Dear All!
We make a asterisk server ( Freepbx distro) in our Company.
We have Grandstream GXP 2124 phones.
The problem: When is pick up the handset, and say hello, nobody answer.
I can wait 1-2 second to bulid the line.
Internal and external calls, this is the case.
I do not know what could be the problem.
pls. help!
Thanks!
Enable the full log (logger.conf) and also enable millisecond timestamps on the log.
Issue:
core set verbose 5
core set debug 5
sip set dubug on
Make a call.
Look at the log. Are there any retransmissions? Do any responses to INVITEs get delayed? If so, which ones.
Possible problems: overloaded network; overloaded DNS server.
