I have an issue with my GDS3710: the device cannot open the door when I press the digits on the phone.
I configured extensions for the GDS3710 account and the other phones, and I set the DTMF signaling to RFC 2833. I also configured the phones to use AVT for DTMF. I can successfully make calls from the GDS3710 to my phone, but when I press the digits on the phone, nothing happens and the door does not open.
I checked the configuration and I am sure that Asterisk is sending the DTMF message with the digit “1” (which I configured for tests as the remote PIN number) to the GDS3710, but the device does not respond and the door remains closed.
Here is some Debug info.
Here is when i configured it on RTP 2833 that is recomended in my device:
[2026-07-30 10:07:24] DEBUG[22525][C-00000006]: res_rtp_asterisk.c:6071 process_dtmf_rfc2833: - RTP 2833 Event: 00000001 (len = 4) Got RTP packet from 192.168.10.28:16440 (type 101, seq 010378, ts 379647220, len 000004) Sent RTP DTMF packet to 192.168.10.9:5008 (type 101, seq 041135, ts 379647520, len 000004)
The ips are random i dont want to leak our company ip structure but the ports are real.
Im sure the Asterisks is correctly sending the “1” that was the test remote pin to DTMF but doors are still locked.
Also i changed everything to SIP INFO and the result are the same.
