Hi Daniel Thank you for your prompt response. I have the following entry in the dialplan list: Dpid = 1 Match Op = 1 Match Exp = sip:3020.* Match Len = 0 Subst Exp = sip:(3020)(.+)@ ReplExp = sip:3020A\2@xx.xx.xx.xx and i only want to allow the source ip yy.yy.yy.yy to use this specific dialplan and only this dialplan. I guess i need to combine the dialplan module and permissions module but im not sure how. As i have many entries in my dialplan list, would there be an easy way to achieve the above? Thanks again Phillip On Wed, Dec 8, 2010 at 12:30 AM, Daniel-Constantin Mierla <miconda(a)gmail.com
