hi, i've a problem with My sip gateway's provider who use a communigate server.

 

when i call another phone who use the same provider and the called phone try to transfer call, my snomone receive a refer from communigate like this:

My provider can't change his configuration. How can modify snomone to resolve this problem. I don't want to allow tranfer on my trunk, or olny for one domain name like "fai.fr."

 

Best regards

No risk to be billed by my provider for bad redirection?

 

There is a risk. You must trust your provider, and you must also potentially trust the termination providers that he is using (REFER can be sent through them if they don't filter them out). There is a reason why this setting is "off" by default. usually you need it only for internal equipment. Originally we introduced it for Microsoft Speed Server that always wanted to refer the calls to another location.
