Recently I switched to 2Talk for VoIP as I got a naked broadband at home. I followed the VoIP configuration guide on this forum to configuration the HG556a router. Initially the outbound and inbound calls working fine without any issue. However, after a few days the inbound calls not working, but the outbound calls still worked as expected. The thing is, if I make an outbound call, then the inbound call working again for a varied period, before stopped working again.
I tested the incoming calls on a softphone in my PC, and could receive incoming calls anytime. Seems the problem is on the Huawei HG556a.
Does anyone has the similar issue on the HG556a before? And how did you sort that out?
