Asterisk <-> O2 Mobile <-> SIAX

[ObelX]

Hello @ all,

was anyone succcessfull running SIAX with Asterisk via an O² Germany UMTS connection?

As long as I use SIAX via WLAN all works fine. But when I try to log in via UMTS, I can't see anything in the Asterisk logfile. It seems that SIAX is not able to "jump over" the provider's firewall, but is there any outgoing firewall?

I use IAX2, the server port (5069) is reachable (forwarded to WAN).

Any ideas what to do?



Tnx, ObelX

Hello,

I know that t-mobile does block voip. However O2 should work without any trouble. Michael is our Asterisk expert, I will tell him to contact you.
