Hi!
I have a Grandstream GXP2000 cabled in using unsecured UPD and CSipSimple on my Android cell phone using TLS/TCP. Both extensions can make make and receive calls fine and the cell can call the Grandstream extension but the Grandstream can’t initiate a connection to the cell.
When I dial the cell’s extension the display on the Grandstream says:
Call Failled
Reason Code:503
At the CLI I get:
Everyone is busy/congested at this time.
I did get the No SRTP module loaded error on the CLI so I reinstalled after installing libsrtp0-dev and that error is quiet now.
The extension to the cell looks like:
exten => 111,1,Set(CHANNEL(secure_bridge_signalling)=1)
same => n,Set(CHANNEL(secure_bridge_media)=1)
same => n,Dial(${KEV_CELL_TLS})
I’m new at this and I just reinstalled Asterisk for some other problems. I’m quite sure this was working before I did the reinstall but I can’t really say for certain - too many experiments and lessons. Any tips will be appreciated.
Thanks!
Kev
