VXML RINGTONE SERVICE Problem - Call is not routed to agents

Question

We got below mentioned error in CVP Call Server logs for our calls. Due to this calls are not routed to agents.
Apart from our call flow, I need to know what is the cause and solution of this error.
Aborting XFER and disconnecting the caller code 488. RINGTONE SERVICE is not answering within 5000 millisecs, or the caller did not receive or accept the reinvite for ringtone media setup.

Answer 1

Hi,
//After that the agent goes to Reserved state but the call doesn't come through.//
 I don't have experience on PCCE , but UCCE perspective this looks to me more like ATR(Agent Targeting rule) or Device Target Issue. Ringtone service should not cause Calls to fail.
Can you please post log from CVP, for Particular call that faced this issue?
Regards
