thanks for your comment, how to fix this problem?You have auth-calls enabled on your profile, which is good but the phone doesn't authenticate the call so it fails i guess..
Grandstream 2160, 2170, MicroSip, and PortsipWhich phones are you using?
internal or external ?Which profile are you hitting, can you show the configuration of the sip profile?
Depends on which profile you're sending the call, it would be the one listening on 5060 port, i guess that should be the internal profile by default?internal or external ?
thanks for ur help, now I repair my internal profiles and some calls are ok and some calls are not ok, when call is ok but no sound? so what is the problem?Depends on which profile you're sending the call, it would be the one listening on 5060 port, i guess that should be the internal profile by default?
