This puzzle is still lurking for me. I have a sip DID
provider. My registration to the provider works fine. I haven’t opened up
externip and localnet in my sip.conf file but in my router forwarded ports
5060-5061 and 10000-20000 to my asterisk box.
When i dial my DID number it comes through fine and i can hear the
greeting with “please enter your password” message
but when i enter password number on my phone, the signal doesn’t reach my asterisk so the system waits and says “no passwrod entered”.
I can’t see a reason why this is happening.
My DID provider’s IP is for example 18.104.22.1689. I have only allowed
ports 5060-5061 and 10000-20000 for that IP in my firewall and router. My asterisk is 1.2.x (latest). My phone is a normal pstn cordless phone.
Any suggested will be received gratefully.
