[SR-Users] Network Architecture Question

[Rob Watkin]

Hi Stoyan,

Does that mean that you use Asterisk as pure SIP PSTN Gateways? I imagined
Asterisk as a physical PSTN gateway but thought that Kamailio/RTPProxy
would scale out better for pure SIP. I was planning to use Asterisk or
FreeSWITCH as a media server for hold, VM, conference and IVR.
