Hi all, I have a client that is having problems with phantom calls. I have not been able to see it happen myself, but they say when it happens, the display on the phone (polycom 301's) says "Device" is calling, but when they answer the phone, there is only silence and then they hang back up and it sometimes rings again. I've been trying to track this down for a couple of weeks now with no success yet. If anyone can lend a suggestion or a pointer to look for, I would greatly appreciate it. I've tried using WaitForRing() in case it is bad signaling coming from the phone company. But that has not helped. This setup has: Asterisk 1.2.17 Zaptel (whatever was distributed same time as Asterisk 1.2.17) CentOS 4.4 Polycom 301's throughout Sangoma A200 with 2 ports connected to PSTN. Thanks for any help. -- Warm Regards, Lee

But that has not helped.I highly doubt this is the cause. I suspect a dialplan error. Ask your client if they are doing anything else when this happens, like making a fax call ;)> This setup has: > > Asterisk 1.2.17 > Zaptel (whatever was distributed same time as Asterisk 1.2.17) > CentOS 4.4 > Polycom 301's throughout > Sangoma A200 with 2 ports connected to PSTN. > > Thanks for any help.We kinda need to see your dialplan to provide any useful help. -Stephen-
