I have a remote client who is registering his x-lite with my Asterisk 1.2.23. the registration works just fine but he wont be able to receive ZAP call… Client is using a Sonicwall 2040 pro and I’m using PFsense so both the client and asterisk server are behind NAT.
I have 50 other users and it’s working just fine for them except this one client…
on my end, port 5060 and 10,000 to 20,000 are open… I asked the customer to also open port 5060, 5061, 10000 and 20000.
externip = my Asterisk ext ip
externip=my Asterisk ext ip
As I mentioned, I got other clients with the same configuration and works just fine…
how can I fix this? is there any setting that I’m missing in Sip.conf
Thanks for your help.
