So I use Linksys PAP2T VOIP Adapter for VOIP calls. Starting this month, Im noticing the VOIP adapter's LINK going down now and then. And I have to reset my modem to get back the LINK.

This is mainly for my mom who uses the VOIP phone to make calls to my sis in Singapore. Each time the link goes down, she'll complain that shes not able to make calls. And i have to reset the modem.



Also people have reported of Airtel blocking the VOIP traffic.



Any one with similar issues ?
