Hello I’m using Asterisk 1.8 VOIP Sip, I’m having Problems at customers with Router N600 VDSL, that after 4-5 minutes during a call, Customer (that has the router) stops hearing his clients.
I check all over the interent and talked with DSL provider who supply the router (who has no idea was can be problem).
SIP ALG is disabled, And netgear is simple router (not like fortinet) so i dont undestand from where issue can come
Is anynoe experienced it ? Or know about this problem?
Please help
thx
