Jack Noe Posted March 8, 2018 Report Share Posted March 8, 2018 Hi all. I have an issue with a Door Bell connected on 2600. When the door bell rings the phones it will receive the DTMF the phone sends. But when the phones calls out to the doorbell, the door bell will not recognize the DTMF received. Any Experience with this ? Thanks Link to comment Share on other sites More sharing options...
Logicwrath Posted March 8, 2018 Report Share Posted March 8, 2018 I have no experience with this. However, you may look into the different DTMF types being used by the phones calling the doorbell. RFC2833 vs INBAND etc.. One of the types I think INBAND will blast the DMTF audio on the same audio channel as the caller. You may try different settings on the phone calling the intercom to see if it helps. Link to comment Share on other sites More sharing options...
esoare Posted March 12, 2018 Report Share Posted March 12, 2018 @Jack Noe Which type of Door Phone? Link to comment Share on other sites More sharing options...
SPC-Tim Posted March 12, 2018 Report Share Posted March 12, 2018 @Jack Noe We had issues with a doorking https://www.doorking.com/telephone/1802-entry-system We ended up having to connect it to a cisco 112A adapter, and programming in a dialplan with the code to open the door. Can you confirm what kind of doorbell it is? Link to comment Share on other sites More sharing options...
tomas_ Posted March 13, 2018 Report Share Posted March 13, 2018 ATA-adapter doesn't sound like a 100% good solution... Did you take a look at Grandstreams door systems?http://www.grandstream.com/products/physical-security/video-door-systems Link to comment Share on other sites More sharing options...
Jack Noe Posted March 26, 2018 Author Report Share Posted March 26, 2018 As per 2600, and our testing. A page goes through a conference bridge, so DTMFs will not be passed through a page group. So you have to call the device, and then the DTMF will come along, if its set for auto answer Link to comment Share on other sites More sharing options...

I have a client with a very noisy front door area (across the street from an outdoor train station) and the noise off the Axis video doorstation is overbearing, even with noise cancellation enabled Does the grandstream offer noise cancellation?

tomas_ Posted March 31, 2018 Report Share Posted March 31, 2018 No, unfortunately not. Only tested Fanvil but don't now anything about noise reduction. I wilk ask out distributors if they can recommend something. Link to comment Share on other sites More sharing options...
Olaolu Abiodun Posted March 31, 2018 Report Share Posted March 31, 2018 How was the Fanvil? I have one but it kinda felt cheap for the client, so I went a different direction and never installed it. Link to comment Share on other sites More sharing options...
tomas_ Posted April 4, 2018 Report Share Posted April 4, 2018 Oh, I'm sorry but I didn't install it nor used it personally. The customer is rather far away so we had an local electrician there to install it for us. I haven't heard anything about it from the customer and he says it's working OK...
