I had a similar challenge a while back and I solved it with asterisk running as a vm. I tried terminating the sip trunk on an mgcp router and was only getting signalling passing. I then moved the router to h323 and had one way issues. I realised having spoken to cisco that I need to get cube license for each anticipated b2bua call. A little more experimenting and I came up with a plan to move the sip trunk direct to Call manager. CUCM cant do user agent based sip trunks however as they only allow ip based sip trunks. This is how asterisks came in to the picture as now it have trunks set to my itsp from asterisk and then from asterisk to CUCM . Two years and counting and this solution has been working without skipping a beat. On Fri, Aug 13, 2010 at 6:13 AM, Jason L. Nesheim <jnesheim at cytek.biz>wrote:
Cisco 2800, 3800, 2900, 3900, 2431/2432, 2435, AS53/4xx series, 7200, ASR 100x, are the ones that come to mind. On the non-IOS XE systems, CUBE worked in 12.4(22) and above acceptably well, but it's much better with 15.1T (specifically 15.1.2T where transcoding on SIP to SIP is supported using PVDMs).

I'm curious: which specific devices and IOSs allow hairpinning of VoIP calls?
