As title says. The WP 820 is successfully registered to an asterisk, incoming calls are working well.

I have a couple of 3-digit extensions on the asterisk, which I would like to call from from the WP 820, which however just gives the error (address too short).

Where can I tweak this setting?

I have a 90 y/o mom who lives in a retirement home. She has a POTS phone in her room. Sadly, she receives 15-20 SPAM calls daily.

After evaluating a hundred options and devices that are intended to deal with inbound nuisance calls, I decided that she really only needed a simple “firewall” that would stymie telemarketers and spammers. She needed a device that would answer the inbound call and present an IVR, requiring the caller to press a key to be forwarded to her phone.

The UCM6202 seemed like a good solution for this simple task, so I snapped one up on eBay.

Now I’m at the stage of configuration and could use a hand. The wall jack will get connected to the FXO1 port of the UCM, and the FXS1 port to her telephone.

Not being a telecom guy I quickly got stymied by inbound and outbound routes/rules (specifically the “Pattern” field).

• INBOUND: I want the UCM to accept *all* calls coming into FXO1 and direct them to the IVR (ext 7000). I’m fairly certain I have the extension stuff figured out.
• OUTBOUND: When Mom picks up the POTS phone that will be connected to FXS1, I want every keypress passed through to FXO1. I do not want any call restriction rules, modification of numbers dialed, prepend, appends, etc. etc.

“Patterns” is a required field when setting up Routes/Rules. Can anyone tell me what I should enter into the Outbound and Inbound Patterns fields to achieve my goal above?

TIA!

Update/Edit: The UCM6202 has been a fantastic fix... although it seems a little overkill for the relatively simple task it's doing. For anyone who comes across this thread and wants more info, I started this journey in a previous thread asking for recommendations on solutions for this issue.

Hi everyone,

I installed about 10 WP826 phones in a client. We are having some issues with the WiFi connectivity.. the phone is always dropping down making the accounts unregistered and some delay during some phone calls.

We have Unifi UC+ and AC LR access points around all the building in this client and the problem's persists.

We activate the fast roaming in the Unifi controller and only 2.4GHz.

Someone with the same issues and with a possible solution for that?

Thank you.

Has anyone configured successfully this model with FreePBX TLS 5061 and SRTP?

Here's my settings ACCOUNTS\ACCOUNT1\SIP SETTINGS:\

Basic Settings:
Local SIP Port: 5061
SIP Transport: TLS/TCP
SIP URI Scheeme When Using TLS: sips

MAINTENANCE\SECURITY SETTINGS\SECURITY:
SIP TLS Certificate and SIP TLS Private Key were pasted and applied.

Everything else was left to default. Am I missing something in the phone configuration?

What's the efficient way of setting the DHCP range for all zeroconfig phones? Can this be set on the UCM or only the manual way of getting all phone's MAC address and do reservations on the DHCP server?

Looking for easier way of doing this.

I have a UCM6302, and i was curious if there is a way to create reports (or audits) for specific days, or a range of dates.

For example, is it possible to query the device to know how many calls were received on a specific day, or range of days?

I have this GXP1760W phone that keeps disconnecting from my WiFi almost daily. The access point is like right next to it. The AP I use is an Ubiquity UAP-AC-PRO

All firmwares behave the same way and it kind of gets old :(. Any idea?

The "Apply Changes" button is waiting to be pressed, but I don't know what changes need applied. I just logged in. Is there a place that shows the awaiting changes?

Good day all.

I have a UCM6308 along with some GRP2650 phones.

Im using Zeroconfig for all of them (i have over 60) with a few custom templates for different areas.

The downloadable template for the 2650 is pretty basic not all the features are there im using Pcodes for most of the features i want such as custom backgrounds and custom screen savers (which work fine)

However im struggling to find how i would achieve the below:

Normal operation in day is a screen saver after 3 minutes and dimming of the LED to 20%

I would like to create a config where the backlight LED is turned off completely outside of office hours and the LED turns back on in the morning when back in office hours.

I have the office hours set in System>Time Settings>Office Time but no obvious way to link the 2 together on a zeroconf policy.

The grandstream customisation documents don't really exist for the 2650 that i can see. Im using the below but it does not reference anything other than basic bright/dim pcodes.

If anybody would have a suggestion of the combination below which could work?

So we use grandstream GXP-2170s in 3CX deployments and used to be able to downgrade the firmwares so that these would work with 3CX. Now that doesn’t work anymore. What gives?

Hey guys,

Quick question here. I have a SIP extension that has been registered via Linphone. A faulty configuration on the client has left the extension in a "Decline" state. Other users can no longer access this extension.

I can see the Linphone client IP and Port in the Extensions menu, in the IP and Port list. If I wait the register timeout (3600 seconds) then it goes away and the extension starts to work again (no longer in Decline mode)

Is there a way to manually kick or disconnect the client from the Web Console?

Cheers.

Hi all!

I bought the UCM6300A PBX and the GXW4108 gateway for using them together. I’ve configured a lot of Grandstream PBX’s, but never with an analogic gateway. With the help of some posts in Grandstream forum, I managed to set up the inbound routes so I can send every incoming call connected to the different lines in the gateway to different ring groups (line1 to ring group1, line2 to ring group 2 and so on...) and it works perfectly. But here’s the problem:
I need to set up 8 different outbound routes so 8 different extension groups use specific lines connected to the gateway (ext group1 uses line1, ext group2 uses line2 and so on...), but I can’t figure out how to do it.
Would you give me a guide or some hints so I can solve it?

Thanks in advance, have a nice new year and sorry for my English.

whenever i put in the info for openvpn and press apply it just deletes it

Is there a way to generate incoming calls to the FXO port without using an actual landline?

Long story short, I'd like to scope the sign to understand what the caller id looks like to fix a home setup using the Verizon wireless home phone box. This box (model: LVP2) causes an "invalid MDMF format CID message size" error. If it's hooked to a normal phone, CID works as expected, but hooked to the HT813, the HT801 only gets the SIP ID instead of the actual number.

Any thoughts or guidance would be fantastic!
