> Key: ASTERISK-25539
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-25539
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Channels/chan_sip/General
> Affects Versions: 1.8.22.0
> Environment: Debian 6.0.7, 64 bit.
> Reporter: David Cunningham
>
> We have an issue where:
> 14:19:08 Fax machine makes call to Asterisk
> 14:19:08 Asterisk dials SIP termination provider
> 14:19:23 SIP termination provider accepts call
> 14:19:28 SIP termination provider sends T.38 re-invite
> 14:19:28 Asterisk sends T.38 re-invite to fax machine
> 14:19:28 Fax machine accepts re-invite
> 14:19:33 Asterisk appears to do nothing for 5 seconds and then sends "488 Not acceptable here" to SIP termination provider
> This is in the attached Asterisk trace, where the call from the fax machine has ID BC3FB901-81AF11E5-8D388D32-AD053ED at BB.BB.46.68 and the call to the SIP termination provider has ID 026a9cbd104dbb311dc9963a05702766 at AA.AA.224.228:5060.
> Could you please advise why after getting the 200 OK at 14:19:28 it takes 5 seconds for Asterisk to send the "488 Not acceptable here", and why the 488 is sent?
> I notice there are a lot of "Bridge still active. Delaying destroy of SIP dialog" messages relating this call, but I think they're harmless?
> Thanks for your help.
