Callmanager SRST with H323 gateway issue.

[norm.trees]

Hi,

I am trying to set up SRST with callmanager and a h323 gateway (not an MGCP gateway)

I can get it to fail over, but I am unable to retain the extension number, so the phone registers but is unusable.

pls see parts of config,

application

global

service alternate default

call-manager-fallback

max-conferences 8 gain -6

transfer-system full-consult

ip source-address 10.1.1.1 port 2000

max-ephones 30

max-dn 30

system message primary Operating in Backup Mode

dialplan-pattern 1 565656 extension-length 4 extension-pattern 1220

dialplan-pattern 2 54321. extension-length 4 extension-pattern 140.

dialplan-pattern 3 54322. extension-length 4 extension-pattern 141.

am I missing anything here?

Thanks

Norm.

Are you prebuilding your ephones and ephone-dn's in your config? If not you have to set the srst mode auto-provision mode under you telephony service

all SRST mode ON (include both learned DNs and phones into show running)

dn SRST mode ON (include only learned DNs into show running)

none SRST mode ON (include NONE of the learned DNs/ephones into show running)
