Remote Accessing ATA thru router

[roztom]

Assuming there is an issue having 2 devices registered at the same time. (X-Lite & ATA) ATA at home and X-Lite while traveling.

1. Is there a way to remote access the ATA through a router to disconnect it remotely so it doesn't register while using X-Lite?

I know you can remote access desktops and I assume you would be able to access the ATA but how could you cause it to "simply" stop registering.

This is only relevant if having 2 devices registered is a problem.

2. I use both devices together at times when I travel and my audio drops out on my X-Lite sometimes 5 min, other times 30min into a call. This is with good connection speeds and QOS. I suspect when the ATA re-registers it hits the same ports the X-lite is using grabbing the ports and causing the audio to drop. Is this correct?

Another possibility would be to have each device access through different ports. IS that feasible and would that work as a solution, assuming that is the cause of this issue?

THanks,

Tom

Tom,

You are able to have up to two registrations. Using your x-lite and ATA at the same time will not pose any problems.

However, two things may be possible that are causing your softphone conversations to eventually drop.

One is like you stated. There may be a port conflict between the two devices trying to communicate on the same ports. The adapter is configured to register ports 5060 or 5061, but the X-lite can be configured on a port range so it will grab any available port. You can set this up in the topology tab of your x-lite. I would recommend ports 5060-5161.

If you have this setup in the x-lite and are still experiencing the dropped calls then that would point towards a port forwarding problem. In most cases your router will need to be configured correctly if you're needing x-lite to have a consistent connection. The ports you'll need to forward are 5060-5161 (UDP) & 16,384-16,482 (UDP).

I hope this information helps, please let me know if you have any additional questions or should require any assistance.

Thanks,

Allen

Allen: Thnaks.. I have the ports set right on my X-Lite.

1. If I understand correctly even if both devices are registered at the same time, the fact they are using the same ports in not a conflict. Is that correct?

2. As far as the router goes, when I am at a remote location, I am sure their routers ports are not forwarded. Other than opening the ports, is there any way to work around this so the X-Lite doesn't drop out, since most routers are "tighter than a clams... in a hurricane' and won't be opened.

What do users do when traveling?

Thanks,

Tom

Tom,

1. Both devices registered on the same port would be a conflict, but if you have a range forwarded then a conflict should not happen.

2. Through my experience with the softphone at another location the call quality was sufficient enough for any phone call I made. However, the duration of my calls were not exceeding at most 15 minutes. Because the service is provided through an internet source, there's generally not much that can be done to optimize or fine tune the connection. I have had some customers who could not get a sufficient connection at a hotel contact the technical support for some temporary assistance. Other than that, in most cases your connection should be fair enough for any phone calls you'd like to make, assuming the bandwidth is enough.

Please let me know if you have any questions or anything else I can help clear up with you.

Thanks,

Allen

Allen: I'm curious why we can make a call on a non-forwarded router and then the call is dropped after 10 -20 min or so.

Does it have to do with re-registering or some other issue that causes the router to drop the call?

Is there an adjustment in the X-Lite that might keep it from doing whatever it does that causes the router to block the call after it's been established?

Thanks,

Tom,

It's a very difficult situation and honestly I don't have the most technical answer. Some of it has to do with re-registering the account, and also has to do with port sessions. They only remain open for a period of time before the session is closed and a conversation is dropped completely. If our service continues to look for the right ports then when a session ends it will terminate a call.

In the x-lite you can try upping your registration time, by default we set our ATA's to register every 3600 seconds or every hour. You can find this option in the 'advanced' tab on your x-lite.

I hope this information helps. I'm sorry I don't have the most concrete answer for you, but please let me know if you have any additional questions or comments.

Thanks,

Allen

THnaks: X-Lite is set to reregister 3600 seconds also. Are you suggesting to up it from there?

What is interesting about the port issue is that the router will let the ports be accessed and then after several minutes or so slams the door...

What does this say for router security or is that just becuase it is an internal access vs external.

For me, at least, I just don't get why it justs drops the audio/connection out once it is already established. But, hey... for me a little knowledge is a scary thing.. :)

THanks,

Tom
