Is it possible to use HT813 ATA without PBX?


#1

Hi!

I don’t know a lot about IP telephony but I know a few.

I use some grandstream ip phones in my office and work great.

Now, I want to use my standard analog phone line in my home with an IP phone, without any PBX.

Can I connect my standard analog phone line to the FXO port of the HT813 and then create a SIP account to my IP phone to connect to the HT813 to make and receive calls through the FXO port?


#2

Yes.
It is not easy to do, so if you lack knowledge i suggest ask pro (well i think it is easy but was reprimanded that it is not easy).


#3

Thank you Marcin,

I will be back for a feedback after complete the installation


#4

Hints:
Remember to set correctly PSTN (can be challenging)
In general it is not much different then Ht-503 so follow their manual:


#5

Hi kkkk: was you able to connect sip software to HT803 and make PSNT calls witout PBX?
Can you explain how, please?

Hi!

I have just installed the HT813. I received it an hour ago.

Now, I can make outgoing calls using an analog phone connected to FXS port and the PSTN line connected to FXO port.

I haven’t succeded to make outgoing calls from my IP phone.

I will try it and I wil be back for feedback.

Hi Marcin,

I set FXO Port in the same way as on HT503.

I cannot register as this SIP user on my IP phone.

Do you have anything to suggest?


#10

You do not register, uncheck register.
It is IP-IP connection only.
In phone: add server as HT IP:port (usually port is 5062 - you can find it in FXO page) and gateway set up same as for other gateway (there is no difference here at all if end point is phone or gateway).


#11

Sorry for asking again.

I setup FXO port of HT813 with an IP at 5062 port.

Also, I setup a SIP account on HT813, without any registration required.

Then, I setup DP720/DP750 with a new profile for the IP of the HT813.
What have to set on DP750 as SIP Account Settings to access the FXO port of the HT813?


#12

SIp Server as HT+port
Turn off register.


#13

These are the screens from HT813 and DP750 admin page.

Is it possible to find out the problem?


#14

Where is port in DP ?
192.168.0.23:5062

Also DP profile 3 is not on 5060 so you need modify server in HT for correct port (also forward).


#15

ok. I fixed the ports.

Now, when I make a call from DP it rings the phone that is connected to FXS of HT.

Also, when I call at 8888 (the SIP of FXO) also happens the same, the phone at FXS rings.

Anything to help?

How can I access the PSTN line connected to FXO ?


#16

Ring: wrong port. Check FXS and FXO port, they should be different. Put FXO port to DP.

Did you set forward on Basic page (HT) to DP ?
Also you can turn of this FXS ring in HT on FXO page.


#17

It is a little bit confusing!

Anyway, the fxo socket on HT goes to PSTN. The fxs socket of HT goes to an analog phone. So, no problem from here.

I can’t find a solution right now. I will continue this task in a few hours.

Thank you very much for your support.

In addition to what Marcin indicates -

I may be a little behind as I am looking at the pix you posted, but why is the SIP server setting for the IP in the HT and the DP the same? I assume you want the HT to point to the IP of the DP and the DP to point to the HT.


#19

Thank you Ipneblett for mentioning that.

I haven’t finished the installation, but I can make outgoing calls from any IP phone through the FXO (PSTN) of HT (in addition of making outgoing calls with any analog phone connected to FXS of HT).

I have a lot of things to check.
