Hi We have two asterisks registered as UA's. SER is acting as a proxy server. We want to make calls between two asterisk users through SER. One asterisk server has extensions starting with 2, and the other one has extensions starting with 4. We route the calls based on the first digit. We are unable to call from an extension on one asterisk server to the other asterisk server. "rewritehostport" doesn't seem to be doing the trick for us. Does anyone have a solution? Below is our ser.cfg file:
