Hi Ahmed,

Read this below guide which is quite handy to deploy CMS using expressway for difference scenarios. as per my understanding you can only make calls out from CMS space to SIP URI.

Hi farrukh,

thanks for your help, now i deployed MRA and B2B (for jabber also), for now outside user (sip endpoint or jabber other domain) can call cms room, but no media stream, and after few seconds its dissconnected.

when cms room try call out, it failed.

i already configured B2B in expressway C & E, but i still not found any clues. i asking security guy, they said no ports blocked

Hi Ahmed,

check below link

https://cmslab.ciscolive.com/

this will help you to configure CMS step by step.

further please check that "media termination point required" is unchecked on CMS SIP trunk in CUCM, and are you using the same domain as CUCM for CMS? coz it is recommended to user sub-domain for CMS i.e cms.domain.com.

if the CUCM and CMS has same domain then create SIP route pattern withe the pattern "yourdomain.com" and point it to CMS trunk
