Doesn't display the incoming call

Hi,

I am using asterisk pbx for my VOIP gateway along with one PSTN connection for incoming

device snom 320. Issue is that the incoming calls are not displaying the no. it’s displaying

as asterisk. Please help me.

How does the PSTN operator send the caller ID? How have you configured dahdi.conf to recognize caller ID signalling/

No As such there is no dhadi.conf and also i am using linksys spa 3212 device to connect my pstn line, is it possible divert the pstn call to voip extension.

Either you have explicitly overridden the caller ID somewhere, or you need to take this up with Linksys.
