3 Intrductin This applicatin nte describes hw t cnfigure Cisc Unified Cmmunicatins Manager Express (Cisc Unified CME) versin 9.1[Cisc Unified Brder Element (Cisc UBE), versin 9.1] fr cnnectivity t tw telecm SIP trunk prvider via the FrtisVx SBC. The deplyment mdel cvered in this applicatin nte is CPE t PSTN. This dcument des nt address 911 emergency utbund calls. Fr 911 feature service details cntact tw telecm, directly. Testing was perfrmed in accrdance t Cisc s SIP Trunk Test Plan and all features were verified. Key features verified are: CPE utbund t SP Offnet gateway(pstn) (G.711 is ffered first) SP Offnet gateway(pstn) inbund t CPE (G.711 ffered first) CPE t CPE (place call ut t the SP netwrk and back) (G.711 is ffered first) CPE Calling number privacy CPE Telephne Number Supprt digit translatins CPE Calling Name Delivery CPE Offnet Call Cnference CPE Intra-Site Call Cnference CPE Intra-Site Attended Call Transfer CPE Intra-Site Unattended Call Transfer CPE Intra-Site Blind Call Transfer CPE Call Hld and Resume (call hld is always dne n the IP PBX side) CPE Vice Mail CPE Find Me (CFU) Simultaneus Calls CPE Aut Attendant CPE Find Me (Call Frward On Busy) CPE Find Me (Call Frward Dn't Answer) PRACK with SDP (early-media cut-thrugh with DTMF (RFC2833) navigatin befre 200OK)) - call United Airlines The Cisc Unified CME/Cisc Unified Brder Element cnfiguratin detailed in this dcument is based n a lab envirnment with simple dial-plan cnfiguratins used t ensure prper interperability between TW Telecm SIP netwrk and Cisc Unified Cmmunicatins. The cnfiguratin described in this dcument details the imprtant cmmands that need t be enabled fr interperability t be successful and care must be taken, by the netwrk administratr deplying Cisc UBE, t ensure these cmmands are set per each dial-peer requiring interperating with the FrtisVx.

4 Netwrk Tplgy The netwrk tplgy includes the CUBE used in the Cisc Unified CME mde, cnnected t the FrtisVx SBC via a SIP trunk. tw telecm was used as the service prvider. Figure 1.

5 Features Features Supprted Call frm/t PSTN t/frm CPE Basic and Internatinal calls, digit translatins Call Hld/Resume Calling party number presentatin and restrictin Calling name presentatin DTMF Call transfers attended, unattended, blind Call Frwarding (CFU,CFB,CFNA) Supprt fr early media Fax using G.711 pass-thrugh Features Nt Supprted G729 cdec. T.38 fax relay. Page 5 f 24

6 Caveats CLID updates are nt bserved n call transfer scenaris. tw telecm desn t supprt G729 calls. Hence all calls were tested with G711ulaw. Scenaris that include Phne 3 at secnd PBX site were tested with the Phne 3 registered t a Cisc UCM and nt anther Cisc Unified CME. FrtisVx SBC des nt supprt/implement PRACK. Hence the Cisc Unified CME desn't send a PRACK. Early media was still verified. Page 6 f 24
