Dear Team,
I am facing an issue on my IP Telephony Network. When i make call to any PSTN number than I didn't hear the Dial toner until some one pick the call
and same issue to make Inbound call from PSTN. Any one call to my Network from PSTN didn't hear the dial toner until some one pick the Ph. We have
SIP trunk to Cisco Gateway.
Can any one sugest what are the possible causes for this kind of issue?
Thanks
Jehan
