Hello... is there a default timer on the UC520?
Conf calls users are complaining that the calls drop after 60 minutes. The provider checked their settings and suggests the problem is on the UC520.
What version of IOS is the customer running on the UC520? I do know that there are bugs in the IOS versions in the 4.2.0, 7.0.0 (early adopter), 7.0.1 (early adopter), 7.0.2, 7.0.3, 7.1.0 (early adopter), and 7.1.1 (early adopter). I have not tested the 7.1.3 release, and I am not aware of the bugs in that release. The Cisco TAC will not support any outdated early adopter releases. In addition, UC520 units that have been upgraded from a 4.2.x to a 7.x release might be misbehaving because it is incorrectly configured. If you have upgraded your UC520 unit from a 4.2.x release to a 7.x release, please send me the configuration. I will look over it to check for configuration errors that might cause problems in the 7.x releases.
Here are the 9 known officially supported IOS versions on the UC520:
Here are the IOS versions found in UC520 early adopter software packs:
Here is the only known officially supported IOS release on the UC540 (a new product):
I've just noticed the ios is 12.4(24)T with Cisco Unity Express 3.2.1. Does this create a discrepancy? Can I upgrade CUE to the latest version or will that create complications?
Yes, you can upgrade from CUE 3.2.1 to 7.0.3. However, you should use the CUE 7.0.3 release included in the 7.0.3, 7.0.4, or 7.1.3 software pack.
Here are the IOS and CUE versions in the 7.0.3 software pack for UC520:
Here are the IOS and CUE versions in the 7.0.4 software pack for UC520:
Here are the IOS and CUE versions in the 7.1.3 software pack (early adopter) for UC520:
John... thank you. I found this link also and am going through the info.
Sorry.. I'm not getting prompt enough cooperation and responses from the users to work on this issue. I'll have to put it on hold until they get back to me. Thanks for the input.
I set up a SIP call to a public station and let it stay up for an hour. I made three calls (one at a time) over the last 3 hours.
I did look suspiciously at the SIP TLS 60 minute timer, but I am not using TLS.
Nonetheless, I did see the following messages at exactly 1 hour. And the calls stayed up each time.
(My UC is behind an SA540, hence the .104 address for the UC540).
