I have a problem that makes no sense. I have a UC520 that was installed earlier this week and the voicemail to email notification to email is not working. I am using my ISP's SMTP server for the Voicemail notification for the UC520 to send out the notification message. The server requires no username or password. I set up my PC to send email using this server and it works fine. When the ASA tries to get create the connection for the uc520 i get this in the log on the asa
Teardown TCP connection 230 for outside:18.104.22.168/25 to inside:10.1.10.1/46312 duration 0:00:30 bytes 0 SYN Timeout
why in the world would the ASA allow smtp traffic out the smtp server from a PC so easily but fubar the connection from the uc520?
here is what the network looks like
ASA - DMZ
192.168.0.0 INSIDE network
10.1.10.1 Callmanager/Unity Express
any input is appreciated Thanks a ton!
