I am in the process of installing a 2821 router fitted with an EVM-FXS/DID card to replace an old PABX. Intermittently when the router loads the analogue phones do not work at all not even getting dial tone, However after restarting the router a few times they start to work as expected.
I initally suspected a faulty EVM-HD-8FXS card however after fitting a brand new spare I still have the same issue.
Even when the phones are not working the router can see the card installed but it does not see any hook switch activity (using the Show voice-port summary command)
I am happy its not a cable fault as this has also been replaced.
If anyone has any ideas what next to check next they would be appreciated.
In 2821 (as well as 2851) EVM-HD goes only in slot 2 not slot 1. Slot 1 is for other NMs not EVM-HD. Please make sure the card is slot 2. What is the IOS ver? Are u able to share config and some debugs?
