IP door Bell

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

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.

ATA-adapter doesn't sound like a 100% good solution... Did you take a look at Grandstreams door systems?

Have you personally tested the grandstream? If so, any feedback?

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?

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...
