It may be a solution , but there are some problems: 1)i need a router with many PVDM for transcoding, instead if i use MTP with trusted relay point i can use router with software only MTP 2)All phones is in G.729 (intraregion and interregion), if i change codec, users feel differences in quality and surely I will do note :\
It seems strange that cisco has not thought of a way to inserirt an MTP automatically or via a "region" when the phones does not see...

The Region config between the transcoders and each site will be checked. If neither side is talking G711 to the transcoder you will need a universal transcoder (http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/rel_notes/7_1_5/cuc m-rel_notes-715.html#wp1768778). With CUCM 9.x+ you can accomplish something similar with Audio Codec Preference Lists. -- Adam On 8/24/2016 3:29 AM, Mauro Celli wrote: Hi, i have three site, Cucm is in SiteA SiteB and SiteC have a vpn to SiteA SiteB and SiteC they can not have a vpn between them for safety reasons. To make calls from SiteB and SiteC, i have to enable "use trusted relay point" for all phone of B-C sites, and insert MTP. But if i enable this TRP, when a SiteB phone call another SiteB phone, MTP is inserted in call and i consume wan bandwith. How i can limit trusted relay point only when it is really necessary? I have CUCM 8.6 Thanks _______________________________________________ cisco-voip mailing list mailto:cisco-voip@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-voip
