SRST SIP

[Ahmed Awida]

Hi Guys.

For Cisco Sip phones,is all what needed for srst is to add the srst reference in the device pool?

For sccp,it works normal ,i put the the same srst ip of sccp in the sip field,Is that all what needed ?

For 3rd party like Avaya,Polycom,GrandStream,Do i need to configure Voice register global and pool for each phone cause they don't register in srst?

Thanks.

Ahmed,

It doesnt look like 3rd party sip phones ares upported in SRST mode...

SRST reference is obtained from the device's device pool. But I doubt if the 3rd party sip phones have the srst configuration in them to contact the SRST gateway
