Hi guys,

 

we are connect two building through L2VPN ( HQ & Branch ).

 

users phones in ( Branch ) are connected to ( HQ )'s CUCM without any issues, but the calls between the users in these buildings sometimes works and sometimes having issue with audio. ( ring reach but the caller cannot hear the responder ).

 

HQ and Branch are allowed those ports :

 

TCP- UDP  24576 - 32767

TCP  5060 - 5061

 

Phones uses SIP protocol
