[Siphon] Using Local Asterisk Server with Siphon - Can't hear voice issue

[Tharindu Madushanka]

Hi,

I have compiled and installed Siphon into my Device and Simulator - 4.0 iOS. And used Asterisk server installed locally to test calls..

I could make calls from my device to simulator. it rings, but when I pick up either side can't hear any voice. Is there any setting I need to change in code.. ??

Please help me on this.

Thanks,

One way-audio is usually always associated with NAT issues. Make sure your extensions have nat=yes (or whatever the latest grammar is these days). Also, it'd help to have your SIP debugging on asterisk CLI while confirming the packets are being sent to the correct NAT'ed IP.

Hi,

I could hear the hold music, but can't hear the voice.. Following are few screen shots of my Asterisk logs and Siphon Settings.. I used both NAT on / off in Siphon settings (Switch).. But still with no luck..

Thanks for your reply..
