As mentioned in a previous post, our 827 is dropping call after ten minutes. After some debug, it appears that the gateway is registering as a gateway and then a couple of minutes later - unable to register.... This happens about 3-4 over a ten minute period, then my call is dropped. I'm including the debug I collected.
During the times when the gateway can not register, Ican not make calls, but my established calls remain. I'm using the latest version of code (12.2(8)T4) As stated previoulsy I have by-passed the PABX and have found the same results.
Now that we know your gateway to gatekeeper registration fails we can troubleshoot further. The reason ofcourse that you cannot make new calls is because we cannot place the RAS signaling. The reason your established calls remain is because after RAS signaling which has already taken place for them, the RTP stream passes between the gateways and the gatekeeper registration becomes secondary.
You need to debug h225 asn1 & debug ras on the gateway, and see whether the RRQ that we send is received and whether you are missing an RCF (registration confirmed) from the gatekeeper. If you miss up to 3 registrations, that means you send up to 3 RRQs without an RCF (after the gatekeeper registers we still do this because it acts like a keepalive) then we lose connection and try to establish communication again.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
