[Asterisk-Users] ERROR: retrans_pkt: Maximum retries exceeded on call

[Joseph]

Can anybody provide any input on an error:
retrans_pkt: Maximum retries exceeded on call

My extension 11 will not ring.  I can dial out without any problem but
when I call in it goes straight to voicemail box.

Goto (office-open,s,1)
