I guess you are wrong here correct one is 0=master 1=slave

If you connect to PSTN the you should user span=1,1,0

Hi

The timing source is the clock of the system. When a equipment is 0, the other should be 1. The correct is: 0=slave, 1=master. The default for private systems is "slave".

Hi There,

We have very old asterisk 1.2 running in production and it has following setting in /etc/zaptel.conf. I have read on web about span and they told span= <span num> ,<timing source>,<line build out (LBO)>,<framing>,<coding>[,yellow]

Just wondering why it has timing source 0 ? 0=master, 1=slave right ? Do you think i should change it to 1 ?

#Sangoma A102 port 1 [slot:2 bus:7 span:1] <wanpipe1>
span=1,0,0,esf,b8zs
bchan=1-23
dchan=24

#Sangoma A102 port 2 [slot:2 bus:7 span:2] <wanpipe2>
span=2,0,0,esf,b8zs
bchan=25-47
dchan=48
