Dear Mr. Jacob and the Sifira team chan_ss7 is a great project and it is progressing at a great pace. I am sure that soon it will catch-up PRI functionality available for asterisk. chan_ss7 is a great advantage to asterisk acceptance in the carrier world. We have been using chan_ss7 since its first launch of ver 0.3. And we are successfully using it in our production system with 4 E1 then and now we have added another 4 E1s making it all together 8 E1. We have around 4500 very cooperative registered SIP, IAX and OOH323 users and around 2500 concurrently connected users. Its running very very stable and I also patched the latest 0.8.3d patch as well. We have up to 242 users using chan_ss7 during peak hours. We have only one last issue that some time from PSTN end the ringing tone disappears. (May be some SS7 timers issues). Our system is a good reference for Sifira team please feel free if I can be of any help to test and try various options on our system Like we have to separate SS7 links on two boxes connected via IAX etc. etc. Looking forward for the release of 0.8.4 version :) Cheers. Michael Tan Telonix Singapore.
