Does anyone know and have experience with IAX2 phones?
I just ordered a few of these Yuxin YWH500D from:
I cannot recommend this retailer. I placed my order 3 days ago and I am still unsure if they are going to fill it. They have not responded over the past 3 days to email or phone calls.
I have found that the IAX softphone work flawless. We have had problem with SIP and firewalls. Basically, we have phones behind 1-2 routers both with NAT and SIP doesn’t seem work well.
