I have a solution for 3 way calls which should meet my occasional need for the functionality.

I think that's as good as you can hope for / expect. I don't think VOIP is particularly remunerative for AA (or anyone really in this particular part of the market) - probably therefore not very high on their list of priorities. But you never know.

I needed to use a 3 way call to speak with my parents and insurance provider.

Using SessionTalk and AA, which had been proven to work for 3 way calls, I called the insurance provider, went through the menu system, 1,2,2,1 and then got a continuous tone instead of speaking to the correct department. Repeated a few times. Used my EE mobile and OK to speak to someone.

I worked around with a 3 PAYG SIM in another phone.

I've just tested with Acrobits/AA and same issue. However, Acrobits/SIPgate was fine.

I haven't done a wireshark trace or informed AA because I'll just be informed that "NAT is evil". However, SIPgate is fine with NAT.

I suppose I could look at allowing my non-static BT FTTC IP (which I understand could change) through the firewall on a non BT router - to see if I have the same issues with AA.

I'll need to google to find a suitable guide so I don't end up with a security issue!

Yeah it’s not NAT (or the client) given this all works with Sipgate and Acrobits (same combo I’m using).

Points to something within the AA VoIP platform / specific to their implementation.

I don’t think messing around with your firewall settings or looking at traces from Wireshark will bear much fruit.

I reckon it’s squarely in AA’s court. Just a corner / oddball case.

Thanks Pheasant,

It looks like I'll need to keep my basic/free SIPgate "test" VoIP number for the foreseeable future because it is the only VoIP (with NAT) which can perform 3 way calls and connect to an insurance department following an interactive menu.

I'll probably use AA to port my BT PSTN when FTTP arrives.

I may look around for a low cost VoIP provider just in case SIPgate pull the free product.

I had planned to use the VoIP when roaming (with a data E-SIM), plus the the occasional 3 way call, and just to keep the PSTN number just in case someone didn't have our mobile numbers.
