[cisco-voip] Helios IP Uni intercom units Dual Button.

[Matthew Collins]

Just to close the loop.

Helios have come back and said that their IP Uni intercoms are not designed to call between other IP Uni intercoms. They are designed for use between a Helios IP Uni intercom and a normal phone.

They recommend their Verso and Vario intercoms for our clients.

Hi All,

Just a quick follow up. I managed to get some support with a little white lie. I emailed sales and said we were thinking about purchasing 50 more devices but unable to get two test units working. Surprise surprise I had a engineer on the phone within an hour.

Helios said two intercoms should work together but no one within the tech team had ever deployed or tested it. They are able to reproduce the issue and are working on a firmware update to fix.

Regards

Thanks for your reply's Mike and Neal,

We have hard coded the voice vlan as they were booting in the data vlan. From the traces its not looking like a network issues with qos ect.

Yes they register to the a CUCM system as 3rd party sip end points.

With regards to locations they are either side of a pair of 2 way airlock doors so there is no chance of getting feedback from each other. I did test two devices between different floors to completely rule this out but there was still issues.

Mike I think you may be right about the speakerphone logic as calls between a intercom and a desk phone are ok. Just annoying Helios point blank refuse any support.

Regards

Matthew Collins

Matthew - "The phones are registered and they can place calls between each other."

Are they actually meant to be used that way?

Sounds to me like the speakerphone logic is getting confused and/or sucks. E.g. the speakerphone logic on one side makes adjustments, it confuses the speakerphone logic on the other side, causing it to also make adjustments, which makes the first side readjust, etc. etc. Could be that they are meant more for calling a standard handset and not really meant for calling each other. Just a guess.

Furthermore, are they within "earshot" of each other? 'Cause that would definitely cause feedback and weird speakerphone behaviour.

Hi all,

I have been asked to configure some Helios IP Uni intercom units and register them to the CUCM, I have been able to compete this, The phones are registered and they can place calls between each other but the audio quality is poor, and when I say poor I don't mean packet loss but the Audio volume keeps getting higher then lower, There is a lot of feedback. I might get 10 seconds of clear audio then its all start to go bad again. I have tested lots of the audio settings but not been able to get the right combo. I have also upgraded them to their latest firmware. I'm unable to log a call with Helios for support as we didn't purchase them direct. They are telling my to do to the supplier, But we are unsure where they were purchased from.

Any thoughts? What was anyone else's experience, Did they just work out of the box without tweaking the audio settings?

Thanks in advance.


Matthew
