDN within the next five years and now is a great time to get the migration underway, here is why:
With SIP, you can use your existing planned or dedicated connectivity at a much cheaper cost. We know that this is a difficult time for businesses financially, so every penny counts and this migration can help you save. Rental fees for SIP are also cheaper, usually costing £5-£10 per channel, rather than £15-£20 with ISDN. Plus, you will have access to free calls between sites that are connected on a network, locally and internationally.
ISDN offers up to 30 channels, whereas with SIP, you can have up to 2,000 channels on just one connection. There are no limitations on DDI (DNS, DHCP, and IPAM) ranges. With ISDN you could only increase or decrease your channels with Open Reach planning, requiring a new bearer for additional channels, this is not the case for SIP. SIP can expand and reduce your channels instantly.
ISDN also has many limitations with regards to flexibility. For example, you could only use local geographic pre-fix numbers from the local exchange; with SIP, you can use any geographic and international number. SIP can be diverted instantly and can divert by DDI, rather than being diverted by network provided. These are all crucial factors to consider, given the current circumstance. With SIP, you are far more flexible to transition to remote working if you need to. Finally, the lead time for ISDN installs could be up to eight weeks, we can deliver SIP instantly, depending on your current connectivity.
