Make sure you have nat=yes for the sip.conf entry for SIPGATE.     ---------------------------------------- Michael Shuler, C.E.O. BitWise Systems, Inc. 1301 W.

Somehow it is working. The connection works. Everything seems to be fine. I could talk to the external phone. But: the external voice gets not transmitted to my internal (calling) phone.   Calling inbound from SipGate to the same phone works perfectly. Both channels are perfectly “proxied”.   The * is used as a proxy and registered the sipgate account.   This way works:   SIPGATE ---àNAT(IP0)----àAsterisk(IP1)-----àIP-Phone(IP2)   This not (partially):   SIPGATEß--NAT(IP0)ß---Asterisk(IP1)ß---IP-Phone(IP2)   All ports are mapped to the address of IP1. If I look into the tcpdump log it seems that all ports used there are matching my NAT settings. Asterisk is happy. No problems. I only run into immediate abortion of the call if Asterisk is configured using outbound_address with the ip of IP0.   I have no clue what to do anymore…   Regards, Markus   ____________ Virus checked by G DATA AntiVirusKit Version: AVK 14.0.635 from 31.03.2004 Virus news: www.antiviruslab.com
