Deflect Command not generating REFER Packet and making freeswitch Hang for 10 Sec

[surabhigarg1234]

HI Team,

Facing issue with Deflect command where deflect command is not generating REFER packet and getting hang for 10 sec.

My call scenario is:

1. Made call using linphone to freeSWITH.
2. Call lands to a diaplan and from dialplan I am calling mod_httapi application'
3. mod_httapi application sends document to answers the call
4. then mod_httapi application sends document to Play 2-3 music file
5. Then mod_httapi application transfers the call to another dialplan using "transfer" application
6. In transferred dialplan, I am deflecting a call to another sip endpoint i.e. ""
7. Post deflect, no REFER packet generated and freeswitch hanged for 10 sec.
8. Post 10 sec freeswitch channel gets deleted but SIP session remain open without BYE

Seems in terms of code, freeswitch gets stuck in mod_dptool.c:

switch_channel_wait_for_flag(channel, CF_MEDIA_ACK, SWITCH_TRUE, 10000, NULL);

Any help here would be appreciated.
