Are you struggling with poor call quality between branch offices? Do you keep losing calls halfway through a conversation? Are expensive leased line charges crippling your business?
Before upgrading your bandwidth to improve quality or taking out your VoIP system altogether, you need to optimise what you’ve already got. Deployed between offices VOIPBOX gives you all the benefits VoIP promises without the headaches.
More lines + high call quality
Patent pending QoS and compression technology dramatically reduces the bandwidth required by VoIP traffic and guarantees voice quality by giving it priority over other data. In fact VOIPBOX is so efficient that you can now support 28 simultaneous G729 calls over a 256K data link rather than the three that are normally possible.
Save money on leased lines
Carrying more calls over low cost ADSL links saves you money because you don’t need expensive leased lines between your VoIP enabled PBX and remote office locations. If your sales or helpdesk team are growing rapidly and you need additional lines VOIPBOX can bond low cost circuits to give you T1 capacity for ADSL prices. Over the life of your new iPBX VOIPBOX could save you tens of thousands of pounds in expensive leased line costs.
No more dropped calls
If you’re concerned about call reliability, don’t be. VOIPBOX failover features give you ‘peace of mind’ by automatically switching over to any available backup links so you don’t lose any calls in progress.
Whether you have a single connection between two offices or more complicated multi-site, multi geography links, VOIPBOX makes VoIP work better.

"SpiriTel looked at VOIPBOX as a solution to provide additional channels of VoIP capacity for sites that had limited available capacity or where the cost to provide that capacity was too prohibitive."
