Grandstream GXW4104 to Grandstream HT814 Via 3cx

[mendel@myglobalsecurity]

Hi,

I have a school that has 4 PSTN lines connected to a Grandstream GXW4104, they have the 3cx PBX set up on-site with sip trunk setup for their IP phones however they have 4 Analog phones that the students can use and they do not want it to run through
the sip trunk. However, they do want me to schedule when the kids can use the phones.

I have the analog handsets connected to a HT814.

I have set 4 extensions in the PBX and have configured office hrs for them as they requested.

Right now I have the calls coming in to the PBX and they should be routed to the correct line however the outbound calls are not working.
When I pick up the analog handset I get a busy tone.

The schedule is not working on the phones as set up.

I tried following all the guides and reaching out to support but they say they do not support gateways anymore.

I'll give you a little insight into the setup.

On the GXW I have Unconditional forwarding set up as follows

USER ID, ch1:1845xxxxxxx;ch2:1845xxxxxxx;ch3:1845xxxxxxx;ch4:1845xxxxxxx;

Those are equal to the DID's I have set up in 3cx.

Under User Accounts, set as default Channel 1-4 User ID 10000 Authetication ID 10000 etc.

The HT814 is just provisioned to 3cx and has the extensions set up in them

Thanks in advance

This happens once you pick up the handset or when you dial out?
Have you run captures to check from where the busy tone is coming?

It happens once I pick up the handset.
I have not run a capture yet. I will be back on site at some point this week and will upload any if I dont have it resolved by then.

Let us know however this seems to be an issue with Grandstream.
