I can hear another Extension talking on my line


(Richard C) #1

Good Day,

I have a Un-common issue here, One of my customers (FreePBX 13.0.197.28). have an issue when they call out they can hear another Extention talking (only the Extension - no audio from remote Party.)

I have tested this. as below

I called from my 1001 extension to my mobile(0822222222). and i answered the call. I could then hear extension 212 talking but not the person they are talking to.

Please assist.

Is this an analogue DAHDI system, as only analogue lines would normally be vulnerable to far end cross-talk.

Hi no this is sip

Is the other extension on the same site as the complaining user? (If they are using ATAs, it could be cross talk on the analogue side of their ATA.)

SIP is handled purely as digital and something would have to be actively done to add voice samples from one channel to another, e.g. an explicit conference bridge or ChanSpy would need to be invoked.

Both 1001 and 212 is internal and running sip, no ata is used

Is there a chance the port was reused? i.e port constraint?
