I am setting up a site in Switzerland and could use some help on the MGCP E1 PRI gateway settings. I beleive the telco is Swisscom. What would be typical settings for:
Pri Protocol type?
Channel IE type?
Also I believe the D-channel is channel 15 - is that correct.
Anything else I need (I have done plenty of gateways in the US but this is my first one in Europe).
Use defaults value in CUCM
controller E1 0/0/0
pri-group timeslots 1-31 service mgcp
no ip address
isdn switch-type primary-net5
isdn incoming-voice voice
isdn bind-l3 ccm-manager
no cdp enable
ccm-manager redundant-host x.x.x.x
ccm-manager config server x.x.x.x
mgcp call-agent x.x.x.x 2427 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode out-of-band
mgcp rtp unreachable timeout 1000 action notify
mgcp modem passthrough voip mode nse
mgcp package-capability rtp-package
no mgcp package-capability res-package
mgcp package-capability sst-package
no mgcp package-capability fxr-package
mgcp package-capability pre-package
no mgcp timer receive-rtcp
mgcp sdp simple
mgcp rtp payload-type g726r16 static
mgcp bind control source-interface GigabitEthernet0/0
mgcp bind media source-interface GigabitEthernet0/0
mgcp profile default
I also find a lot of mainland Europe use 'framing no-crc' on their E1s. Try that if it doesn't come up.
Defaults should work ok .Use "PRI EURO".
Be sure that outgoing calls are signalled properly (calling number without leading "0", "national", called "unknown").
If it's not correct it will be masked by the provider and the main number will be signalled out.
You maybe find some useful info here about the Swiss Numbering Plan:
