Good day all. Have a customer with Valcom VIP-801A paging endpoints with 9620SIP station endpoints, configured in the session manager for connectivity. SIP Phantom phone used for paging - An ATA device is being used as a SIP endpoint at all locations. I checked the System Manager for managed endpoints and status of the station 67140 and it shows registered and active. Paging access is intermittently not working at all locations. Works properly most of the time. Will fail and then seemingly just reset itself after 30 minutes or so. Customer states that this didn't happen when they where on CM 6.3.8, but started when they upgraded to CM 7.0. CM list trace shows the following:
Denial Event:1220 Recovery on timer expiry Recovery on timer expiry.
See Cause Value 102 on page 56.
UID DIAG/LOC/CV
Cause value as defined in the Avaya denial table:
Cause Value 102
[0x66/0xE6] -
Recovery on timer Expiry
The equipment sending this Cause Value sent or received a Layer 3 Q.931 message. Sending
or receiving this message has initiated a Layer 3 timer that has expired. This Cause Value is
being generated in conjunction with Q.931 protocol error handling procedures.
This Cause Value has local significance only. The ISDN network between the user and the
equipment generating the Cause Value might:
• Send no cause indication through the network
• Send a more generic Cause Value through the network
Communication Manager logs timer expiry errors in the error log against the signaling group of
the D-channel where the error occurred. The signaling group (ISDN-SGR) error is Error Type 1
and the Aux Data contains the identifier of the Layer 3 timer that expired.
Communication Manager does not generate the diagnostic information for the Cause Value IE.
Any suggestions would be greatly appreciated as to why this keeps locking up.
