You are looking for a phone number to make a PTCL test call to check your phone line similar to the Skype test call? There is as such no PTCL test call system available however, there is a free solution to verify your phone line. Just call 1236 (call made to 1236 are free) and talk to the PTCL representative (live human being) if they can listen to you and you can listen to them it mean your phone line is OK. In this way you can verify your phone connection for free. It will be nice if at some stage PTCL launch a automatic PTCL test call system to test a hand set, phone line connection and its installation just like Skype test call.
