[cisco-voip] SIP gateway config

[Ahmed Elnagar]

I think you can force early offer from the gateway to avoid using MTP.

Only if you need SIP early media from CUCM.

Yep, have that already.  Gig0/1.110 has the IP address configured on the
SIP trunk in CUCM.  

 

voice service voip
 sip
  bind control source-interface GigabitEthernet0/1.110
  bind media source-interface GigabitEthernet0/1.110

 

I also have the following:

 

voice class codec 1
 codec preference 1 g711ulaw
 codec preference 2 g729r8

dial-peer voice 100 voip
 destination-pattern ....
 session protocol sipv2
 session target ipv4:172.21.20.10
 voice-class codec 1
 dtmf-relay rtp-nte
 no vad
dial-peer voice 1 pots
 incoming called-number .

You have to bind signal and media traffic out of the router to the CUCM
with the IP address you have configured on CUCM "by default CUCM reject
calls with source address other than the configured"

 

Try the below on the gateway:

 

voice service voip

sip

bind all source-interface "interface configured on CUCM"

Does anyone happen to have an example SIP gateway config for an ISR?
CUCM 8.0(2) with a SIP trunk to a 2921 gateway (15.0.M1.12) with a
standard PRI for PSTN access.  I have outbound working, but inbound
gives a fast busy with a 401 Unauthorized in the SIP debug.

 

Thanks,

Brian
