I have a 3845 running as PSTN gateway with 3 ISDN PRI ports. SIP trunks connect this gateway to a few CME's.
Outgoing calls are established not quick enough(for some users) as it takes aboiut 8 seconds to call a mobile phone. I find a command 'isdn overlap-reeiving' in the doc, but is it used for incoming calls? How can I configure overlap dialing for outgoing calls to fasten the connections?
Thanks in advance.
