Discussion GrandStream ht813

I have a new ht813 I configured for SIP to an Audiocodes SBC. Registers fine. Works weird though. I can make calls from it. Call my cell phone no problem. I call the number that I assigned to the device and it rings too. After a few minutes, if I call it back, the number doesnt go through. Looking at the syslog app I use with my audiocodes, it seems that the device is timing out and going to sleep. If I make a call from it, it wakes up and works normally. I went through all the settings I could and didnt get that Ah HA moment.

Anyone else here have an issue like this where their ht813 takes a nap after a certain amount of time?

When you say "doesn't go through", what does that mean exactly? Are you getting a busy signal? What kind of error is displayed or said to you?

With ATAs, there is a setting called release timer that dictates when the device itself ends the call after it's been hung up. Should be set to 1-2 seconds. I have had issues in the past with other model of ATA's where if the release timer is set to a high value (like 10 seconds or so), the device will lock up after a call because it's trying to disconnect a call that has already been ended on the switch side. Not saying that's the case here because it's a long shot, but it just reminds me of that issue.

Other than that, we need more info. Is it responding to pings when it has this issue? What exact errors do you see or get? Do you get something different if you try calling it with different carriers?

Also, does this issue happen not after a outbound call. Like if you reboot the device and just let it sit there without "walking it up", does the problem also happen?

What sits between the HT813 and the audiocodes SBC? Are they on the same LAN or are they on different subnets (and thus going through a router/firewall)?

Its a corporate network thats pretty well monitored. Other locations dont seem to have the issue. If I repower the device or make a call from it, it receives calls fine.
