For quite some time , there has been no problem (for me) with making two-way calls with Voxalot callback, eg using say Voipcheap for both call legs
The accounts do not accept many peering calls, for reasons I don't know about. Maybe it's firewall or port number issues, or just their policy, but I'm not techie enough yet to know.
If you have a DID pointed at an account, then there is some variation of behaviour. Pstn-sourced calls always get through via a free DID from 3 providers I've tried. SIP calls to these numbers can be blocked, even if called from another Betamax account, though an IPKall DID seems to be ok any time so far.
I haven't managed to forward a Sipbroker account to Betamax, but that could be my incompetence, or it doesn't work; let's hope for other comments.
