Re: fast busy tone after transferring externals calls

Hi Bilal,

Try this Service Parameter under CUCM "Block External-to-External Transfer"

make sure it is set to "False".

Re: fast busy tone after transferring externals calls

hi rob,

thank you for your response.

Did you mean Block OffNet To OffNet Transfer ?

if yes, this service is already set to "false"

In my environement, i have CCM 7.0 and 2 gatways h323 3825 and 2811 (all within same Vlan). the 2 gateways are configured the same way but the call transfer works fine with the 3825 gateway but it does not with the 2811 one.
