CCME SIP trunk problem

[laposilaszlo]

Hi,

i am trying to set up a sip trunk on a 2901 CCME.

this is my sip-ua conf:

sip-ua

credentials username xxxxx password xxxx realm small.eurovoice.ro

authentication username xxxxx password xxxx

nat symmetric role passive

nat symmetric check-media-src

no remote-party-id

srv version 1

retry invite 2

retry register 10

retry options 10

timers connect 100

registrar dns:small.eurovoice.ro expires 600

debug:

REGISTER sip:small.eurovoice.ro:5060 SIP/2.0

Via: SIP/2.0/UDP xxxxx:5060;branch=z9hG4bK13FA7A6

From: <sip:xxxxx@small.eurovoice.ro>;tag=B313BBCC-E60

To: <sip:xxxxx@small.eurovoice.ro>

Is this correct, the From and TO beeing the same?

Doesent the From has to be xxxxx@my ip address?

thank you,

laszlo

Hello Laposilaszlo

I have some problems with SIP Trunk too, take a look on this config:

!--- SIP UA Configuration ---

sip-ua 
 authentication username xxxxxxxxx password xxxxxxxxxxx
 no remote-party-id
 retry invite 2
 retry register 10
 retry options 0
 timers connect 100
 registrar dns:domain.test.com 
 sip-server dns:domain.test.com
  host-registrar


!--- Voice Class and Service VoIP Configuration ---

###voice service voip###
 allow-connections sip to sip
 allow-connections h323 to sip
 allow-connections sip to h323
#####Dont forget to allow protocol internetworking#####

Other important thing dont forget to set an ip route to the network of the sip trunk, because
the network of the phones must reach the network of the SIP Trunk

Take a look on this guide

If your provider have a dns i think is correct to provide domain name on the SIP URI like
sip:14085551234@gateway.com

If doesnt work post the output of these commands

show sip-ua calls
debug ccsip calls
debug voip ccapi inout
