Hi All

I was just wondering what the status of SIP-based voip (this is not skype for those who are wondering) is in Korea. Is anyone successfully running a voip ATAa or PBX / Gateway using a service like asterix or freeswitch by using a non-Korean DID? Does your ISP (eg QOOK) block you from using voip providers from outside Korea?

*edit* If anyone has had success in any form of Voip tunneling, I'd be interested in hearing about that too

Ok ... to put it another way, is anyone running Vonage successfully?

Probably not but there are no blockages, caps or throttles on your bandwidth so there is no reason not to (unless Vonage is doing IP checking/tracking and NOT allowing traffic to/from Korea as some US based services do).

Thanks for that.

I specifically had this (older) report in mind, although this might be only applicable to anyone in the US military using a Korean ISP:

To update on this issue (should anyone else encounter it in the future) I can confirm that SIP traffic will flow over KT's network without any problem (ie, without additional encryption).

I successfully tested a Polycom Soundstation IP335 phone with pfsense 2.0 RC3 and Freeswitch running on Ubuntu (amd64 package for Freeswitch is not working in pfsense at the moment). The SIP provider was Flowroute - they also provide a $0.25 credit for anyone wanting to test a voip setup.
