SIP Calls Re-Originating

[S Kumar]

We have the following DP on Cisco7206.

!
dial-peer voice 8 voip
huntstop
destination-pattern .T
progress_ind connect enable 8
progress_ind disconnect enable 8
media flow-around
redirect ip2ip
session protocol sipv2
session target ipv4:1.2.3.4
session transport udp
dtmf-relay rtp-nte sip-notify
codec g711ulaw
fax rate 9600
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none
!

Calls comes from our carrier and we terminate it to cuustomer's gateway. Our router re-originate the call if customer's gateway send us SIP 486.

We have done huntstop, it should not retry in case of call failure. Our cutomer does not want us to retry in case they are sending us 486. I am not sure what to mentioned in the dial peer to stop retry.

Please help.

Remove the retry invite, if this exists under sip-ua.

[S Kumar]

There is nothing specifically configured. Looks like following are the defaults settings. What are te recommed values?

ROUTER#sh sip-ua retry
SIP UA Retry Values
invite retry count = 6   response retry count = 6
bye retry count    = 10  cancel retry count   = 10
prack retry count  = 10  update retry count    = 6
reliable 1xx count = 6   notify retry count   = 10
refer retry count  = 10  register retry count = 6
info retry count   = 6   subscribe retry count = 6
options retry count = 6

[prashanthpatha]

Since you haven't set anything, it is taking the default values which 6.

play with the retry invities. Set it to either 1 or 2 and see if this makes a difference.

I am going to try this out. What can be the possible side effects of changing the retry count to 1?

[S Kumar]

This did not help. We are having the same problem. Here is how it

looks:

ROUTER#sh sip-ua retry
SIP UA Retry Values
invite retry count = 1   response retry count = 6
bye retry count    = 10  cancel retry count   = 10
prack retry count  = 10  update retry count    = 6
reliable 1xx count = 6   notify retry count   = 10
refer retry count  = 10  register retry count = 6
info retry count   = 6   subscribe retry count = 6
options retry count = 6

Can we try anything?

sip error 486 is ISDN cause code 17
try below in global config mode:

no voice hunt user-busy

[S Kumar]

Our customer's gateway responds with mainly 2 SIP responses:

SIP 486

SIP480

I have done the following no our router

ROUTER(config)#no voice hunt  user-busy
ROUTER(config)#no voice hunt  no-answer
ROUTER(config)#no voice hunt  no-response

ROUTER(config)#no voice hunt  temp-fail

but still calls are being reoriginating. Please help.
