receive ISDN call en-bloc

[Istvan Balla]

is there a way to configure ISR4300 SIP gw that has 1 ISDN PRI E1 to receive the called number en-bloc ( ENBLOC ) from PSTN provider instead of overlapping 1by1?

must provider agree in that if my configuration is ENBLOC, they send whole DNIS in SETUP to my router?

Hi Istvan,

Cisco routers can work in both Enbloc and Overlap modes as explained in the following doc

http://www.cisco.com/c/en/us/support/docs/dial-access/dial-on-demand-routing-ddr/23382-isdn-overlap-prob.html

You can either check with your Telco if they can send the DNIS as per your requirement, else you always have the option to configure your gateway accordingly.
