Ahsan,
1. IP phone quality would really depend on the VOIP connection you are using, if the phone has a codec etc in it then its a different ball game (you can use a ATA 186 for that) else its really your backbone which is the critical factor in this
2. most of PTCL’s normal bandwidth is compressed unless you take the VPOP or IPLC connection. with good compression and good gateways at both ends you are looking for a normal 12.8 per voice channel
3. I am in karachi so cannot answer your third question
hope this helps
Anwar
