Srst call forwarding

Hello 

 

I have centralized cucm and unity and in the branches we installed router with SRST function 

In normal scenario call come to PSTN in branch forwarded to call handler in centralized unity but if the WAN is down the calls should be go to user in the branch directly. 

 

It is work with me with SCCP phones with alias command under ccm fallback.. 

 

But with SIP phones i can not do. 

 

 

Please advise

Re: Srst call forwarding

It depends on how your dialplan configured at the gateway. The best option
is to globalize the called number at the input voice port or trunk at the
gateway then forward that to CUCM. At the same time using configure your
SRST DNs with primary dn as standard extension format (e.g. 4-digits) and
secondary dn as globalized format (e.g. e164).

This way when your srst dns register, the calls will work with same config.
