How is your asterisk server connected to the PSTN? SIP/IAX out...ISDN/T1 out? Etc...
Are you looking for lost RTP between * and internal phones or * and external provider? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brent Davidson Sent: October 24, 2008 5:55 PM To: Asterisk Users List Subject: [asterisk-users] Sporadic One Way Audio I'm having an unusual problem at one of my branch offices. Every now and then they will make a call and the person they call is unable to hear them, but they are able to hear the person. The Asterisk server has only one ethernet interface and is on the same physical network as the 2 snom 300 phones and is connected to the PSTN lines with a Rhino R4FXO-EC card. Usually hanging up and calling back solves the problem, but it is still aggravating to the customer that has been called. Normally I'd suspect that something was only passing packets in one direction, but there is no firewall between the asterisk server and the phones and no iptables or anything like that running on the Asterisk server and sifting through sip debug logs to try to find one call out of maybe 50 has so far proven fruitless. Are there any common issues that might cause this?
