Hello, I have the following scenario * Freeswitch is behind NAT with external profile with ext_sip_ip and ext_rtp_ip * Echo from an external SIP provider test inbound works with audio * Calling outbound to the same external SIP provider works with audio * *Receiving a call from the external SIP provider and bridging it to another number at the same external SIP provider does not have audio* * Receiving a call from the external SIP provider and bridging it to a local Patton PRI works with audio I also set up another (modified NAT) profile * like external profile - but with a different ext_rtp_ip * calling outbound to via NAT profile to another SIP provider works with audio * *Receiving a call from the external SIP provider (external profile) and bridging it to another number ****at the another external SIP provider ***(nat***profile)** does not have audio* * Tcpdump btw. does not show an attempt of Freeswitch to issue any outbound RTP packet. I can see only SIP messages towards the outbound SIP provider* * So I think, there is a problem with briding a natted external call to another natted external call, both with ext-rtp-ip. It tried this on an older Freeswitch (1 year old) and with a more recent Freeswitch (1 month old), both behave the same. Same scenario with a non-natted Freeswitch works fine. Btw. Freeswitch logs do show RTCPpacket not written right after bridginbg the call. Question: Does anybody have a clue, what could cause the problem? Maybe there is any parameter in the profiles, that may help? -- With kind regards Peter Steinbach Telefaks Services GmbH mailto:lists (att) telefaks.de Internet: www.telefaks.de
