Hi,
I have been using VoIP in Pakistan since January 2005 - and NEVER experienced any problems. Whatever is suggested here about PTCL blocking 5060 port, etc. - is a nonsense. All internet traffic ultimately goes via PTCL as they control Pakistan's ONLY internet gateway in Karachi...
I SUCCESSFULLY used the following providers:
- voipfone (my favorite - for their rates, SMS callback and forwarding)
- babble (my second favorite - for voice quality)
- sipgate.co.uk (favorite for a free UK *local* number but not for rates)
- stanaphone
- sipphone (love their daily free 5 minutes)
- voiptalk
I don't want to advertise any of them - I later found a couple of *much cheaper* while equally reliable SIP providers. Just wanted to say you have to fiddle around with the configuration of your soft-/hardware and not blame PCTL or whoever.
I used SNOM 190, loved the sound quality and 7 lines but can easily imagine a less buggy firmware...
Forgot to add: my IP was Micronet (Islamabad).
Regards,
Kacper |
