HELLO & WELCOME

[cfcman]

My current setup is a Gigaset SL565 base station with five SL56 handsets and a Siemens HC450 Door System. I want to add VOIP to my setup, so have bought a Gigaset N300IP base station. The intention was for the N300IP to replace the SL565 as a base station, but I've discovered that the N300IP is not compatible with the HC450 Door System.
So....I'm left with the option of keeping BOTH base stations, and registering all of my handsets with both of them. The problem is that, as far as I can tell, each handset can only be connected to one base station at a time, meaning that an incoming call on one of the base stations will only be heard on whichever handset(s) happen to be connected to it at the time.
Is there any way of having incoming calls from both base stations routed to all handsets, regardless of whether the handsets are connected to the relevant base station?

Well unless I read it wrong, it states here that the HC450 is compatible with both the Gigaset Gigaset N300 IP and N300A base stations? Regarding your SL56 handsets, they don't appear to be compatible with the N300 IP base station. They may work, but with limited functionality.

Is your Gigaset N300 IP running the latest firmware? Try upgrading your devices firmware. Simply navigate to the Settings > Management > Firmware Update page and click on the "Update Firmware" button.

EDIT: FYI, my Gigaset N300A IP is running the following firmware revision: 42.245 (422450000000 / V42.00)

Thanks for the suggestion - there was indeed a firmware update available for the N300IP, which I have now installed. It has now successfully registered with the HC450. The issue now is that my five SL56 handsets, which I have also now registered with the N300IP, are not listed when I press the INT button on a handset. I would usually expect to see a list of all handsets connected to the same base station when I press INT. Instead, when I press INT on a handset I see a blank display with a line of 6 dots at the top.

As I pointed out above, your SL56 handsets are not compatible with the Gigaset N300 IP or N300A IP. If they work at all, they will only have limited functionality (make and receive a call).

Ah sorry I missed that. That's a pain - it means I'll need to replace all five handsets.
Any recommendations for a low-end (i.e. low cost) handset which will:
- work with the N300IP
- work with the HC450
- have full internal calling/intercom features
- selectable PSTN/VOIP calling on a per-call basis?

[WelshPaul]

@cfcman no worries...

Unfortunately, the HC450 isn't included in Gigasets compatibility checker, no idea why! But, going by the above, the Gigaset SL400H is compatible with the HC450 door entry unit, it supports Internal calls, intercom, but i'm unsure if it supports selectable PSTN/VOIP calling on a per-call basis (it should). The Gigaset compatibility checker confirms full compatibility between the Gigaset SL400H and the N300 IP base station too.

It's available on Amazon here. Not cheap mind, £81.99 FREE UK delivery each. Maybe order one and give it a try? If it doesn't work, send it back. :)

[cfcman]

£81.99? Ouch! Unfortunately I can't blow >£400 on new handsets :0(
Thanks for the list - I'll trawl through it and see if any of them are a little more reasonably priced.

[WelshPaul]

Yea, was thinking the same when writing my reply! :x

It's the only one that I can confirm works with both the HC450 and N300 IP base though. :dunno:

Might be worth contacting Gigaset support and ask them directly what handsets are compatible with the above as their online compatibility checker doesn't list the HC450? Their UK telephone number is +44 (0)20 369 53111, can't find an email address for them though. http://www.gigaset.com/en_en/cms/servic ... tline.html

[cfcman]

That's really helpful - thanks. I'll contact them tomorrow.
Sadly I haven't had the best experience with Gigaset support in the past - prior to purchasing the N300IP I asked them whether it was compatible with the HC450 and they weren't able to tell me!

[WelshPaul]

I just found this list at http://www.gigaset.com/en_en/cms/servic ... hc450.html

• Gigaset SX810A ISDN

Other base stations such as Gigaset SX353 ISDN or Gigaset SX255 ISDN do not support the OPCAP protocol and are not compatible with the Gigaset HC450.

Compatible handsets:

• Gigaset C430H
• Gigaset C47H
• Gigaset C59H
• Gigaset C610H
• Gigaset C620H
• Gigaset CL540H -Dune-
• Gigaset CL750H
• Gigaset E45
• Gigaset E49H
• Gigaset S1
• Gigaset S1 color
• Gigaset S44
• Gigaset S45

• Gigaset SL1 color
• Gigaset SL37H
• Gigaset SL400H
• Gigaset SL55
• Gigaset SL56
• Gigaset SL74
• Gigaset SL78H

Other GAP supporting handsets, also from other manufacturers, can be used for the voice connection to the Gigaset HC450, but not to open the door.

So look through the list and make sure whatever you shortlist is compatible with the N300 IP basestation by using the Gigaset compatibility checker located here: http://www.gigaset.com/en_en/cms/servic ... ducts.html

I recommend the Gigaset C430H (I use the C430HX). It's available on Amazon here and it's more reasonably priced at £32.99 (FREE Delivery in the UK).

[cfcman]

Actually I don't need the handsets to open the door - just to ring when someone presses the doorbell. The C430H looks much more acceptable price-wise - I'll track down a manual online and see what it can do.

[WelshPaul]

Just be aware, when using a non compatible handset with the N300 IP, it will result in many of the features and notifications not working. So, even if you don't want one to open the door, get one that's compatible with the N300 IP regardless.

Good luck

Their UK telephone number is +44 (0)20 369 53111, can't find an email address for them though. http://www.gigaset.com/en_en/cms/servic ... tline.html

I do love how Gigaset put the number it should read: +44 (0) 20 3695 3111 for international, and 020 3695 3111
