We got a CUCM ver 10.0.1.10000-24.
Our client has about 170 Ip Phones user on one remote site.
We have configured SRST ont that site, here you have router's configuration ( related to SRST):

During tests about 60 Ip Iphones got registration with proper Directory Numbers. But when we try to with internals call from any DN, we got:
a) Calling Ip Phone: rings ONE time and call falls on reorder tone.
b) Called Ip Phone: keeps ringing..
And when we call from PSTN to internal pilot, the calls fall too and internal Ip Phone keeps ringing.
IMPORTANT tip: Ip phone's network 10.16.5.0/24 is not directly connected to our SRST voice gateway, but we have full access between this network and the voice gateway..
- Do you know what is missing on our voice gateway configuration?
- Do you know how I can set up a specific group of Ip Phones to get this registration 50 over 170?
Best regards
