[Asterisk-Users] Brandwidth for making internet calls
My ADSL connection speed is 512Kb up and 128Kb down. When making calls from Asterisk to IAX and back to the Asterisk, the sound is choppy and 20% of voice messages was lost. What is the production bandwidth requirement per internet call. I understand there is no guarantee of QoS but at least a benchmark to follow. -- David Kwok Iaxtel/FWD # 17001813482 smime.p7s Description: S/MIME Cryptographic Signature

Two or three is about the limit if absolutely nothing else is burning bandwidth. As a reference point, a C7960 sip call across the same dsl circuit burns about ~80kb and provides a very good quality call. Iax calls (with gsm) uses considerably less bandwidth.
