GrandStream HT813 - Apartment Alarm for VoIP, FXO, FXS Assistance
Hello, my situation is similar to yours. I reside in an apartment building with a buzzer that can ring your landline phone. My goal was to extend it so it also alerts my cell and my wife's phone when we're away. I followed the guide from Ryan Steele and it functioned well at first. But recently the device stopped working, so I switched to a different VOIP system because I didn’t want another SPA3000 to fail. My needs included VOIP functionality plus FXO and FXS ports to route calls properly. I also wanted to avoid paying over $20 a month for a landline that only forwards calls to my cell, and I needed the ability to group calls across multiple devices. I ended up buying the GrandStream HT813. After setting it up and testing, the FXS port worked perfectly, but the FXO profile wasn’t forwarding calls to my phone—it went straight to the FXS device and rang. Both ports indicated they were registered, confirming they connected to the VOIP system. Someone with experience might have a tip on how to resolve this issue. I also attempted the "Unconditional Call Forward to VOIP" feature, but it didn’t help. The FXO port’s status changed from "Idle" to "Not Connected," yet I haven’t interacted with it.
I'm experiencing the same issues as the others with the SPA3000. All the models available right now appear to be fake. I tried three of them, and they all performed well for a short time before failing. It's a shame since the setup was straightforward and it worked nicely. I'm considering the HT813, but most people say it's difficult to set up...
I previously had the SPA3000 functioning but it ceased operation after a few months. I’m now using the Grandstream HT813 and will share updates on its setup with VOIP.MS to forward calls to my cell. If you’re still interested in getting it configured correctly, feel free to reach out. Update: It’s working now—let me know if you need help.
The HT813 functioned correctly in just a few moments. It was easy to configure.
Hey there, I'm working on matching the same outcome with grandstream 813. Could you help me set up the FXO configuration? I'm following the sp3000 manual but the choices seem quite different. The voip.ms site doesn't provide guidance for ht813 either. I've set Dial Plan 8 to (S0<:1xxxxxxxyyy), where the numbers after the colon are your virtual SIP number—your main username and the three-digit code you picked. For grandstream HT813, it doesn't support dial plan 8; it only has a single dial plan. I've adjusted PSTN Caller Default DP to 8 and set the answer delay to 0. Additionally, I need an option to connect a VOIP number to a PSTN bridge call so a guest can ring the buzzer system. The goal is for the guest to call the VOIP number, and I want me to send the correct dial pad number to the buzzer to open the door. We have a buzzer gate at the townhouse community, and the guest must exit their car to trigger it.
I don't understand why you want this old discussion back. Could you share the right format for the Dial Plan of the HT813?
With FXS enabled and FXO disabled, your landline functions properly. Previously using the old equipment confirms VoIP.ms is configured correctly. You can place calls from the landline to your VoIP setup, but when you ring in, the landline only rings without sending the call to your cell group.
I'm working to get everything functioning and need the precise adjustments. I previously set the caller ID for the sub account to a verified caller ID (my mobile number) and configured Grandstream to unconditional call forwarding to a virtual DID that routes to a ring group. It seemed to work twice, and I noticed my voicemail was picking up through the buzzer—possibly because calling from your own phone accesses it. I'm still stuck and would really appreciate any guidance.
