Hello Every one I need to enable Asterisk to route external land line calls to the PSTN. Regarding our environment, we have Cisco CallManager (3.3.4) to which IP phones are connected. E1 terminated on a couple of As 5300's which are controlled by a soft switch (Cisco PGW200 Call Control). What is the best scenario to route external calls to PSTN. Should I use SIP or just connect Asterisk to Cisco CCM. Any technical details are very much appreciated. Thanks Walid -------------- next part -------------- An HTML attachment was scrubbed...
