I am having some trouble with an intermittent delayed dialtone on analog stations. I can usually figure out these types of issues, but I have gotten stuck. Any help or ideas is greatly appreciated.
[ul]
[li]Software Version: R018x.01.0.890[/li]
[li]Two different G350 gateways (both FW Version/HW Vintage: 30.27.1 /1)[/li]
[li]Two different MM711 modules (both HW Vintage: 33 - FW Vintage: 104)[/li]
[li]G350 Analog (on-board) ports (HW Vintage 0 - FW Vintage 73)[/li]
[/ul]
Intermittently, when going off hook on an analog station dial tone is not heard for some time. I can hear several "CPC" (open loop disconnect or voltage drop) sounds in between a few seconds before finally getting dialtone and being able to place a call. This seems to occur the first time you go off hook after being on-hook for some time and then will reoccur after several times of going off and on hook. There is no issue receiving calls. The station always rings and there is no delay when answering. I've tried multiple analog phones. The CM and gateway are on the same LAN with no network trouble between the two. There are no issues with DCP phones.
A 'list trace station' shows denial event 1644 when this occurs. In the below example, the trace was started at 09:53:20. The analog station went off hook at 09:53:22 and the denial event 1644 was displayed. Dialtone was not heard until the 'active station' event at 09:53:32. The station went on-hook at 09:53:41.
At first I thought I had a faulty G350 gateway as this was happening with two different MM711 modules and the analog ports built in to the G350. I swapped out the G350 and the issue persisted. I registered the G350 to another old CM (2.1) and the analog ports work fine. I think I have narrowed this down to either a translation issue or bug in CM 8.1.
I am a novice with these systems and might be missing something simple. Below is the configuration I think might be relevant relevant. I am looking for any ideas to try. Can anyone think of what I should try next?
