Audio lost when calling tropo through SipSorcery

Hi,

I tried the recipe https://www.sipsorcery.com/mainsite/Help/TropoCallback and it all seems to be working properly except that I cannot hear any audio. I do receive it when I call the original @sip.tropo.com address but it gets lost when I call the @sipsorcery account and enter the @sip.tropo.com account as destination in my dialplan.

One thing you could try is leave any private IP addresses alone when you forward the call to Tropo.

Change

Code: Select all

sys.Dial("99914xxxxx@sip.tropo.com")
to

Code: Select all

sys.Dial("99914xxxxx@sip.tropo.com[ma=false]")
This may not make any difference in which case the other thing worth quickly trying is to reboot your router on the off chance it has some stale NAT entries that are preventing the RTP connections from being correctly forwarded.

After those two options it gets a lot harder to narrow down the cause. What sort of internet connection do you have? if it's a mobile connection there can often be dual layers of NAT which play havoc with SIP and similar protocols.
