3. The "tcp_port_range" value is the range of TCP ports beside the listen_port that Ekiga will use for the H.245 channel with the H.323 protocol. That port range is not used by SIP. It is also not used when H.245 Tunneling is enabled, which is generally the case, except when calling old H.323 implementations like Netmeeting.
4. "tcp_port_range" balioa erabiltzen du Ekiga-k listen_port-eko TCP ataken balio gisa, H.245 kanalerako eta H.323 protokoloarekin. SIPek ez du ataka-barruti hori erabiltzen. H.245 Tunneling-a gaituta dagoenean ere ez da erabiltzen; ia beti izango da hori, H.323 inplementazio zaharrei (Netmeeting-i, esate baterako) deitzen zaienean izan ezik.
