First post so I’m not sure if there is where this belongs but…
Here are the simptoms.
Outside to IVR = OK, Extension to Extension = OK, Outside to Extension = Ring/no audio, Extension to Outisde, no trunks available
I am using freePBX’s installer package with both softphones and cisco sip phones,
we are using SIPStation for our SIP Trunking.
SIP Station says everything is OK,
Astrisk log is as follows:
WARNING chan_sip.c: sip_xmit of 0x8a277a0 (len 844) to 0.0.3.253:5060 returned -1: Invalid argument
there is a static NAT setup, and it was working,
phones are local subnet.
