[SIPForum-discussion] No Speech patch after call is put on hold while calling to Cisco Agent

[vijay.mishra at wipro.com]

Hi,
 
I have an issue with the Call Hold scenario.
 
When Nortel Cs1k Call to Cisco Agent Hold Retrieve is not working.There
is no Speech path after hold and Retriev.
 
Sniffer Traces captured is shown below:
 
Cs1k                                Cisco
 
--------Invite------------------------------>
<------100trying----------------------------
<-------183 session progress SDP---
-----------options------------------------>
<---------200 Ok (SDP for Invite)-----
---------------Ack-------------------------->
<----------Update---------------------------
-------------200 Ok----------------------->
----------------Bye-------------------------->
<--------------200 Ok-----------------------
 
As per the diagram When Cs1k is pressing Hold button no Reinvite can be
seen.There are two things which looks to be wromg wrong.
 
i)When CS1k sends the option it does not get the reply with 200 Ok for
this option.
 
I would like to know if missing 200 Ok for option request could result
in Re-Invite not being send after pressing  Hold key.
I am attaching Sniffer Traces and Sip logs for better understanding.
Thanks & Regards
Vijay Mishra
