[asterisk-users] phones behind nat

[Jerry Geis]

I have a setup where I have polycom phones in an office, behind firewall,
going out to a server located elsewhere. I have set
nat=force_rport,comedia for my phones.

so if I call OUT to my cell I get audio both ways and the call is fine.

My issue is if I call phone to phone in the office the phone doesnt
even ring. The CLI shows I'm calling the correct extension like SIP/524.

I am using asterisk 11.19.0

Is there another setting to correctly to this type of calling?

Thanks,

Jerry
