Conf issue

[user-cisco]

hi

i have a problem with meet me conference like this:

a user initiates a meet me conference, and when a PSTN (landline) caller calls the meet me number he joins the conference without any problem, the issue is that when a caller calls the meet me no. from his mobile he gets a busy tone and cannot join the conference the same things happens when an internatioanl caller calls the meet me no. he encounters the same problem as well.

did any one happen to have the same issue or solved it?

please advise

thanks

if you're using the SW CFB for this verify the call legs for the mobile and international calls are made using G711, if they're using G729 they won't connect because the SW CFB only supports G711
