Hi I have a problem registering a gateway, the return error is DNS error [503]. My DNS is OK, i can dig to the destination domain in question, and even when o do sofia_dig in fresswith it resolves the domain without problems. how does freeswitch resolves the destination domain? if you need more information, please let me know. Btw i just compile the last git head. Thanks, António ******** Log register. 2012-01-25 17:20:42.637192 [NOTICE] sofia_reg.c:414 Registering sol 2012-01-25 17:20:42.737189 [ERR] sofia_reg.c:2004 sol Registration Failed with status DNS Error [503]. failure #1 2012-01-25 17:20:43.637195 [WARNING] sofia_reg.c:473 sol Failed Registration [0], setting retry to 30 seconds. ******** sofia status gateway sol: freeswitch@internal> sofia status gateway sol ================================================================================================= Name sol Profile 192.168.10.25 Scheme Digest Realm mobile.commsmundi.com:5060 Username 2203 Password yes From <sip:2203@mobile.commsmundi.com:5060;transport=udp> Contact <sip:gw+sol@192.168.10.25:5060;transport=udp;gw=sol> Exten 2203 To sip:2203@mobile.commsmundi.com:5060 Proxy sip:mobile.commsmundi.com:5060 Context incoming Expires 1800 Freq 1800 Ping 1327508466 PingFreq 25 PingState -1/0/1 State FAIL_WAIT Status DOWN CallsIN 0 CallsOUT 0 FailedCallsIN 0 FailedCallsOUT 0 ================================================================================================= ******** sofia_dig: freeswitch@internal> sofia_dig mobile.commsmundi.com Preference Weight Transport Port Address ================================================================================ 1 0.200 udp 5060 192.168.10.1
