Blink can now setup MSRP sessions that are encrypted end-to-end using OTR protocol.

It seems like our PSTN gateway provider went out of business and we were left holding the bag (GRN VoIP). We are working on finding another PSTN termination partner. The balances stored in SIP2SIP platform will remain unchanged, no money was lost.

I apologise for this and keep you posted.

News: September 4th: We have a new PSTN carrier now. Please provide feedback about quality.¶

SIP2SIP conference bridge now with OPUS codec and PSTN access number

http://wiki.sip2sip.info/projects/sip2sip/wiki/SipTesting

To increase the chance of connecting to the SIP server in adverse conditions imposed by the presence of SIP ALG enabled routers, we switched the default TLS port to 443.

If your SIP Client uses DNS for resolving sip2sip.info server addresses, there is no need to change anything on the client side.
