I implemented a VOIP system in our office a few months ago, and no matter what I try I just cannot get it to work correctly.
We have problems with:
- Phones on call groups continuing to ring after one has been picked up (happens a lot). This has even culminated in us picking up one of the ringing phones to silence it and having the line continue to ring down the handset to us!
- Failure when trying to pick up another phone that is ringing.
- Delayed audio when picking up a call.
- BLFs working intermittently.
- Inability to transfer calls (a new, recent problem).
We don't actually have any problems with the quality of the calls, and when they connect then they seem robust and don't disconnect etc, but these others problems are seriously affecting our ability to trust the system.
Our hosted VOIP provider blames our router (Draytek 2830n) but another provider said that is the router they'd want us to have if we move to them so obviously it is capable. Or they blamed our managed switch, so we now have a HP 24 port unmanaged switch, with no change in the issues. The phones are Grandstream GXP2130's on the latest firmware, with one SNOM 320.
I am not an IT guy and have done what I can using Google, but now have reached the point where I think the only way to get this working correctly is to get a VOIP engineer in to try and optimise everything. If I google for one though I either get job adverts or VOIP companies who have engineers who will only help if you move your system over to them.
Does anyone have any recommendations for independent companies/engineers in the Midlands/Northamptonshire area that we could contact and get a quote from to look at our setup?
