Hello Ammar,

As per the error you required more memory for ESE module to work, you have only 512MB memory. Now I assuem you configured on Service-Module right ? It will work fine without any issue.

Next for your voicemail not working can verify that you have configured the SIP dial-peer to reach the Voicemail tiggered phonenumber i.e. 700 in your case.

dial-peer voice 101 voip

session protocol sipv2

session target ipv4:

destination-pattern 700
