SIP TLS Transport Layer Security is used to encrypt SIP signaling between SIP endpoints. In order for this to function properly it is required that certain devices in the network import an SSL certificate. Before importing the certificate into a device such as an Acme Packet SBC it is important to know if the certificate is from a CA Certificate Authority or perhaps self generated in which case it would be considered a non CA certificate. Occasionally users have indicated the certificate is from a CA when in fact it is not. This may generate an error if importing a non CA certificate as a CA certificate. Below is a quick procedure to verify the certificate using Mac OS X or Linux. Cert. File. crtserver. OKIf the output is anything other than server. OK then the provided certificate is not from a valid Certificate Authority. For example openssl verify verbose Cert. File. crt. Call. Manager. Aug. 22. crt CNTESTCCMOUCISCOMCS7. OFPILMANILASTMAKATICPHerror 1. OKAnother alternative to verify a certificate is using Mac OS Xs Keychain Access application. Simply import the certificate and you will see something like this If using a CA based certificate here are the steps to generate a certificate request and load the certificate on the Acme Packet SBCPHOENIX configure terminal.

I am having a lot of trouble with Telnet sessions over the internet. After 2. 0 minutes of idle time the connection is often dropped. This is a major problem because of lost data entry productivity for many users. The users are at several locations with a PIX vpn to corporate. All are vpn over DSL. Previously this happened occasionally, now it happens very frequently. Now users at 3 of the 4 branch locations are dropping several times a day, it happens after 2. I have tried doing some diagnostics, testing, research, etc. Testing results Telnet connections are very reliable on a LAN or a decent point to point WAN such as fractional T1, idle time is not a problem, connections will stay for 2 hours at least. The internet connections are un predictable anywhere from 2. It is variable, some times the connection will drop 3 times in a row after 3. The testing was done over the internet with and without vpn involvement with no noticeable difference frequent and un predictable drops after 3. Pinging test with 1. Packet tracing did not show anything significant not to me anyway except after a certain amount of idle time a keystroke usually the letter c but anything causes the same result from the client causes a RST from the server. Then the client is disconnected from the session. I have duplicated these results consistently on several LANS using different DSL providers for both client and server, with and without vpns, using different Telnet client software and different server software. Any suggestions would be appreciated.
