[SR-Users] Keepalive dialog with SIP/TLS OPTIONS

[Henning Westerholt]

Hello,

this sounds strange. There is no TLS specific code in the dialog module.
As a workaround, you could use for example SIP Session Timer for periodic re-INVITEs.

Cheers,

Henning

Subject: [SR-Users] Keepalive dialog with SIP/TLS OPTIONS

Hello!

In order to keep the SIP/TCP connection alive for some specific clients (more precisely, specific firewalls) in long calls, I use periodic SIP OPTIONS probes through the dialog module.
I noticed that when subscribers are using the SIP/TLS protocol, such keepalives are not sent (with SIP/UDP and SIP/TCP working well).
I did not detect any obvious errors in the debug mode.

Are there any ideas why the messages are not being sent for SIP/TLS leg?
