Hi Bilal,

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

make sure it is set to "False".

hi rob,

thank you for your response.

Did you mean /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tableau Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} 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.
