Dear Mr. Suvro,
*I agree with Palash bhai. For a guaranteed quality voice you should have
guaranteed end to end connectivity.*
Just to understand ur case if is there any other issue or not, can you
please share some information which would help to dig-out the issue:
1. Exactly what type of problem you face ( is it like delay of hearing,
distortion, breaking of voice etc. etc. pls specify)
2. Have you measured the loss, delay & Jitter during the time face the
issue
3. Can you share a call flow diagram
4. What kind of device/box you are using at your end? ( brand, model
etc...),
5. Does this box have Jitter buffering supported or not?
6. Can you pls take a capture of a call at the time you face those
issues and share with us
Thanks ....
*Apu*
