thanks for reply.

nope, only calls the last registered device, if I power off and try all is well with all VOIP registered devices, even tried SoftPhone!

Simple

Gigaset n530 (newest version) (which replaces the n510 and n300s)

up to 8 dect handsets - 8 sip providers - 8 simutanious calls

and ebay the grandstream and possibly the yealink.


By saying no to dect you have made things complicated in an uneeded way

having a voip dect base station makes more sense than "voip phone" if you want to go that way use a mobile with a sip clinet.

this maybe the way forward, just didn't want to use DECT

Hi,

AAISP do ring all registered devices.

Can you confirm whether any of the devices are behind NAT? If they are then what configuration have you created such that AAISP can actually contact all VoIP devices rather than just the last one that created a mapping in your router?

Yes all devices are behind NAT, no configuration has been performed.

Why does AAISP state only the last registered device will be ring ?

and this has been confirmed now by three other techies on another tech forum.

Do you have this working on your VOIP with AAISP ?

AAISP stated to me in the logs, all devices were tried, but the first registered device didn't answer, only the last as per AAISP configuration panel.

Is this a NAT issue ? I'd be interested what is required to fix this. But surprised if I'm missing info on AAISP to fix this NAT issue, because it will be so common place.

So 4 VOIP devices configured identically, plugged into the same LAN and powered up at the same time but only the last one powered up rings for incoming calls? do they all work for outgoing calls? does it work if you plug them in to different LANs (e.g. take one and plug it in to a friend or families LAN who doesn't have a VOIP services).

Correct, only the last registered device as per AAISP -- Control Panel states this.

All work for outgoing calls.

and it's the same again if I take them anywhere, any LAN, last registered device rings - as per AAISP control panel - which sort of negates the NAT configuration thing ?

Again these observations are confirmed by 3 other VOIP users with AAISP, they threw in the towel and went with a VOIP base station and DECT or their own PBX !

Would have been nice if AAISP had given you a definitive answer to this scenario as it must be either possible or not.

Hi,

Yes, I have had multiple VoIP devices registered with AAISP and they all ring when the number is called. They have all been on separate IP addresses though, some might have been through NAT but not more than one via the same NAT gateway.

I strongly suspect that this is a NAT issue.

When you look at the AAISP VoIP config pages, what are the ports / IP addresses listed for the registered devices?

Is there any way to show how your router is maintaining the mapping between the internal port / IP address and the external port / IP address for each of your VoIP devices? Does your router have a VoIP ALG, is it enabled and if so exactly what functions does it do?

NAT and VoIP generally do not play nicely together and I can see ways that multiple VoIP devices on your side could each overwrite the NAT mapping in your router leaving only the last registered device properly connected.

PS: I assume you have read https://support.aa.net.uk/VoIP_NAT - particularly the part about having separate port configurations on the multiple phone?

It is very contradictory as stated

1. Wiki states all devices will be rung
2. Control panel Only last device is rung
3. Works but not supported

4. Support suggests creating a new telephone number and use that as a ring other number.

So two phones would then ring, but this is technically using two numbers and a forward!

Again other's tested have said this does not work, I've been testing this on and off for 2 years!

did you read the post, about four devices being used at different locations (IP). and only the lasty registered device rings.

"NAT and VoIP generally do not play nicely together and I can see ways that multiple VoIP devices on your side could each overwrite the NAT mapping in your router leaving only the last registered device properly connected."

does this not negate NAT, as four seperate IPs will all register as a single mapping in the router?
