[Asterisk-Users] Fast Start , Slow Start , or just Codec

[Voip Business]

Hello List

I am testing a new carrier  with h323 (for a special need) but  when I
dial to a pstn phone this is what happens:

both sides rings

Pstn line no audio when pickup

ip phone continue ringing.

I am using h323 (Not oh323)

the carrier says is a slow start and need fast start ,, how is it
done? or do you guys think is other thing.

thanks in advance ,


Humberto
