Expressway outbound B2B calls fail

Hello,

 

I'm working with Expressway v8.10 for MRA and B2B calls.  For B2B calls, I am able to be called from the outside (incoming calls succeed). But I am not able to call to the outside. Specifically, I want to call to WebEx and to Cisco Spark.

 

I have a DNS zone defined in Expressway-E and a search rule for this zone. Attached are the screenshots of the configuration.

 

These are the logs and the search history in Expressway-E:

My Expressway-E has advanced networking (two interfaces). I try DNS Lookup and it shows SRV and type A records for the domains I tested. I tested with my Cisco Spark account and with 6656109786@b2b.ciscotac.net (Cisco TAC B2B call tool).

Hello HeribertoVV

 

This thread look so old but since no replied and looking your issue explained suspected an issue of firewall. 

Did you check if there was any packet inspection behind this?
