VOIP and B&O phones

[JASON B]

Hi all,

I have a PSTN Base that has a couple of 6000’s and a 2 attached. I also have a 1401 connected to a separate BT socket in case of power failure.

Problem is when I want to use the base with VOIP. As per a different thread here: https://forum.beoworld.org/forums/topic/beocom-6000-and-virgin-voip/ I have the same problem where an incoming call is dropped immediately (outgoing works fine) and I’m using a Cisco SPA112, the same as @keith_saunders uses though mine is with voipfone.co.uk.

When I connect the 1401 it all works fine so it would appear the base is the problem.

Earlier comments provide a solution when using a VOIP adapter to ensure you’re using a 4 wire RJ11 to BT adapter to connect the base to the VOIP adapter. I see that the RJ11 to BT adapters that come with the SPA112 seem to be 2 wire, so I presume these could be a problem? However, my base station cable has an RJ11 to BT adapter on it, so if I remove this I can plug it directly into the SPA112 via RJ11 and bypass the adapter altogether. This doesn’t help – same situation with incoming calls dropped. Whilst I see some have managed to get this to work I wonder if obtaining a 4 wire adapter will help when considering I can plug the base into the SPA112 directly?

Are there any settings applicable to the SPA112 to work with the base?

Any thoughts please?

I don’t yet have VOIP, but I just checked my Beoline base and note that its RJ11 connector only has two-wires connected (to pins 3&4) .  In my case these go via an adaptor to pins 2 and 5 of the BT master socket.

Given that the RJ11 connector on B&O basestations only has two wires connected, I don’t see how a ‘4 wire adapter’ will help.  As far as I can see the only other connection variation is to ‘reverse’ pins 3 and 4.

Have you tried the VOIP adaptor and base station without the BeoCom 1401 connected?

I assume that you have googled the problem but have you seen the following ‘AI Overview’ suggestion?

AI Overview
 
If a Cisco SPA112 is dropping incoming calls, you can try changing the waveform type:  
Log in to the Phone Adapter Configuration Utility
Select Voice then Regional
In the Ring and Call Waiting Tone Spec area, select an option from the Ring Voltage drop-down list
In the Ring Waveform field, change the waveform type
Click Submit to save the configuration

Thanks Guy,

I’ve recently received a reply from Voipfone technical support after I explained what kit the SPA112 is connected to and they wanted to make sure I am using an RJ11 to BT socket adapter that includes a Ring Capacitor. I’m not 100% sure what mine are (came with the SPA112 so could be US), so have ordered some from a link they supplied:https://www.amazon.co.uk/gp/product/B000Q4X9PS/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Looks like many on amazon don’t contain the ring capacitor.

I haven’t used the 1401 at the same time as the base station as I haven’t put a splitter on the adapter. Voipfone support spent quite some time checking/configuring the SPA112 so I doubt I can make a difference with changing the settings but I’ll see how the new adapters work first.
