I read the thread about a peer being unreachable. My situation is similar but did not really make out what the user did after all the posting.
Analog phone plugged in and works inbound/outbound
Ports 5060; 10000 & 20000 defined
grandstream phone with dynamic ip address
Read Asterisk, SIP and NAT at voip-info; setup accordingly
simple basic sip
Start Asterisk ----> CLI and receive the following
sip_poke_noanswer peer is unreachable.
SIP is enabled on vpn/firewall encryption
What gives? Any suggestions would be appreciated.
