Internal Extension Call Pickup && Dialplan Reload Error

Hi All

I has setup a new FREEPBX Distro 64 bit.  Configured TLS & SRTP settings.  I Created 2 Extensions.

501 & 502 - Both are registered

I Can call from 502 to 501. Both can pickup the call and TLS & SRTP works with Voice well.

From 501 to 502 its ringing, i couldn’t pick the call. Still shows ringing.

Codecs are fine with the Blink Softphone.

Can you help me with this to fix.
