[Dalius M. (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=211323#comment-211323 ] 

Dalius M. commented on ASTERISK-22686:
--------------------------------------

It is everything ok with IP addresses.
PBX has 2 IP's: 
82.135.219.194
other local and does not used in this call.

My softphone has:
78.59.84.76

Provider has: 
85.206.138.84


I have found that my issue is related to
https://issues.asterisk.org/jira/browse/ASTERISK-20633

I have configured in sip.conf "ignoresdpversion=yes" and everything looks fine now.

> Hello,
> We have found strange Asterisk issue.
> Phone attached to Asterisk (A) calls to SIP provider (B).
> (B) Puts call on hold and does attended transfer to (C).
> Asterisk plays MOH to (A) phone. When transfer is done, SIP provider sends INVITE, but Asterisk does not strart to send RTP.
> SIP provider told us that it is Asterisk bug.
> I have attached dump file from PBX's side.
> There is 2 VoIP calls, one from my softphone (IP 78.59.84.76) to PBX (IP 82.135.219.194) and other from PBX to SIP provider (IP 85.206.138.84).
> I have also tried Asterisk 11.3 version and Cisco SPA 504G (firmware 7.5.5) phone with same results, transfered calls are dropped
