There is a query about exytension mobility wherein a user logs in into IP phone through Extension mobility across WAN.After user logins and WAN link goes down, whether EM will still continue to work.

Is it possible to configure EM on SRST ?

Note that when SRST and EM are on at the same time, the phone will be stuck with a previously logged in user's profile because there is no logout/login prompt for a new user to login when in SRST mode.

No EM login during srst

If a EM user is not logged in to a phone, the DN of that user is unknown

for the SRST router in fallback mode. In order to get around that, you

are trying to use 'default-destination 901732746839'. If we take a look

at the IOS command reference guide:



This command is no longe rused you need to use alias commands

Hi Sir ,

What u are trying to confirm is that the IP phones which have already logged in thorugh Extension mobility will keep on working , when WAN link goes down & phones register to SRST mode with same directory number.Hence, IP phone users can work internally seamlessly.

Secondly, Users from the outside PSTN world won't be able to make call to IP phone users . To make Analog phone work connected on FXO port of Voice Gateway router , we need to configure default destination number command.

Pls. confirm
