Symptom: Incoming external calls get a busy tone while the Cisco UMG is in normal operation with
CUCM.
CUCM.
Conditions: The scenario only applies in the following configuration:
•
E-SRST provisioning is enabled.
•
The CUCME-as-SRST dial-peer gateway is configured for H.323 or SIP only. If MGCP is

configured, then the workaround below is not required.
•
When provisioning ephone-dns or hunt groups only.
The busy tone is caused by the DN matching both the ephone-dn and the dial-peer. The ephone-dn is
configured with the default setting of huntstop and as a result, takes precedence over the dial-peer in
normal non-failover operation. This causes the call to get a fast busy since the huntstop setting stops the
router from matching any more ephone-dn’s and dial-peers.
