Dear All,
I am having problem on my branch office with hold/resume. Here is my call flow;
Cell Phone -> Analog Line -> FXO Port -> VG -> H.323 -> CUCM
When an external phone user calls my branch office over Analog line, it goes to DN on CUCM succesfully. When IP phone user holds the calling side on the line it is able to listen MOH after that when IP phone user presses resume calls continue for a few seconds (sometimes 2 secs sometimes 15 secs) then suddenly it fails.
Here is voice port config;
voice-port 0/1/3
trunk-group PSTN
supervisory disconnect anytone
timeouts interdigit 3
connection plar XXXX
description XXXXXXXXXXXX
caller-id enable
I am attaching debugs so anyone can help me?
Thanks in advance

What router platform and IOS version are you running? Also can you provide the debugs again, but turn the debugs on just after the internal user answers the call then get them to hold then resume the call. Thanks

Hello Heathrw,
I think I have solved the problem by adding below configuration;
voice-port x/x/x
supervisory disconnect dualtone mid-call
supervisory custom-cptone XXXX
supervisory dualtone-detect-params 1
timeouts interdigit 5
timeouts call-disconnect 5
timeouts wait-release 5
timing hookflash-out 50
timing guard-out 1000
!
voice class dualtone-detect-params 1
freq-max-deviation 25
freq-max-power 0
freq-min-power 13
freq-power-twist 4
cadence-variation 4
!
voice class custom-cptone XXXX
dualtone disconnect
frequency 450
cadence 200 200 200 200 200 200 600 200
now everything works properly, I am monitoring.
