Thanks your feeback and the document you enclosed.

But I think I have configured the item for every mode, pls refer to the comment below, is that right?

My question is if each item is right, is that ok if I mix every item under one dial-peer to support both inbound/outbound in SRST mode and the normal call in MGCP mode?

dial-peer voice 1 pots

destination-pattern 9T /for SRST Outbound/

incoming called-number . /for SRST inbound/

direct-inward-dial /for SRST inbound/

service mgcpapp /for MGCP in&out/

application MGCPAPP /for MGCP in&out/

port 0/0/0:15

Best practice is to do the following

1. Create a seperate pots dial-peer for incoming calls.

2. create a seperate pots dial-peer for outgoing dial-peers

example below:

dial-peer voice 1 pots

incoming called-number .

direct-inward-dial

port 0/0/0:15

dial-peer voice 2 pots

destination-pattern 9T

progress_ind alert enable 8

progress_ind progress enable 8

incoming called-number .

port 0/0/0:15

These commands are required whether you are using srst or not and they will work for both srst and non srst situations

lastly depending on the IOS version you are using, you dont need the application mgcp or service mgcp under your pots dial-peer. ANd even if you do you only need one of them and not both

Example of mgcp config below

ccm-manager fallback-mgcp

ccm-manager redundant-host 192.168.2.12

ccm-manager mgcp

ccm-manager music-on-hold

ccm-manager config

direct-inward-dial

Thanks. I know what's your meaning.

But I DO want to know whether I can mix some dial-peer to one which includes SRST in , SRST out and MGCP in/out ? Just like the configuration I enclosed aboved.

As you know, normally, many dial-peers need to be configured for SRST, it's bored, I just want to simplify the configuration.

Is that OK?
