I have issue with CUEAC ,i can answer an incoming call ,but as soon as i try and put the user on hold the call gets dropped ,any ideas ?
Please check if you have free CTI ports to hold these calls? Also check if theye are in registered state in CUCM.
Hope it helps.
Please rate helpful posts !!
Try Disabling the Advertise G.722 Codec Enterprise Parameter
Or force phones to talk on g711 with CTI ports ?
Is it happeneing for internal or external calls or both ?
If only external calls then what gateway MGCP or H323 / SIp
If h323 or SIP check the Dial-peer codec config etc .
I have G722 disabled ,i am also using the new Cisco Media driver ,so should be able to use G729 codec to CUEAC ,according to release notes ,using CUCM v 8.6. I am using H323 GW and dial-peer i have tried on G711 but same issue. So far it is only for external calls.
I would still suggest Under the region configuration, Change the codec used between the CTI
registered port and the phone from g729 to G.711 codec. and then check
When you put a call on hold, the system basically transfers the call from the attendant phone to a CTI Port.
Check the logs on the server for any errors arising when this happens. It might be a problem with the reachability (i.e. CSS/Partition) setup.
I've also seen problems where the CTI Ports were assigned MRGLs with multicast MoH enabled - if that's the case try removing any MoH devices from the MRGL and ensuring all MoH devices are assigned to at least one MRG (i.e. so any mcast MoH sources are not left in the default pool).
Can you provide me with the call manager traces for a test call so, that we can identify the exact issue?
