Thanks for your qucik reply. I am unable to change my SIP URI to my pennytel a/c, whenever i input my code after receving call from Voxalot the system msg. comes: your pin no. is not correct. I have tried to do it thorugh Xlite, Eyebeam and SJ softwares and always getting the same msg. My pennytel SIP URI is:
88807770@incoming.pennytel.com
