You will get a lot more responses if you also subscribe to sipx-users mailing list. I come to the forum maybe once a month, but if you subscribe to the mailing list, your posts go there also. About the current state of trunking in sipx... ** Interoperable Internet Telephony Service Providers (ITSPs) Following are the minimal requirements for interoperability : Must support RFC 3261 Must support Re-INVITE (with and without SDP) for mid-call codec renegotiation. Must support Session Timer. Must support P-Asserted-Identity extension header to present correct caller ID during call forwarding and blind transfer operations and for anonymous calling. While SIP interoperability in general has made significant progress, it is still required to test interoperability with each and every ITSP to make sure all the required features for successful SIP trunking work. the following is the current list of ITSPs that we were able to test against. This list highly depends on the availability of suitable test accounts. Should your preferred provider be missing and you would like to get it added, please say so on the sipx-dev mailing list. If you can provide a test account together with your request, then that would increase the chances of getting help with resolving interoperability issues. CAVEAT : An entry in the table below does not guarantee that the ITSP is well behaved or of good quality. Careful testing has been performed on bandwidth.com, at&t, bt.com and cbeyond.net. An entry in the table indicates that somebody ( for example, member of the sipx user community ) has tried out the ITSP and has reported that it worked and has shared their settings. att.com bandwidth.com bt.com voxitas.com sipcall.ch: sipcall is an ITSP in Switzerland. DID numbers in Switzerland are free. CallWithUs: CallWithUs is an international VoIP provider offering SIP and IAX service Cbeyond: Cbeyond is focused on small business and provides dedicated T1 service.

Perhaps you can ask if they support the features NEEDED in order to comply with the trunking module, or perhaps find one that does? -- ===================== Tony Graziano, Manager Telephone: 434.984.8430 sip: mailto:[email protected] Fax: 434.984.8431 Email: mailto:[email protected] _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
