Remote Extension Asterisk Grandstream GXP 2000
Posted on 2011-02-19
triyng to get Grandstream GXP 2000 to work externally with my asterisk system. Looking at IP tables logs I can see my IP coming into the system on port 5060. My grandstream shows detected NAT type is port restricted cone when I specify my stun server.
sip_nat_conf is as below:
Asterisk NOW version 1.7.1 and Grandstream is on latest firmware. To note I have had this extension working as a remote extension with 3CX with no issues so my firwall at home is ok.
