Call Flow : CVP comprehensive
ICM : 8.5.4
CVP: 8.5.1
CUCM : 8.5.1
Issue:
post IVR treatment, call is not getting transferred to agent extension. Agent is reserved in CTI screen but call is not transferred to agent extension.
Steps Tried:
- Tried with Agent target rule and static route
- deleted and created static route in CVP ops console
- Routed it from CVP to Gateway and Gateway to CUCM
- removed all CSS and partition
- Tried with different extension
NOTE: The issue is only when we dial from PSTN. If we dial route pattern from other extension, the call is getting routed to agent after IVR treatment.
Analysis:
From CVP, the static route is getting matched and an INVITE is sent to CUCM.
